How Tire Pressure Affects Safety, Comfort and Efficiency

Correct tire pressure supports predictable handling, tire durability and efficient rolling resistance.

What to Consider

The correct pressure is the vehicle manufacturer's recommendation, normally found on the placard or in the owner's manual. Maximum pressure on a tire sidewall is not a substitute.

Practical Perspective

Pressure changes with temperature and load. Check when tires are cold and inspect for cuts, bulges and uneven wear.

Expert Perspective

NHTSA provides consumer tire-safety information covering tire condition, pressure and maintenance.
