Help your tyres keep their cool… even when they are hot
The brakes generate an enormous amount of heat (braking from 100 mph to zero generates enough heat to boil a litre of water) and can literally get red hot under heavy use.
Tyres get hot on long-distance and high speed journeys, and the heat increases the tyre pressure. Would it make sense to reduce the pressure slightly before a long/fast trip, so the extra heat simply restored them to the recommended pressure level? Pima Pumsi
No. Definitely and absolutely no. Lower pressure might partly and briefly “compensate” for heat expansion, but it will also generate even more heat! Even to the extent of causing a blow-out if the tyre casing has a weakness.
