RULE OF THUMB: The rule of thumb is for every 10 degrees Celsius change in ambient temperature, tyre pressure increases by approximately 1 PSI, even when not driven. While this doesn’t sound like much, remember that there is only 30-35 PSI in the tyres of passenger vehicles.
A few extra bars of air pressure can make a big difference to a tyre, and cause it to pop. Even in the event of that not happening, over-inflation can interfere with braking and cause premature wear and tear. (* PSI refers to the minimum amount of air pressure needed to support the vehicle at its maximum load.)
