I have 305/35/24 (which is like 33") and it doesnt rub and thats a 10" wide wheel. My bro has Mickey Thompson Baja ATZ LT325/50/20 (which 33" tall and 13.5" wide)and Im not sure on the offset on his 2000 silverado with a 3" body lift and his rub when its turned ALLL the way (and sometimes it will only rub if its on a hill or something)
Hope this helps
