Tire Inflation Tips

NOTE! Tire pressure must always be measured from cold tires.
Temperature has a significant impact on tire pressurization. The temperature inside a warm garage can be higher or lower than outside. If the tire pressure is measured inside, it may not be correct for outside temperatures.
Example: The temperature in the garage is 68˚F, while the outside temperature is 14˚F.  If the pressure is adjusted in the garage, the pressure added to the tires must be 4 PSI higher than the recommended value to ensure a correct pressure level outside.
The impact of temperature on the pressure of a car's tires is approx. 1.5 PSI for every 18˚F.
In addition to correct tire pressure, drivers should also ensure that uni-directional tires are correctly installed on the car. The arrow on the sidewall indicates the rolling direction.
To prolong the lifetime of the tires, front and rear tires can be changed from one axle to another every 3,000-6,000 miles.  As a result, the tires will wear evenly and show smaller differences in wear.
We recommend that you break in your winter tires by avoiding rapid acceleration and hard braking during the first 350 driving miles. A gentle break-in improves the durability of studding: the studs will fit securely into place and stay on the tires.
