Tire pressure also affects wet weather performance!
The air pressure in your tire supports the weight of your vehicle (not the sidewall of the tire). Thus, it significantly impacts tire performance, regardless of the weather. When your tires are at a proper tire pressure, they provide even distribution of a load across the contact patch, stabilizing the structure of the tire itself. Properly inflated tires have a maximized contact patch, giving the area of the tire that touches the road optimum contact for the best possible traction and handling response.
Underinflation:
Underinflated tires do not have enough air pressure to support the center tread area or the sidewalls. This forces the shoulders of the tire to support the weight of the vehicle. If the air pressure is low enough that the sidewalls do not have sufficient support, steering response and handling are compromised with a potential risk of sidewall damage.
Overinflation:
Overinflated tires will balloon out, shrinking the contact patch and forcing the center tread area to support the vehicle's weight. When the contact patch shrinks, less rubber makes contact with the driving surface, reducing the tire's ability to grip the road.
Overinflation and underinflation can cause irregular treadwear, reducing a tire's life expectancy. Overinflation causes irregular wear in the center tread area. Underinflation typically leads to irregular shoulder wear. It also increases rolling resistance, making it less fuel-efficient.
For the best possible tire performance in dry (or any weather) conditions, we suggest referring to the vehicle manufacturer's recommended air pressure which will provide the best wear and handling conditions for your tires.
Proper maintenance and air checks are important facets of safe driving and vehicle ownership. America's Tire not only teaches you how to check tire pressure, but also offers complimentary tire inspections and air checks!
