A forklift that spends most of its shift on smooth concrete may only cross a battered loading apron a few times a day. Another truck works in the same yard but drives past nails, metal strapping and pallet debris on every trip. Both are “outdoor forklifts,” yet they give the tire buyer two different problems to solve. Pneumatic forklift tires usually make the stronger case when cushioning on uneven ground matters. Solid forklift tires make more sense when punctures and lost operating time are the bigger concern. Neither construction is a universal upgrade: the approved wheel, load and duty must still match the tire. Start with the surface, not the tire label Walk the route the loaded truck actually takes. Look at the transitions from warehouse floor to dock plate, the joints in the yard pavement and the areas where packaging scraps collect. A flat concrete yard with scattered sharp metal is not the same application as a broken asphalt approach with almost no debris. The word “yard” alone will not settle the choice. Where pneumatic tires earn their place An air-filled tire can absorb some of the impacts from rough joints, patched paving and mixed yard surfaces. That cushioning matters on repeated loaded trips, particularly when operators leave a smooth warehouse and cross uneven ground. The trade-off is familiar: tire pressure and puncture exposure become part of the maintenance routine. On a route with frequent sharp debris, any ride benefit has to be weighed against downtime. Where solid tires are worth considering A solid tire does not lose air through a puncture. For yards where nails, scrap or discarded pallet hardware regularly reach the driving path, that removes one common cause of an unscheduled stop. The firmer construction, however, transmits more of the surface irregularities through the truck. Solid tires still need inspection for wear, damage, heat build-up and suitability for the machine; “no air pressure” does not mean “no maintenance.” Solid vs pneumatic forklift tires: a practical comparison Decision point Pneumatic construction Solid construction Broken joints and uneven paving Air cushioning can improve ride over variable ground Less cushioning; assess vibration and surface severity Nails or sharp debris Punctures and air loss are potential downtime causes No air to lose from a puncture Daily checks Correct inflation pressure is essential No inflation check, but wear and damage still require inspection Long shifts Consider pressure, heat and route conditions Consider heat, wear and continuous-duty suitability Before ordering Confirm size, PR, rim, wheel load and pressure Confirm size, mounting form, rim and duty-specific load data This table compares construction characteristics, not tested performance figures for a particular forklift. The tire specification and the equipment maker’s approval take precedence over general rules. Three yard situations that change the answer 1. A loading apron with cracked concrete The route runs from an indoor loading bay across worn joints and patched pavement before returning to the warehouse. If puncture hazards are limited, cushioning becomes an important reason to review a pneumatic option. Inspect the worst section with the forklift loaded; a surface that looks manageable when empty can feel quite different during repeated loaded travel. 2. A scrap-prone outdoor transfer area A second truck crosses mostly hard pavement, but loose fasteners and pieces of metal strapping routinely appear near the loading lanes. Here the cost of a puncture may outweigh the value of extra cushioning. A suitable solid tire deserves a closer look, alongside housekeeping improvements. Choosing a solid tire is not permission to leave the route covered in sharp material. 3. One truck, warehouse in the morning and yard in the afternoon Mixed duty is the awkward case. Indoor turning, yard transitions, loaded travel distance and debris all matter. Rather than choosing from the word “outdoor,” ask which problem repeatedly interrupts the shift: harsh impacts or tire damage. If both are substantial, the fleet may need route improvements or a review of how the trucks are assigned, not simply a different tire construction. What LANDER LS658 and LS659 actually offer In LANDER’s forklift tire range, the LS658 pneumatic forklift tire is positioned for outdoor and mixed-surface material handling where cushioning, traction and machine stability matter. The LS659 solid forklift tire is positioned for demanding material handling where puncture avoidance, stable handling and long working hours matter. These are the manufacturer’s stated applications, not approval for every forklift working on those surfaces. For a yard with rough transitions but little sharp waste, the LS658 is the more natural starting page to review. When sharp debris and puncture-related stoppages dominate, compare the LS659 instead. On the customer site, the LS659 is presented as a multi-rib solid design; its application is not restricted to indoor warehouses. A shared tire size is not a fitment approval The 5.00-8 marking appears in both model ranges, but the catalog rows are not identical. LANDER lists the LS658 5.00-8 pneumatic tire with a 470 mm outside diameter, 137 mm section width and 3.50D rim. For an LS659 5.00-8 solid tire on a 3.50D-8 rim, the published row lists a 460 mm outside diameter and 136 mm section width. Those figures are model-specific examples, not a claim that one can replace the other. The remaining specification fields also differ by construction. The LS658 table includes PR, load and inflation pressure by size. The LS659 table distinguishes mounting details and load capacities for different wheel positions and operating conditions. A number taken from one table