Does anyone know if these will fit a stock hieght 2005 gmc 2500hd 4x4. This is the wheel and tire size. 305/70 Mud Country Tires on DC-1 Wheels (16" x 8"), Bolt Circle 6 on 5.5

I'd say no,,, 28575r16 are as big as you can go on a stock truck..and your truck is 8 lug..

Then does anyone know of a good wheel and tire set up in this size (chrome). Thank you for your help

LT265/75R-16 will fit with no mods at all, as long as your wheels are close to the stock (+28mm) offset.

LT285/75R-16 will fit, but may require some torsion bar adjustments and possibly some trimming. You will also need 8 inch wide wheels (Stock wheels are 6.5'' wide).

Anything larger than 285 will require more mods in order to fit without rubbing.

Discount tire has the MB Predator wheel in Chrome as well as Brushed Alloy available with +25mm offset.

Many aftermarket wheel vendors stock wheels with ZERO and -12mm offset. These dimensions will put the wheel much further out than the stock location and will require a lot of trimming and T-bar cranking to make them fit. Also, the further out you locate the wheel, the more stress you'll put on the outer wheel bearings.

If you would fill out your signature with information about your truck, it will be easier for other members to help you out without having to ask every time.
