On the front wheels, slightly more wear on the edges of the tires than in the middle is normal, and due to the inclination of the road, wear on the edge of the tire, which is closer to the center of the road (left wheel is outside, right wheel is inside), may be stronger.
Uneven tire wear is primarily the result of too low or too high tire pressures, and can also indicate poor front wheel alignment, shock absorber performance, wheel imbalance, or disc warping.
First of all, you need to monitor the pressure in the tires. The pressure should only be checked when the tires are cold. Pressure can rise noticeably when tires heat up from fast driving, so under no circumstances should pressure be bled from hot tires.
With increased pressure, the middle of the tire wears out more, i.e. due to high pressure, it becomes more convex.
With reduced tire pressure, the edges of the tire adhere more strongly to the road, and its middle is concave inward. Because of this, the edges of the tire wear out more. Tire pattern wear in the form of teeth is usually the result of overloading the vehicle.
Incorrect front wheel alignment and imbalance give typical tire wear patterns, which are described in the section «Troubleshooting» this chapter.
