Rules for tire care (BMW 5 Series E39)

It is generally believed that tires, so to speak, have a "memory," and rough handling - which is considered to be a quick or frequent collision with a curb or kerb - often leads to tire damage only much later.

Tire cleaning

If possible, do not clean tires with a steamer. If you hold the nozzle with a stream of steam near the tire, the rubber layer will be destroyed within a few seconds, especially after subsequent treatment with cold water. A tire cleaned in this way should be replaced for safety reasons.

A tire that has been in contact with oil or grease for a long time should also be replaced. The tire at the appropriate place first swells, but then returns to its original shape and appears to be undamaged. However, the load-bearing capacity of the tire is reduced.

Tire storage

Tires should be stored in a cool, dark and dry place and, if possible, in a relaxed state.

They should also not come into contact with oil or grease.

Tires should be stored in a garage or basement, lying down or mounted on a rim.

Before removing the wheels, you should increase the tire pressure slightly (approximately 0.3-0.5 bar).

For tires with a winter tread pattern, use your own rims, since remounting tires on the same rims is not economically viable.

Tire running-in

New tires have a very smooth surface from the moment they are manufactured. Therefore, new tires (this also applies to the spare tire) are subject to running-in. During the running-in process, due to the onset of wear, smooth surfaces become rough.

If the vehicle has a mileage of up to 300 km with new tires, you should be especially careful when driving on wet surfaces.
