Many forklift truck drivers are concerned about the standard of tire replacement. The normal service life of forklift tire is 4 to 5 years, because the tread rubber will be aging over time. After 5 years even if the tread wear is minimal, it is best to replace it, because many small cracks are the cause of tire burst.
The service life of forklift truck tires varies with the rubber formulation, vehicle environment and driving habits. Therefore, the driver should pay more attention when driving, because there are also signs of forklift tires aging. For example, the aging parts of the tread are mostly from the edge of the tire or tire shoulder. Exposing to the sun and rain occasionally will cause small looped cracks on the rubber surface. These cracks indicate that the bearing capacity and quality of forklift tires have begun to decline. Forklift tire replacement in advance is needed in order to reduce the risk of tire burst.
Some forklift trucks will indicate the real-time wear status of the forklift tires. For forklift tires without wear marks, they can also be measured with calipers (or special forklift tire tread rule). Forklift tires are also subject to natural wear, so the tire of forklift company will mark the wear limit on the sidewall before the tire leaving the factory. Generally, forklift truck tires with groove depth less than 1.6 mm can no longer be used, because the drainage performance and puncture resistance of forklift tires will be greatly reduced. In addition, if a forklift tire has been repaired three to four times, the forklift company would recommend you to replace the forklift tire with a non-driving wheel or rear wheel to reduce the risk of tire burst.
