Use the recommended cold pressure before long trips and during monthly inspection.
A sticker with the recommended tire pressure can be found on the door panel of your vehicle. Under or over inflation can affect tire lifespan, performance and increase fuel consumption.
Maintaining proper inflation pressure in tires is the single most important factor in extending tire life. Over and under inflation have negative effects on the tire by changing the tire’s footprint, which is the area contacting the road. When the tire is not contacting the road as design intended, the tread area will wear irregularly and therefore rapidly wear the tread surface. Likewise, it is air, not the tire actually carrying the load and absorbing shock. Any condition causing the tire to flex more as it is rolling down the road is causing heat buildup that can cause tire components and steel cord damage.
