Any type of tire product has its own tire pattern, and forklift tires are no exception. The tire pattern is very important to the tire itself. It plays a great role in improving grip, reducing noise and increasing drainage. Like tires, there are many types of tire patterns, including longitudinal patterns and lateral patterns, vertical and horizontal patterns, mud and snow patterns, cross-country patterns, etc. Let's take forklift tires as an example to explain the effect of pattern depth on forklift tires.

The deeper the tire pattern, the greater the amount of elastic deformation of the block on contact with the ground, and the roll resistance caused by the loss of the elastic hysteresis of the forklift tire will also increase accordingly. The deeper pattern is not conducive to the heat dissipation of the tire, and accelerates the rise of the tire temperature. The root of the pattern is easy to tear and fall off due to the severe punishment. The pattern is too shallow not only affects its water storage and drainage capabilities, but also simply causes harmful "water skiing", and it also highlights the disadvantages of light tread tires that are easy to slip.

Therefore, it is not good if the tire tread is too deep or too light. The objective law is that the pattern will become smaller and smaller in use. In order to ensure the effectiveness of the pattern, countries all over the world have formulated clear regulations on tire pattern wear limits. And die-engrave the tire wear limit warning symbol at several equal parts along the circumference of the tire shoulder. When the convex wear interval of the pattern block is about 1.6mm (1/16 inch) to the bottom of the pattern groove, the pattern at the symbol has been smoothed out, so a narrow horizontal strip of light tread is revealed to warn the driver that the It's time for the tires to be replaced.
