1.12.4 Maintenance (Tire Air Pressure)
The weight of the vehicle flattens the tire's contact patch. When
the tire rolls, this results in deformation all around the circumfer‐
ence 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

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.
