How much difference is there in the diameter and section width of a tire on different width rims? Tirerack says that a GY Wrangler Silent Armor 245/75R16C has a diameter of 30.5 inches and a section width of 9.8 inches when mounted on a 7 inch wide rim. How much, if at all, would those numbers change if mounted on a 8 inch rim? Any examples wouldn't need to be specifically that size. Just curious. |

Great! So, roughly a 1 % decrease in diameter and a 2% increase in section width. Thanks. That will come in handy. |
