My personal rule is... street tyres on the highway... measure pressures cold....after an hour or two on the highway they have raised 1-2 pound. More than 2 pound they need more pressure.. ie, they are getting too hot. At the race track tyres will work harder so start 5 pounds lower cold. Street tyres only.
