Huh, last I checked, my aam's were still 8 X 6.5 or 8 X 165.1mm. At least when I last looked at wheels for my truck.
Ok Rusty JC what is da facts here?
Feel free to punch in your exact vehicle on Tire Rack and it pulls up wheels for your vehicle. For my Truck (and I just did a 2015 in case there were any changes), it brings up a list of wheels and shows what bolt pattern they use. They were listing rims at 8 x 165 mm which is basically the exact same thing as an 8 x 6.5" wheel. Thinking about getting some wider tires for my truck (not really taller, just wider) so I get better flotation on sand. In order to run a wider tire on stock suspension, I need to have a rim with a shallower offset along with more width for the tires I'm interested in. My OEM 18" wheels are only 8" wide and have an offset of around 57mm. Most aftermarket 18" wheels that are 9" wide have 12mm, 18mm, or 20mm worth of offset. Enough to bring the entire wheel assembly 1" further away from the frame allowing wider (and taller) tires to be used on stock suspension and achieve full-lock with no rubbing. Seems like the tallest tires ran on our RAMs with the radius arms and all stock suspension is 35.1" after lots of searching on all the forums. Only needed mods are slight trimming of the fender liners at the bottom which I can live with.
For the curious, I'm particularly looking at 295/65R18 or 305/65R18 since they're roughly the same diameter as the stock 275/70R18's on a RAM. And if that's not enough, I want a rim widee enough to handle 35x12.5's or 325/65R18's which are roughly 1.5" taller.
