How is the Correct Tire Air Pressure Determined?

There is confusion amongst drivers of what air-pressure is the correct air-pressure in their tires. The tires say one thing, the owner’s manual says another. So, which is correct and why?

The air-pressure indicated on the side of your tire is the maximum air-pressure allowed by the tire manufacturer. The tire manufacturer’s recommendation often is far different from the vehicle manufacturer’s recommendation. The tire manufacturer bases their estimate on standards set by the Tire and Rim Association (TRA) without regard to the vehicle on which the tire is placed. The vehicle manufacturer bases their air-pressure recommendations on tires used on the vehicles while negotiating curves and straight runs. These tests are exhaustive and feature the loads created in turns at different speeds.

To get your air-pressures correct, bring your vehicle to Santa Maria Mazda. The importance of maintaining proper air pressure in your tires cannot be exaggerated.
