I was thinking of getting bigger tires, what size can i do on the 15" rims?

 

my buddys is running 33 10.5 r15s and he has no problems with tire rub or any of that stuff
it makes his broncho sit up higher then stock

i am running 31 10.5 r 15s on my 94 silverado and i have no problems with tire rub or hiting any body panels when my suspensions bottoms out
