[ Are you sure the MT 315/60 won't work? Mine are 315/60's and are 30 inches tall and 12.5 tread with 14.5 section width.



how wide of rims are you using? m/t uses a 8.5-11 wide rim and they say the section width is only 12.9 and 11.9 tread. i ran 315's on my old dart... and i assure you that the 345/55/15's are at least 1.5 inches wider than a 315. the dart had the springs moved in to the frame rails and the 315's would rub sometimes. the 345/55/15's fit like a glove in my 69 plymouth...the 315's would look waayyy small compared to them. unless you are running them on a 12-14" rim?? is that even possible???

i dont know, the right size/ stance makes or breaks the car in my opinion, and i just want to fill the entire wheelwell, and i just don't want the same size tire on mine that will fit b body w/ stock wheelwells... does any of my rambling make any sense??



The 345 in the tire size designation tells you that they are 345 MM wide. So, the 315's are 30 MM narrower than the 345's.
