Well, I can add some real life temp results... Before an autox run, I set my front tires to 42psi. The tires were about air temp, so ~65F. After the run, I checked the pressure and it read 51psi. The tires I would say were about ~110-120F by the feel of my hand on them as I forgot my digital thermometer. So, a 9psi rise for ~45 degrees. 9psi is a pretty large increase imo.
