Tire temperature/measurements

[Gojira]

Should the tire pressure be measured when the tires are cold, or when they are hot? are the pressures posted on the door cold pressures?

Thanks!

Doesn't it say Cold Tire Pressure right on the door sticker?

They get higher when hot, so you bleed some off if you're going to keep them hot during an event and want less pressure. Then after the event I fill them back up for (cooler) road use.

Maybe I'm making this too hard..

For street driving, measure them when cold. Yes, the door sticker is for cold temps.

For track use, the hot temp is what is important. Many are using something close to 28PSI hot. Some use lower pressures for the fronts; like 26F 28R.
