| 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. |

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. |
