Correct tire pressure is important for off-road tire performance, vehicle handling and safety. Both underinflation and overinflation can affect tire performance and may contribute to tire damage.

Tire pressure should be checked regularly, preferably when the tires are cold, and adjusted according to the vehicle manufacturer's recommendations.

Why Correct Off-Road Tire Pressure Matters

Both underinflation and overinflation can significantly affect tire performance and tire integrity, but in different ways.

Underinflation

Insufficient tire pressure can cause an abnormal rise in operating temperature, which may lead to irreversible damage to internal tire components and tire destruction from rapid pressure loss.

Overinflation

Excessive tire pressure can cause rapid and uneven wear and increase sensitivity to road hazards, including tread damage and casing breakage.

How to Check Off-Road Tire Pressure

Check tire pressure when the tires are cold whenever possible. If pressure is checked after driving, the tire is considered hot and should be adjusted according to the manufacturer's recommendations.

Never deflate a hot tire. Tire pressure increases as temperature increases.
Maintain equal pressure between dual tires.
Continue regular pressure checks with nitrogen inflation. Nitrogen inflation does not reduce the recommended pressure-check frequency.

How to Find the Correct Off-Road Tire Pressure

The correct operating pressure depends on how the tire and equipment are being used. A Michelin representative or authorized professional can determine the appropriate operating pressure based on factors such as:
