i have a 1990 f150 4x4 and i have 31X10.5 and they rub when i turn all the way to the left or right like is it just to big to run with out a lift? or is somthing of mine not right because i see these little rangers runnin around with 31X10.5 and i dont know how they can run them with out having issues

 

Where do they rub??

 

They rub on the radius arms and i think on little on the stabilizer bar aswell

 

Stock wheels or aftermarket?
If aftermarket, what size and backspace?

 

i got the factory steel rims on it

 

Have a similar setup, with the exception of 15x8 aftermarket rims. No rubbing problems here at all. 31x10.50 is a common tire upgrade for this vintage in this area.

How much front spring sag do you have???

 

i dont have alot but i think its time i get new ones pretty soon

 

Suggest to find some aftermarket rims that have a more outward offset, consider 30x9.50 tire, or just don't turn so tight! :-)~

I had an issue with the front spring sag - wearing the tires on the insides, and just looked goofy with the tires pulled in at the tops.

Found it was cheaper to replace the springs than to buy the necessary spring spacers. Doesn't look like yours are sagging too bad yet, though.
