22.1. Tire size designation
Because tire pressure affects tire performance and wear, tire pressure should be checked (see chapter 1).
If the wheel rims are bent, leaking air, broken bolt holes, severely corroded, missing vertical symmetry, or the wheel nuts cannot be tightened tightly, the wheels must be replaced.
Balancing wheels and tires is essential to ensure the desired handling characteristics of the vehicle. Unbalanced wheels adversely affect handling as well as tire life. Whenever a new tire is fitted to a rim, the wheel must be balanced.
