Im leveling my 2005 king ranch and i want to get 33" tires. right now i have 265/60/18's and the auto shop says i can get 325/60/18's. are they too big for my 18" stock wheels?

 

Yes. 325/60/18 is 13.5 inches wide. Your stock wheel i believe is 8 inches wide. Ideally, you dont want your tire to be more than 4 inches wider than your rim. you could put on 33/12.5/18, which would be very close to 4 inches.
