I'd like to know the formula for calculating that. I have a couple duallys and it burns me the lack of tire availablity in larger sizes. Right now I have 255/85s on my 97 which has 16x6 rims, according to all the literature I could find that is one size too wide for the rim, but it's been fine. Yet I've seen trucks with 38/11 boggers on what look like stock rims, and I just saw a mid 90s dually with 37/12.50/16.5 military tires on stock rims, they looked dangerously wide, but the guy says he tows heavy and hauls weight without a problem. Scares me, especially since the 16.5 rim doesn't have the safety bead to help keep the tire on.
