Reduce Truck Tire Wear and Develop Good Habits

"Blowout" is a common problem when driving, and it is likely that all drivers have encountered it. The term “blowout” describes the situation quite accurately, as if the tire has been bitten. Definition-wise, a blowout is an abnormal acceleration wear on one or several inner or outer sides of a tire. One part of a certain tire wears out significantly faster than the other tires, causing uneven wear and rendering the tire unusable when inspecting big truck tyres.

Reasons for blowouts in big truck tyres

The primary reason for early tire wear is an overinflated tire

Appropriately increasing tire pressure can reduce the contact area between the tire and the road surface, thus reducing rolling resistance and fuel consumption. However, when the tire pressure is too high, it not only affects the tire's shock absorption performance but also causes the tire deformation to be too large, resulting in a reduced contact area with the ground. Normal wear can only be borne by the tread, resulting in early wear and tear.

Significant wear on both sides (shoulders) of the tire

The main reason for significant wear on both sides (shoulders) of the tire is insufficient inflation or long-term overloading. Low tire inflation or heavy loads will result in a larger contact area between the tire and the ground, causing the two sides of the tire to wear out and resulting in early wear and tear. If tire pressure is higher or lower than the rated value by 20%, mileage loss can be anywhere from 20-25%.

Uneven wear on one side of the tire

The main reason for excessive pressure on one side of the big truck tyres is misalignment of the front wheels. When the outward inclination angle of the front wheel is too large, early wear occurs on the outside of the tire, and when there is no outward inclination angle, early wear occurs on the inside of the tire.

To avoid blowouts, drivers should pay attention to their big truck tires in many ways to ensure safe driving

Pay attention to tire pressure

Tire pressure is vital, and both over and underinflation can shorten the tire's service life. Low tire pressure can cause the tire to deform and crack on the sidewall while folding, causing hysteresis movement. This leads to overheating, causes rubber aging, reduces fatigue of the cord layer and breaks the cords of the cord. Low tire pressure also leads to larger ground contact areas, accelerating tire shoulder wear. High tire pressure causes excessive tension on the tire cords, reducing the tire's elasticity, increasing vehicle load, and leading to cracking or explosion. High tire pressure can also accelerate crown wear and reduce the tire's resistance to piercing.

Regularly check the front tire's alignment

The alignment of the front wheels affects the tire's service life, especially the front wheel's beam and the front wheel's outward inclination. The outward inclination of the front wheel mainly accelerates shoulder wear, which is a type of uneven wear. Excessive or insufficient beam mainly accelerates inner and outer sidewall wear.

Pay attention to driving habits

In addition to handling situations, drivers should choose the road surface to avoid sharp objects such as stones, glass, metal, etc., which may puncture or scratch the big truck tires. Drivers should also avoid the adhesion and corrosion of chemical spills on tires. When driving on roads with pronounced arches, drivers should travel as much as possible in the center, reducing the imbalance of tire wear.

Avoid overloading

Under normal circumstances, an overload of 20% will reduce tire life by 30%, and an overload of 40% will reduce tire life by 50%. Turning rapidly, emergency braking, rapid acceleration, and high-speed starts will all damage the tires and should be avoided by drivers while driving.
