Tire wear can be attributed to the following reasons: 1. Wear on both shoulders of the tread: If the tread shoulders of the car tire are worn, it may be due to insufficient tire pressure or vehicle overload. Additionally, insufficient tire pressure or overload can increase fuel consumption and cause the tire temperature to rise excessively, leading to a blowout. 2. Central tread wear: The main cause of central tread wear is excessive tire pressure. High tire pressure reduces the contact area with the ground, resulting in central tread wear. Excessive tire pressure can also overstretch the cord layers, potentially causing blowouts on uneven roads. 3. Inner or outer tread wear: Inner or outer tread wear may be caused by improper front wheel toe-in or abnormal wheel camber. Frequent sharp turns during daily driving can also lead to inner or outer tread wear. 4. Wavy or scalloped tread wear: Wavy or scalloped tread wear is generally caused by poor wheel balance, resulting in steering wheel vibration during turns and uneven tire wear. It can also be due to inaccurate front wheel alignment. Therefore, it is essential to regularly inspect the car's tires to avoid malfunctions and unnecessary losses for the owner.

I've been driving for over 20 years and have encountered tire wear issues several times. The most common cause is incorrect wheel alignment, where the wheel angles are off, leading to severe wear on the inner or outer edges of the tires while driving. Overinflated tires accelerate center wear, while underinflated tires cause faster wear on the edges. Additionally, aging suspension components, such as worn-out shock absorbers or loose bearings, can make the tires wobble and increase friction. Driving habits also play a role—frequent hard braking, rapid acceleration, or sharp steering in curves can all cause tires to wear out faster. I recommend checking tire pressure every quarter, getting an alignment adjustment annually, and maintaining smooth driving habits to extend tire life, save money, and ensure safety.

As someone who enjoys tinkering with cars, I've found that uneven tire wear often stems from mechanical parameter misalignment. For instance, incorrect toe-in (either too small or too large) causes tires to pull against each other, leading to uneven wear. Improper caster angles increase tire load during cornering. Tire-related factors like unbalanced installation or axle deformation can also cause vibration and wear. Repeated impacts from driving on uneven surfaces with potholes make the problem worse. Post-modification misalignment is particularly dangerous - I once installed wider tires without proper alignment, resulting in rapid uneven wear. Regular maintenance like checking tire pressure, performing wheel balancing, and choosing the correct tire specifications are essential to control wear.

I have dealt with many tire issues before. The main causes of tire wear are misalignment or abnormal tire pressure. Misalignment can lead to uneven wear, such as the inner side wearing out first. High pressure causes faster wear in the center, while low pressure leads to wear on both sides first. Suspension faults, such as loose bearings, increase vibration and also contribute to tire wear. Aggressive driving, like sudden stops and sharp turns, is equally harmful. Early inspection and maintenance are key.
