what psi to run in 35s
#6
40 to 45 is way too high with tires that big. When you have that high psi in those tires you will wear out the middle part of the tire tread because it balloons out, so you will prematurely wear them out. Having a lower pressure will ensure that the whole surface of the tire touches the ground evenly. We keep ours just a couple pounds higher than the tpm on the hummer. I keep my 33's at about 30 on my cherokee. They last so much longer that way, and make sure to rotate consistently.

Would 42 psi on 35in tires be too much cause i notice extra wear on the edges when i had 35 psi i just got my tires Nitto Trail Grapplers about a month ago n i would love to perserve them as long as possible, i mainly do street driving. Im new too having this kinda of size tire the truck originally had mickey thomson mtz on same size but they were very worn out n they had 38 psi

This is how I so it.
Chalk the tires (about a 2" wide line all the way across the tread) at 36-37psi drive in a stright line for about 100 ft. Check the chalk and see if the chalk is worn off to almost the edges of the tire. If not rechalk and try it a few psi lower. Keep it up until you get even wear of the chalk line.
Remember this only works with your rig aligned properly!
