Tire Wear Diagram. Tread wear the tread depth on each tire will be governed by two 2 tread wear alert values. You can also check your tread depth with the 20p test.
Inward tilt is negative outward tilt is positive. Diagram of the vertical contact pressure and tire slip quantities. This is different from toe wears symmetrical wear pattern.
As an example a tire on a steer axle on a motor coach will require a greater tread depth than a tire mounted on a tag axle on a motor.
The easiest way to find your tires measurements is to check the sidewall of the tire which you can do without taking the tire off. Putting a 20p coin into the grooves of a tyre is a simple way to test whether the tread depth is above the legal limit. Diagram of radial tire parts and wear signs to some the casual observer all tires look the same. The actual values will depend upon the type of axle on which the tire is mounted.
