I have an '81 F150 4x4. Currently I am running 31's on my truck and I'm wondering if 33's will fit with a 2.5 inch suspension lift. I know these trucks can clear 32x11.50R15's stock wil only minor rubbing. So I'm pretty sure 33's will fit with the 2.5inch lift but I want to make sure before I buy the parts. Any help is appreciated. Thanks!

 

you have to watch the backset on your wheels to make sure the tires won't rub the radius arms when turning hard. then you also have to watch how far out the tires stick to avoid having the fenders hit the tires when suspension is compressed during hard offroading.