should never be copied across to the other. The truck’s tire and wheel approval, axle loading, mounting method and clearances decide whether a proposed change is possible. Buyers sometimes ask whether solid tires can simply replace the pneumatic tires on a forklift because the nominal marking matches. There is no safe blanket answer. If the current tire construction changes, have the equipment manufacturer or qualified fitment specialist confirm the wheel assembly and operating limits before ordering. Questions to settle before requesting a quote A short route description is more useful than a long generic product request. Include these details when discussing a forklift tire replacement: What proportion of the shift is on smooth concrete, broken pavement or mixed surfaces? Are punctures an occasional incident or a recurring source of downtime? What truck model, front/rear wheel position and approved tire mounting arrangement are involved? What are the verified wheel or axle loads, expected operating speeds and shift pattern? Is the proposal a like-for-like replacement or a switch from pneumatic to solid (or the reverse)? Once those points are established, review the relevant LANDER model page and send the confirmed requirements through Contact LANDER. Request the exact tire construction and size rather than approving a substitute by appearance alone. Conclusion The right construction depends on what repeatedly challenges the forklift: impacts from rough ground or interruptions caused by sharp debris. Pneumatic tires can provide useful cushioning in mixed yards; solid tires can reduce air-loss downtime where puncture hazards dominate. LANDER’s LS658 and LS659 provide two starting points, but the final decision belongs to the approved wheel and operating duty. Buyer FAQ Are solid forklift tires always better outdoors? No. Solid tires can be a good choice on outdoor hard surfaces where punctures are common. On rough or uneven routes, the lack of pneumatic cushioning is an important trade-off. Surface conditions and approved fitment both matter. Can pneumatic forklift tires work in a warehouse? Potentially, if the truck is designed and approved for that construction. A warehouse-to-yard route may benefit from pneumatic cushioning, but the equipment’s wheel arrangement and space constraints must be checked first. Do solid forklift tires require maintenance? Yes. They do not need inflation checks, but operators still need to look for cuts, uneven wear, heat-related damage and changes in handling. Debris removal and route maintenance remain important. Can LS658 and LS659 be swapped at the same nominal size? Not automatically. Even a shared marking such as 5.00-8 does not establish identical dimensions, mounting conditions or load ratings. Verify the actual equipment specification and obtain the necessary fitment approval before switching construction.

A quotation that says “LS658, 900 kPa” may look specific. It is not. On LANDER’s LS658 page, 900 kPa appears beside both 5.00-8 and 300-15. The first has a 3.50D standard rim and a listed 1,295 kg load. The second shows an 8.00 rim and 6,825 kg. Those details would send a buyer toward different tires even though the pressure matches. The order therefore needs a size and an identified forklift, not merely a tire family. LANDER publishes the tire data. The wheel fitted to the truck, its load and the truck maker’s guidance supply the other half of the decision. The LANDER homepage is the broad company entry, while About LANDER gives the company background behind the product categories. Find out what is being replaced A photograph of the old sidewall marking is more useful than a handwritten size copied from an old spreadsheet. Photograph the rim identification if it can be seen. Record the truck model and whether this is a front or rear wheel; the supplier cannot infer either from the word “forklift.” If the marking is gone, do not borrow a size from a similar-looking truck. State that the existing marking is unreadable and have the wheel and approved fitment identified. A move from solid to pneumatic construction calls for a fresh fitment check. On its LS659 solid tire page, LANDER highlights puncture avoidance; the LS658 page discusses cushioning and traction on variable ground. The truck maker’s wheel guidance still has to settle whether the change is possible. Give the supplier the working conditions in ordinary terms. “Outdoor yard” could mean smooth paving or a route littered with sharp scrap and broken joints. Tell the supplier about the surface and the loaded route. LANDER lists LS658 for outdoor yards, loading areas and mixed industrial work; the machine’s actual assignment is more specific than any of those labels. Read the complete size row The LS658 specification page lists a standard rim, dimensions, load and pressure for each size. These three published rows show why copying one field in isolation is risky: Size PR Diameter Width Standard rim Listed load Listed pressure 5.00-8 10 470 mm 137 mm 3.50D 1,295 kg 900 kPa 7.00-12 14 683 mm 192 mm 5.00S 2,670 kg 1,000 kPa 300-15 20 840 mm 300 mm 8.00 6,825 kg 900 kPa The 7.00-12 listing is 1,000 kPa, so the family has no single pressure setting. The two 900 kPa entries still differ sharply in rim and load. Read the rim, size and dimensions with the pressure, then check the exact offered tire against current equipment guidance. Do not compare the load column with the forklift’s lifting-capacity plate. The load relevant to a tire is the load at its wheel or axle in the intended configuration. When that number is missing, write “wheel/axle load pending” and ask for a fitment review. Leaving the cell open is safer than copying the lifting-plate number. Keep PR with the row; it does not