I am running 235/75/r15 on both of my explorers but my questions is what pressure do you guys run with that size tire on 15x8 rims ??? Cause I am having problems with wearing the outside tread out ..
Here is the tire I am using
That tire has profile blocks that cover a part of the sidewall, so stiffens it , and leaves less sidewall to flex.
I suspect the Firestone tires that courced the Ford Explorer/Firestone affaire, in wich more then 100 people died because of roll over accidents, mostly courced by blowing tire, to have such kind of profile too.
Those tires need higher pressure to give it lesser deflection.
This is all my own conclusion.
In the affaire 26 psi was used all around, and later highened to 30 psi , so probably that 30 is enaugh to cover the lesser deflection allowed.
But to be shure you have to calculate it.
Nothing wrong with these tires , as long as you use high enaugh pressure, wich lower the comfort and gripp though.
That needed tire -pressure can be calculated, but the given maximum load of the tire then needs to be lowered , mayby even by 10%.
Will show 2 pictures of such a tire in compare with a "normal" road tire, and an even worse off-road tire that needs even to substract 20% of the maximum load.
This is the compare and now the tire with even larger sidewall flexing reduction wich needs probably to reduce that 20% of the maximum load.
