When cold my tires should measure 30 psi according to the label on the door. After driving for an hour what psi should they measure? Is it possible to get a close to accurate reading?

Tire pressure after driving?

Sure.. After driving for an hour, use your tire gauge and measure the pressure. Really!
You know darn well that the pressure will go up with temperature, and that temperature will go up with driving. And then, when the tire cools, the pressure will go right down again to the ambient temperature level.
Are you going to try to chase the temperatures and pressures up and down constantly?? Get anal about something that really matters.

Pressure after driving would involve knowing the temperature of the road you were on, how fast your were going, how hard you were braking and turning,the outside air temp, if the tire(s) were in balance and aligned and how old they are and if you had extra weight on them for the rears.. All of these factors influence heat build up to some extent. But a gain of 2-6lbs is a likely normal gain for most tires.
