Can the Warm Actual PSI Inside a Tire Exceed the Cold PSI Rating While Towing
Question:
Hi yall . . . . Just purchased a new 2019 Ford F250 Superduty with 8 foot bed, 6.2L engine, 4.30 rear end, supported by Firestone RideRite Air Bags. The stock tires that came with the truck are Continentals, size LT275/65R18E 123. However, on the tire itself it states maximum tire pressure is 80psi cold. On the door post the sticker states front 60psi cold and rear 75psi cold. I have in the past on other trucks I have owned aired up the fronts to 65psi and the rear to 80psi. But on my last trip I just completed and living in Central California where the current temp is 95 degrees, my rears inflated to 90 degrees and the fronts to 68 degrees. Is this something I should be worried about and should I lower the cold psi in the rear to compensate for the heat. The trailer is a 2018 Grand Design Reflection 337RLS, current loaded weight is 12,220 pounds Combined vehicle weight is 19,270 pounds

Expert Reply:
The max psi rating that is listed on the sidewall of your tow vehicle's tires is while the tire is cold. Therefore, the actual psi while warm could very well exceed this. That is not cause for concern as this is taken into consideration when the recommended psi rating which is listed on the door jamb was created. Therefore, you will need to fill your tires to the recommended psi rating on the door jamb regardless of ambient temperature or the weight of cargo/trailer unless otherwise stated in your owner's manual.
