Trust me not the tire brand they are great tires---its the Kenne Bell 2.8L making more HP in the cold weather even once I heat them up they still just not wide enough. So the question is on stock R/T classic rims how wide can I go in back--I put stoptech brakes on and had to put huge offsets on to clear the front so I have plenty of spacer to play with in rear. The rims are the 20 inch I believe they are 8.5 inches wide we meaured them. Can I get 305 35 20 on it????
