Diagram 2
Tread depth over service life for vehicles with AWD and V tires.
P - Tread Depth
S - Distance Driven
1 - Front Axle
2 - Rear Axle
The diagrams presented cannot be applied in general.
They only illustrate the wear characteristics on the front and rear axles as well as wear characteristics of front and all-wheel drive vehicles.
Depending on operating conditions and chassis, the service life that can be attained may deviate substantially.
As can be seen in diagrams -1 and -2, for a given distance, more tread wears off tires with a complete tread than off tires which are quite worn. After the first 5, 000 km (3100 miles), no conclusion can be made about the total service life because the wear curve is not linear.
On FWD, the front wheels must transmit the major portion of the lateral and braking forces as well as the steering and traction forces. Due to these demands, the front tires on FWD vehicles wear more quickly than rear tires. Even usage of all tires is achieved by regularly exchanging front and rear tires. Rotating the wheels.
