The CO2 test was on going for a few weeks. About as exciting at watching grass grow.
Tired of that I decided to spice things up a bit.
So I deflated my CO2 test tire from 40psig to 15psig. Then brought them up to 40psig with R-404a.
Then rolled it out in the sun and dropped a sheet of aluminum in front of the tire to act as a reflector to heat the tire up faster. Almost immediately the tire surface temperature jumped up 50F. The back side of the tire heated up 12F in about 5 minutes.
This translated to a 2psi pressure rise.
An increase of 5 to 6 degrees F on the shade side of the tire resulted in another 1psi increase. At the same time the sun side temperature had risen another 10F.