clear a wheel position by itself. Put a proposed change in writing If the old sidewall says one size and the reply names another, print both markings. The offered rim, dimensions, PR, load and pressure should sit beside the original request, with each change visible. That gives the truck’s fitment approver a concrete question. Price alone will not tell the buyer whether the proposed tire clears the machine or suits its wheel. For the RFQ, place the old sidewall and rim photographs beside the truck model, wheel position and quantity. Add the route description and any verified wheel or axle load. If the load is unknown, say so instead of copying the lifting-capacity plate. Delivery and document requirements can follow. Ask for the exact offered LS658 size and current data. LANDER’s forklift range and product listing help with browsing; the LS658 page holds the size details used here. For company questions or a quotation request, use Contact LANDER. File the approved size with the purchase order. Receiving can then check the delivered sidewall marking before fitting, against the same size the fitment reviewer approved. Before anyone compares totals, read the offer once as a fitment record. Check the offered marking against the request, the rim against the wheel record, and the listed load and pressure against the same size row. Then set the machine’s confirmed wheel or axle load beside the work described in the RFQ. An unresolved answer belongs in the open-items note and should go back to the person responsible for the forklift. That keeps a missing measurement visible instead of allowing a familiar model name or a shared pressure figure to decide the purchase. The three rows also show how quickly a size difference becomes a machine difference. The table lists 6,825 kg for 300-15, a little more than five times the 1,295 kg shown for 5.00-8. Its outside diameter is 840 mm rather than 470 mm, and its width is 300 mm rather than 137 mm. Those comparisons do not approve either tire for a truck. They do show why the shared LS658 name or shared 900 kPa figure cannot justify moving from one marking to the other. The standard rim changes from 3.50D to 8.00 as well. A supplier who sees the old marking and wheel record can explain the proposed row; a supplier who sees only the model name has to ask for those details. The same table helps when a requested size is unavailable. The buyer can place the old row and the offered row side by side and identify the changed field. If the offered diameter, width or rim is different, the fitment question should be answered before the price is approved. A note saying “alternative accepted” does not preserve the reason for the decision. The approval record should retain the offered marking and the row values that were reviewed. At receiving, compare the delivered sidewall with that approved line. A mismatch may be a picking error, but it should be resolved against the quotation before the tire reaches the wheel. That is the point at which the catalog data, the forklift record and the purchase order meet. Conclusion A tire model name is useful for finding a catalog page. For an LS658 order, the decisive record is the exact size row matched to a particular forklift and wheel, with any substitution assessed before the order goes out. Buyer FAQ Does LS658 have one pressure? No. The official table lists 900 kPa for 5.00-8 and 300-15, but 1,000 kPa for 7.00-12. Pressure must stay with the exact size row. Is listed load the forklift lifting capacity? No. The catalog load belongs to the tire row. The machine review concerns the load at the relevant wheel or axle in the planned configuration. What should accompany an RFQ? Send the forklift model and wheel position, sidewall and rim photographs, quantity, route description and any known wheel or axle load. Keep the exact LS658 size row in the request. What about a substitute size? Keep the requested and offered markings together. Record the offered rim, dimensions, PR, load and pressure, then obtain the fitment decision before approval.

The pattern name on a quote can stay the same while the tire specification changes. That is exactly the point worth discussing when comparing LANDER’s LS669 in 385/65R22.5 with its 385/55R22.5 version. There is no point negotiating the alternative until the specification has been settled. On the LANDER LS669 sheet, those two lines have different rims, different outside diameters and different maximum loads. Calling the second one an alternative does not resolve any of those differences. For a buyer working through the TBR tire range, this is a useful example of what to put on the desk before agreeing to a size change. 385/65R22.5 vs 385/55R22.5: How to Read the Tire Sizes Keep the approved size on the enquiry, even while discussing another option. The vehicle model and the markings on the wheel belong beside that size. We would put the alternative on a separate line below it. That way, whoever answers the enquiry can see both the original requirement and the option being discussed. Reading from left to right gives a nominal width of 385 mm, followed by the profile. That profile expresses section height relative to section width, in percent. At the other end of either name, the diameter designation is 22.5 inches. That is where 65 and 55 differ; the R in each name denotes radial construction. Useful information, certainly, although it is still a size designation rather than permission to fit the tire to a particular vehicle. What Do the Published Figures Actually Show? Here are the two entries from the LANDER LS669 specification. This is a comparison of that model, not a universal chart for all 385-size tires. Published specification 385/65R22.5 385/55R22.5 Ply rating 24PR 20PR Load