I have a new set of 35/17/17 mtr's. trying to factor in all variables to have proper pressure.
1: d rated tire
2: heavy jku , bumpers with tire carrier , sliders (all l.o.d.) winch
3: mounted on stock 7.5 rubi rims
Jeep rode fine with 30 psi, however, after 50 mile trip the tread was noticeably hotter on inside tread by touch. SO , i did the chaulk test .
Results showed hardly any wear on outer lugs. Things improved as i slowly aired down, however at 25 psi there is 3/4 in of non-wear on outermost lugs.
I am concerned with side wall heating up even without tire bulge.
I realize most of the problem is with the narrow rim.
My ? to the forum is at what point is lowering tire pressure counter productive to my setup and should i run a bit higher pressure at highway speed?
