I was wondering if there are anybody running 18" wheels with 325/60R18 tires on a 2500HD(8lug)? If so, do you ahve any pics of the m and how do they fit?

Check out this guy at fullsize.com here He's got a light duty 2500 w/ 325/60R18 Toyo a/t's on some eagles rims. IMO itis one of the best lookin tire/wheel combos i've ever seen.

 

That's gonna need a wide rim, I don't think an 8" will work...but it may. That tire is ~33" tall but it's going to rub the front bumper and stuff so mind that. You can see in those pics his is trimmed.

When I order my HD here soon (either May or Aug depending on when I can order an '05) I'm going to get some Weld Stonecrusher wheels to put on it in an 18x10" size and a 325/65R18 (~35" tall) Nitto. Those are going to require a 6" lift (I've decided on a CST) but it should be fine.
