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. 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 markings, the greater the elastic deformation of the markings on the ground, and the roll resistance caused by the loss of the elastic hysteresis of the forklift tires will also increase. Deeper markings are not conducive to the heat dissipation of the tires, and accelerate the rise of tire temperature. The roots of the markings are easy to tear and fall off due to severe punishment. Too shallow markings not only affect its water storage and drainage capabilities, but also simply cause harmful "water skiing", and it also highlights the disadvantages of light tread tires that are easy to slip.
Therefore, it is not good whether the markings are too deep or too light. The objective law is that the markings will become smaller and smaller during use. In order to ensure the effectiveness of the streak effect, countries around the world have formulated clear regulations on tire streak wear limits. And die-engrave the tire wear limit warning symbol "" or (and) the English symbol of "TWI" at several equal parts along the circumference of the tire shoulder. When the convex surface of the pattern block is worn about 1.6mm (1/16 inch) from the bottom of the pattern groove, the markings at the symbol have 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.
