What Causes More Severe Wear on Front Tires Compared to Rear Tires?
2 Answers
Generally, in front-wheel-drive vehicles, the front tires bear the majority of forces during load-bearing, acceleration, steering, and braking, leading to faster wear compared to the rear tires, with a wear ratio that can reach 2:1. Below are the relevant explanations: 1. Tire Wear: During actual driving, tires undergo composite forces from driving and lateral forces, causing intense wear of the tire rubber. The rear tires, being non-driven wheels, experience relatively less wear, which is a normal condition. 2. Precautions: Typically, tires have a service life of about 5 years or need replacement after approximately 80,000 kilometers. The longer the tires are in use, the higher the risk of tread deformation and blowouts.
The front tires wear out faster than the rear ones, and I believe the main reasons are related to the car's drivetrain and steering functions. My car is front-wheel drive, so the front tires not only propel the vehicle forward but also endure greater friction during braking and turning. Every time I apply the brakes, most of the force is exerted on the front tires, causing them to wear down more quickly. Additionally, the car's weight is mostly concentrated at the front, such as the engine and driver's seat, which increases the burden on the front tires. Frequent starts, stops, and turns in city driving accelerate this issue. I recommend driving gently in daily use, avoiding sudden braking or sharp turns, and performing tire rotation every 6,000 kilometers to help distribute the load to the rear tires and extend their lifespan. Regular tire pressure checks and maintenance are also crucial.
