Air Pressure Of Tire

The weight of the vehicle flattens the tire's contact patch. When the tire rolls, this results in deformation all around the circumference of the tread and the entire belt assembly. With low pressure, there is a greater deformation which results in more intense warming and greater rolling resistance. This all results in a greater wear and a greater safety risk.

Example: Specified series production tire pressure depending on load on cold tires.

Air Pressure (Bar)	Air Pressure (%)	Service Life (%)
2.3	100	100
1.9	80	85
1.4	60	60
1.0	40	25

Excessive air pressure leads to greater wear at the center of the tire and reduced rolling comfort. It is recommended always to maintain the air pressure indicated by the manufacturer.

NOTE:

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.
