| 18 × 7-8 | Cushion or solid tire | Compact warehouse forklifts operating mainly on smooth indoor floors. | Match the complete size marking and the specified wheel or rim dimensions; similar-looking sizes are not automatically interchangeable. | Check the tire’s marked load rating against the forklift maker’s requirements for the axle and wheel position. | Confirm the forklift model, front or rear position, wheel assembly, and required overall tire diameter. |
| 21 × 8-9 | Cushion or solid tire | Indoor counterbalance forklifts; use depends on the forklift’s original specification. | Compare the sidewall size with the existing tire or the forklift’s parts information, including the rim diameter. | Use the rating for the exact tire construction and size; do not infer capacity from tire dimensions alone. | Check wheel width, offset, clearance, and whether the forklift is designed for cushion or pneumatic-style tires. |
| 23 × 9-10 | Cushion or solid tire | Some larger warehouse and indoor counterbalance forklifts. | Verify the full size code and the required wheel assembly; size availability and construction vary. | Ensure the selected tire meets the forklift manufacturer’s required load rating for its position and service conditions. | Confirm that the tire does not interfere with the chassis, steering, mast, or other components through the full steering range. |
| 28 × 9-15 | Pneumatic or solid pneumatic | Forklifts specified for larger wheels and a range of indoor or outdoor surfaces. | Check the tire size, rim diameter, and approved wheel assembly; pneumatic and solid versions may differ in dimensions. | For pneumatic tires, use the specified tire and inflation pressure. For solid tires, check the marked rating and approved application. | Verify the original tire type, wheel fit, clearance, and any manufacturer restrictions before changing construction. |
| 6.00-9 | Pneumatic or solid tire | Common size format for certain forklift applications; suitability depends on the machine and axle position. | Read the complete sidewall marking and confirm the rim diameter and approved tire specification. | Check the tire load rating at the applicable pressure, if pneumatic, and compare it with the forklift specification. | Confirm the tire is approved for the forklift’s wheel, position, speed, and operating environment. |
| 7.00-12 | Pneumatic or solid tire | Used on some forklifts designed for a larger wheel and tire assembly. | Match the size marking and rim specification; do not substitute based only on a similar nominal diameter. | Check the exact tire’s rating and the forklift maker’s axle and tire requirements. The truck’s rated capacity is not the capacity of one tire. | Verify fitment for the exact forklift model, axle position, wheel assembly, and required ground clearance. |