index 164 160 Speed symbol K K Standard rim 11.75 12.25 Section width 389 mm 386 mm Overall diameter 1,072 mm 996 mm Tread depth 14.5 mm 14.5 mm Maximum load 5,000 kg 4,500 kg Listed inflation pressure 900 kPa 900 kPa   There is just 3 mm between the width entries, 389 and 386 mm. The diameter entries tell a different story. Subtract 996 from 1,072 and there is a 76 mm difference to discuss. The same exercise with the maximum-load entries gives 500 kg per tire. It is worth leaving both differences written on the comparison sheet, even when the quoted prices are close. Not every field changes. There is a K in both speed-symbol cells, 14.5 mm in both tread-depth cells and 900 kPa in both inflation cells. Taken together with the other entries, however, those matches do not describe two identical specifications. For an enquiry about 385/65R22.5 tire dimensions, we would attach this whole table. It leaves the person reviewing the order with the rim reference as well as the measurements. What Needs Attention on the Vehicle? There is a point where the purchasing conversation needs a technical answer. For a proposed size change, we would want the vehicle manufacturer’s guidance and the fitment provider’s review on file before approving the order. The questions below are a practical way of arranging that discussion. Is the wheel combination approved? The rim references on these LS669 rows are 11.75 and 12.25. Neither entry should be read as a complete approved-rim list. Obtain that information for the tire being offered, then compare it with the actual wheel. Approval covers width and contour as well as diameter. The wheel’s load and pressure limits remain limits, even where the tire itself has a higher rating. Has the clearance been checked? Clearance deserves a physical review, not an estimate from the catalog. USTMA’s commercial tire manual addresses movement through the suspension’s travel and, for steering positions, full turns in both directions. A diameter change can also bring instruments and electronic systems into the review, including a possible need for recalibration. Which checks apply is a question for the vehicle manufacturer. Do not turn a catalog diameter difference into a promised change in loaded deck height. Truck Tire Load Capacity and Inflation Pressure: Key Differences On this sheet, the lower-profile LS669 is also the version with the lower maximum-load entry. We would not sign off that difference without the actual vehicle requirement and the relevant load-and-inflation information in front of us. The pressure cell alone cannot establish equal load capacity. The terminology is covered separately in LANDER’s guide to truck tire load ratings. For this order, keep the discussion on the two specifications actually being offered. What Would Make the Enquiry More Useful? An enquiry headed simply “385 tires” leaves too much to discuss later. Our preferred format is a separate entry for each size, a quantity against each entry, and photographs showing the existing tire and wheel. A note identifying the vehicle and wheel position can accompany those photographs. The rest of the enquiry can describe where the tires will work: the route, road surfaces, usual load and destination market. When the quotation comes back, does it include the current sheet for the tire offered? If the supplier has proposed a different size, ask them to identify it in the reply. Approved wheel information belongs with that response. With those questions answered, the buyer can work through the price, packaging and documents. We would retain the correspondence in the order file; the reason for accepting a substitution should be available to the next person who reviews it. Where Does LANDER Fit into the Purchase? Qingdao Lander Sky Tyre has focused on truck, OTR, industrial, agricultural and forklift tires since 2013. The LS669 is a regional TBR option, and its published data allows these two sizes to be compared without guessing the missing specification fields. For a quotation, send LANDER your requirements, including the size, quantity, operating route and market. Ask for the current sheet for the version being quoted. Where a size change is involved, keep the vehicle manufacturer’s fitment decision in the purchase file as well. Conclusion Two prices are easy to compare; two fitments take more work. In this LS669 example, we would return to the rim entries and maximum loads before choosing between the offers. Once the technical review is complete, file it with the order. That gives the purchasing team a record of why it accepted the quoted 385/65R22.5 tires or 385/55R22.5 tires. FAQs Is a matching 22.5-inch rim diameter enough for replacement? No. The diameter may match while the wheel width or contour is unsuitable. An approved wheel pairing does not remove the need to review clearance and the vehicle’s load requirement. What is the outside-diameter difference in this example? The two LS669 catalog diameters are 1,072 mm and 996 mm, so there is 76 mm between them. It is a comparison of these catalog entries, not a replacement approval. Does the LS669 load figure stay the same with the lower profile? No. Against the 385/65R22.5 entry, LANDER lists 5,000 kg. Against 385/55R22.5, it lists 4,500 kg. Those are the figures for this particular model. What do 65 and 55 mean? They give nominal section height as a percentage of nominal width. Both sizes have 385 mm as their nominal width. Which standard rims does LANDER list? For these LS669 entries, 11.75 goes with 385/65R22.5; 12.25 goes with 385/55R22.5. Ask separately about other approved rims. What does LANDER need for a quotation? The size and quantity, plus the market and route conditions. Include certificate or packaging requests with the enquiry.
