My 96 F150, with stock front suspension and 170,000+ miles and 31x15x10.50 tires does not rub, full lock or no. I do not know if the components were well taken care of before I bought her, or not. I have done nothing special other than routine maintenance.

 

You guys with 31s that don't rub, are you on the steel wagon wheels (8 spokes, rally wheels?) or the aluminum wheels?

 

15x8 aluminum with 4" backspacing.

 

i have 31/10/50 on my 87 f150 that rub the same spot

 

you running stock wheels

 

The stock aluminums are 15x7.5 right? I'm pretty sure that the wagon wheels and polished wheels are both 7.5 wide and same back spacing... Can anyone verify that for me?

 

Mine had stock steelies. Never measured them but I think they're 7 wide.

 

Yes 35" tires do rub the radious arm with out wheel spacers.

 

It's from the rim backspacing I have the same issue got aftermarket radius arms and still did it, did the spacers was reluctant but no issues after they were put on. Still don't like them but dealing with it

 

I have the factory chrome.
