Checking the Tire Pressures
Tire pressures depend on axle load and
tire size.
Tire Pressure Table
• The tire pressures shown in the
table apply to cold tires.
• Unnecessary tire wear is frequently
caused by vehicle operation with
tire pressures which do not match
the axle load.
• When twin wheels are fitted:
• Both tires must be inflated to the
same pressure;
• The tread depth must be practically
the same on both tires.
* The axle loads and corresponding tire
pressures shown in the table apply to
normal operating conditions. For all other
cases, refer to the specifications of the tire
manufacturer.
