Volkswagen Touran Service Manual: Permitted Tread Depth - Variance

Volkswagen Touran Service Manual / Wheel and Tire Guide Information / Tire Wear / Permitted Tread Depth - Variance

For all four wheels use only tires of the same construction type, and tread.

Always use tires with the deepest tread depth on the front axle.

Replacing one individual tire is always possible. The vehicle manufacturer recommends at the very least however that the tires are replaced on both sides of the axle.

With sport differential on the rear axle, the vehicle manufacturer recommends always replacing the tires on both sides of the rear axle.

Note

The technical background of the limitations are thermal pressure for the transmission oil due to a large difference in the rolling circumference of the tires.

The Difference Between the Front and Rear Axle, must Not be Greater Than 3 mm.

Example:

Front axle left tire tread depth	Front axle right tire tread depth	Average front axle tread depth	Difference of the front axle to the rear axle
2.0 mm	2.0 mm	2.0 mm from left to right	3.0 mm
Rear axle left tire tread depth	Rear axle right tire tread depth	Average rear axle tread depth	Within the permissible tolerance
3.0 mm	7.0 mm (new tire)	5.0 mm from left to right
