i have a 1994 f150 that i recently converted 4wd!!! i lifted it perviously 6 suspension and 3 body. i currently have 35s on back and 33s on the front. im gonna get a cheap used set in better condition than these. i wanna know how big i can go? i understand the radius arm rub and it doesnt bother me.

 

I'm not sure what the Max size you can run is, buy you better make sure they are all the same size/height. Running different sized tires front and back in 4wd will not work well.
