our hemi had 3.55 no spin on the option sheet but it has 20's.....can anybody figure that out? It's a lone star edition, so i dont know if it's special or not (i assume it is). And I was told the tires are 31", but theres no 5" sidewall on them tires....(ok maybe there is..it dont look it)..more like 3-4" is my guess. Somewhere between normal sidewall and the amount of sidewall those cars that do drifting have. LOL.
