What are some facts about tire pressure?

1. The tire pressure will vary with temperature by about 1 PSI (0.07 bar) for every 12°F (7°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure.

2. A tire “naturally” loses about 2.9 PSI every 3 months.

3. An underinflated or overinflated tire is not only dangerous because its blowout risk, but because the vehicle was designed with a specific operating tire pressure in mind. Underinflated or overinflated tires increases instability, reduces traction and increases tire wear.
