Re: Pressure for larger tires.

I found that the max tire pressure is designed for max weight load of the tire. The Bridgestone Duellers that came from the factory on my truck had a max of 44psi with a recommended pressure of 35psi. The tires max load was 2535 at 44psi, and the new tires have a max load of 3195 at 65psi. I calculated the tires daily average load by dividing 2195 by 44 and multiplied the result by the manufacturers recomendation of 35 and get 2016 pounds. For the larger tire, calculate the same at 3195/65=49.15 x (?) = 2016 or 2016/49.15=41psi.
