Can the Port Tyres Still Be Used if the Pattern on Tyres Are Worn Down?

1. The importance of patterns on port tyres


The main function of the pattern on the port tyres is to increase the friction between the tread and the road surface to prevent the wheel from slipping, which is the same as the sole pattern. The tire pattern improves the ground contact elasticity of the tread. Under the action of the tangential force (such as driving force, braking force and lateral force) between the tread and the road surface, the pattern block can produce greater tangential elastic deformation.


As the tangential force of port tyres increases, the tangential deformation increases accordingly, and the "friction effect" of the contact surface is also increased, thereby suppressing the slipping or slipping trend of the tread and the road surface. This largely eliminates the shortcomings of non-pattern (light tread) tires that are easy to slip, making the performance related to the friction between the tire and the road surface-dynamic, braking, steering and driving safety normal, serving as a reliable guarantee. Studies have shown that the factors that produce the friction between the tread and the road surface also include the adhesion between the two surfaces, the effect of molecular gravity, and the micro-cutting effect of the small-size micro-protrusions on the road surface. However, the main role is still elastic deformation of tread blocks on port tires.


2. Can the port tyres still be used if the pattern on tyres are worn down?


Heavy equipment tires are generally composed of three-section rubber, supported by high-rigidity, high-strength base rubber and steel ring, which not only ensures the stiffness of the tire, but also ensures the tightness of the tire and the rim, and fundamentally eliminates the slippage of the tire. The highly elastic intermediate glue effectively absorbs the vibration generated by the vehicle.The thicker tread rubber layer of heavy equipment tires ensures the tire's tear resistance and abrasion resistance and improves the service life of solid tires. The crown is the tread pattern part, which is processed by natural rubber and has super abrasion resistance. Toughness and elasticity are the main contact parts with the ground during normal and safe operation.


There are obvious safety lines at the port tyres tread block and the transition part of the carcass. Generally, the tire can be replaced when it is worn to the position of 0.1-1CM on the safety line. At this time, the tread pattern should be nearly flat, and the tire grip will be significantly reduced. Safety hazards such as skidding and failure to stop the car are easy to occur. At the same time, the tire elasticity will be obviously insufficient, resulting in increased body turbulence, and damage to the front and rear axle housings will increase maintenance  costs.
