Inflation Pressure
It’s important to maintain the correct inflation pressure in your tires as under-inflation or over-inflation may lead to a tire failure. The correct inflation pressure of your tires is specified by the vehicle manufacturer and is typically shown on the vehicle door ledge or in the owner’s manual.
Tires may lose air over time due to the permeability of rubber so it is important to check your tire pressure regularly, at least once a month including the spare. Ensure to check the pressure when the tires are cold (i.e. have not been driven on).
