Air Pressure loss is an often overlooked reality.
This seems simple enough but beware of simple, there’s a bit more to it.
Misconception: The proper air pressure is what is stamped on the sidewall of the tire.
Corrction: The air pressure found on the tires sidewall gives the maximum allowable air pressure that the tire can withstand.
An individual should abide by the manufacturer doorjamb sticker, which will give the *air pressure recommendation that properly suits the vehicle.
*The stated air pressure is for cold air temperatures.
- Driving heats up the air inside tires.
- The environmental temperature also affects the air inside of a tire.
Taking this into consideration:
Add 2 pounds to 3 pounds of air pressure above the *recommended air pressure if tires have been driven on or have been sitting in the heat.
- If the tires are wearing on the inner and outer shoulders equally, increase the air pressure by 2 to 3 lbs. OR as necessary to correct.
- If the tires are wearing down the center: Decrease air pressure as needed until corrected. Continue to monitor.
