Need to re-pressurize winter tire air pressure to summer

I had been driving 79 mph for eight hours, on my vacation trip to San Antonio from Montgomery, when tire pressure warning light came on. My immediate thought was a tire going flat.

I exited interstate and checked tire pressue. All four tires read 39 lbs. Then I realized the warning light may be warning me of high pressure, so I aired it down to 35 hot pressure.

The only thing I can think was winter cold tire pressure reads much higher at summer temperature, thus the need to repressurize winter/summer time.

Correct. A temperature change of about 8-10 degrees can equal about 1lb or so change in tire pressure.

per xysler owners manual 12'F = 1lb on the stock Jeep tires, so check pressures (cold) MORE often in the fall but, at LEAST 2x a month is good practice
