Pirelli pro comp tire pressures / temps

From another forum I am on and thought would share for other novice tire guys.
Messing with bike set up before next month. Have Pirelli Pro Comp Slicks 180/55 rear 5.5 inch rim and 120/70 front 3.5 rim. Did some tire pressure and temperature tests. Pulled all air out of tires and actually into a vacuum. Filled with nitrogen to recommended cold setting of 31 front and 27 rear. Do not like my compressor due to the amount of moisture in the air. Temperature was 69 in shop as was tire temp. Installed Woodcraft tire warmers and on low after 1 hour temperature went to 138 rear at 31 PSI and 128 front at 35 PSI. Set warmers to high after hour was 170 rear at 33.5 PSI and 162 front at 37 PSI. On high setting the rims were getting heat soaked also. Goes to show how important pressure checking your tires is through out the day. Will be nice to have a good base to work from.
