Default What PSI should I run?

I have 235/75/15 Goodyear All Terrain tires on my jeep. The tires themselves say maximum psi is 44 PSI. However, I want a softer ride and the tires to last. Would 25 PSI be a good PSI to run the tire pressure at?

i'd start at 35 then do the chalk test and adjust from there so you have a nice even contact patch

take a piece of chalk and draw a line on the tire. drive a little bit and see where the chalk is left. if its only gone from the centers your too high lower the pressure until its even no calk marks on the tread

25psi is a little low and will cause wear on the outer edges of the tread. 32psi offers a good balance of comfort and longer tire wear, I like mine at 35psi though.

isent that a stock size and the pressure on the side of the tire dosent mean **** its just the max pressure to run look on your drivers door their should be a loading tag and that will give you the correct pressure to run and if theirs none its 35 front and rear.. dont run 25 psi if you are looking to drive on a street it will overheat the tire and wear it faster then normal,chunking and uneven wear will occer. rember the ford exploders and firestone tires same thing

Follow the guidelines in your owners manual or look in your doorjam for proper pressures. 32-35 would be correct.
