I have a 04.5 LLY duramax. Stock with the tortion bars all the way. I just bought some 20x9.5 wheels and need some tires. I want the tall and as wide as I can get. I don't trust tire dealers, They play on the safe side. Help me out..

305/55/20 = 33/12.5/20 You may be able to get a 35" 305/60 tire but they will rub and the 305/55/20 look real, real good!

Just out of curiosity, What size were those toyo muds and wheels you where running?

315/75/16 = 35x12.50x16 They rubed bad I couldnt hardly turn out of a gas station with a heavy bump with out rubbing bad! I am very front heavy with the bumper though thats why I am sticking with 33 untill I get a 4" lift

These are 33x13.5x18 and no rub at all 4.5" back space at -12 offset
