5 Key Notes for Warehouse Forklift Polyurethane Tire Replacement

Forklift operators usually focus on motors, masts and forks to avoid equipment downtime. However, warehouse forklift polyurethane tires are easily overlooked, yet they greatly affect driving stability and operational safety. Worn, chipped or cracked tires will cause deviation, abnormal noise and accelerated component damage if replaced improperly. Follow these 5 key precautions for replacing worn forklift tires.

Confirm tire model and load parameters Verify the original tire diameter, width, hub pitch and rated load before replacement. Polyurethane tires come with different hardness levels. Low-hardness tires offer quieter operation but lower wear resistance. High-hardness tires feature better durability and suit high-frequency working conditions. Mismatched tire specifications lead to difficult installation, insufficient load capacity and premature wear.

Check hub and bearing condition Do not install new tires directly after removing old ones. Carefully check the hub for deformation and rust. Inspect bearings for excessive clearance, jamming and abnormal noise. Installing new warehouse forklift polyurethane tires on damaged bearings causes uneven force. The new tires will wear out quickly, so faulty bearings must be replaced synchronously.

Keep consistent tires on the same axle Two tires on one axle must be identical in model, hardness and wear degree. Different tire specifications result in unbalanced rolling resistance on both sides. This causes forklift drifting, stiff steering and accelerated wear of tires and masts. Always replace tires in pairs instead of single replacement.

Install in place and fasten bolts with standard torque Clean dust and burrs on the hub surface to ensure a flat fitting surface. Tighten bolts diagonally and evenly instead of fastening one side at a time to avoid hub skew. Follow factory standard torque values. Loose fasteners cause wheel shaking, while excessive torque leads to bolt thread slipping.

Test run and check ground conditions after replacement Do not start heavy-load operation immediately after tire installation. Test drive at low speed with no load to check for drifting, abnormal noise and vibration. Perform light-load trial operation after confirming normal driving. Polyurethane tires have limited anti-slip performance. Clean wet or oily warehouse floors to reduce slipping risks.
