Why You Really Need W i n t e r T i r e s
Though anti-lock brakes, traction control and vehicle stability systems help make it easier to utilize a tire’s full potential, none of these systems actually provide more traction. They are only able to assist with vehicle acceleration, braking and cornering capacity based on the traction provided by its tires.
Anti-Lock Brake Systems help prevent sliding tires by selectively releasing pressure to pump the brakes. While anti-lock brake systems help maintain steering control and directional stability, stopping distances may be longer in winter conditions. Traction Control helps prevent spinning tires by reducing the engine's power and/or applying the brakes. Traction control also helps maintain directional stability, but acceleration may be slower. Vehicle Stability Systems help maintain control by sensing when a vehicle deviates from the intended course (determined by speed, cornering, and steering inputs) and selectively braking individual wheels and/or reducing engine power. Unfortunately, none of these sytems can rewrite the laws of physics or exceed the capabilities of the vehicle's tires. Four-Wheel Drive cars, SUVs and light trucks are often purchased because their drive lines make winter driving easier by dividing the engine's power between more tires to provide an advantage when accelerating on slippery roads. Doubling the driving wheels virtually doubles the acceleration on slippery roads. Doubling the driving wheels virtually doubles the acceleration on slippery surfaces. However, four-wheel drive doesn't offer any unique advantage when the vehicle has to stop or turn since every vehicle uses all of its tires to provide braking and cornering traction. Tread Depth
Why Too Little is Never Enough Tires need more tread depth in winter conditions to compress snow in their grooves and release it as they roll. If there isn’t sufficient tread
depth, the vehicle’s traction and mobility in snow will be reduced. Fortunately, Winter tires are typically molded with deeper tread depths than summer or all-season tires.
Tire Air Pressure The Effects of Time & Temperature Tire inflation pressures change due to time and temperature. Tires lose about 1 psi per month due to air escaping through the rubber as it stretches. For each month AND For every 10°F change in that passes, you ambient temperature you LOSE 1 PSI LOSE or GAIN 1 PSI Be Ready with a WINTER TIRE & WHEEL PACKAGE!
Tire Rack's Winter Tire & Wheel Packages make changing to winter/snow tires easy and efficient.
With winter tires mounted on their own wheels, you can install a seasonal package yourself. When the weather changes, you're ready. When the seasons change again, your summer package goes back on just as efficiently. 


Benefits of Buying a Package
~ High quality, vehicle-specific, exact fitments
~ Package arrives ready to bolt on your vehicle
~ Switch seasonal packages at your convenience
