If you have aftermarket wheels with 4-4.5 of backspacing you will not rub with a 275. If you plan on using the stock wheels w/o a spacer 265s
285s will Rub and require trimming even with that lift.
I run a 275/70/R16 BFG KO and have an inch lift up front and have no rubbing.
thanks! Im going to use the stock sr5 wheels so I guess i should just go with 265?
Ya I would unless you plan on using spacers. Youll have to bump the wheel out like 30mm I think. Youll be safe with a 265.
