Tire pressure question
On my dodge dually drw door placard it says max cold psi 65 on rear. That's what I tow at. However tires are rated 80psi. Should I use 80 or 65? After a recent long trip had a blowout,not while towing.

- Thanks for advice will continue to use 65. Thanks again
- When it states cold pressure it usually means at 70 degrees. The pressure will normally go up based on air temperature not necessarily road temperature. My truck also says 65 rear and tire says 80. I set mine at 80psi and when it's 70 degrees. This afternoon it was 95 degrees and driving at 65mph I checked them at a rest stop and were 90psi and sidewall was 124degrees measured with a infared gun. According to tire manufacturer spec this is all normal.
- 80# is max tire load rating for 'single' application..not dually. Stick to the 65#
- 65. Tires will heat up when on the road and tire pressure will increase. Besides, the more pressure in your tires (reaching the tire max), the harder and bumpier will be the ride, and when towing (anything) with very hard tires, it's just simply NO fun at all, unless you enjoy headaches and your back bone yanked out of joint from all the hard bouncing.
