Hey I just bought my first F-150 last monday. Its an '89 its bone stock and I just feel the 235's are just too small for my liking. I was wondering whats the biggest tire I could run without rubbing or hitting the top of wheel well when I hit a bump with having to get a lift?

 

Assuming you have a 4x4, 33's will only rub the radius arms at full lock if you space out the front bumper with washers or old lug nuts.

mines are 31's no rubbing anything and looks good for road truck, unless u want offroad look on it i'd also say 33's
or get wheel spacers and then the 33's think then it wouldn't rub anything
