Question

Back in 1997, my wife and I drove from Ft. Collins Colorado to Fairbanks Alaska. The temperature when we left Ft. Collins was 70^oF, and the outside pressure was 850mb. The tire pressure was about 30 psi (pounds per square inch). On arrival in Fairbanks, in late October, the temperature was a balmy -25^oF and the atmospheric pressure was 1000mb. If the tires did not leak at all during the drive, what would have been the tire pressure reading upon our arrival in Fairbanks?
