Consistently checking and maintaining the correct tire pressure is fundamental for safety and performance, especially in winter.
Cold air is denser than warm air, causing tire pressure to drop approximately one PSI for every 10-degree Fahrenheit drop in ambient temperature.
Under-inflated tires can lead to poor handling, reduced traction, and uneven tread wear.
It is essential to check the pressure regularly when the tires are cold and inflate them to the specifications listed on the vehicle’s doorjamb placard.
-
Install as a Complete Set of Four
For optimal safety and vehicle stability, winter tires must always be installed in a complete set of four.
Installing only two winter tires on the drive axle can create a dangerous imbalance in traction between the front and rear of the vehicle.
This can lead to unpredictable handling, such as oversteer or understeer, particularly during emergency maneuvers or on slippery surfaces.
A matched set ensures that all four corners of the vehicle have similar grip characteristics, preserving the vehicle’s intended handling dynamics.
-
Adhere to Seasonal Changeover Schedules
The soft, flexible compound of a winter tire is not designed for warm weather.
Using winter tires like the Snow Claw in temperatures consistently above 45F (7C) will cause the tread to wear down very quickly.
To maximize the tire’s lifespan, it is crucial to install them when cold weather arrives and remove them once the threat of winter conditions has passed.
Proper timing for this seasonal changeover preserves the specialized tread compound and ensures the tires are ready for subsequent winter seasons.
