I recommend 9" max wheel width with 5.5"-6" backspacing. The less the backspacing, the more it will stick out.

my personal preference is 5-5.15" BS, but if you're gonna be running 35's without 3.5"+ of lift you should stay closer to 5.5" BS, to avoid rubbing.

wow, I bet you wish you had a nickle for ever time you have pumped out this piece of info!

I had to run 5.98" of backspace to make my 35x12.5's fit. ( on a 9 " rim) They tried to put on the 5.39" BS rims & they rubbed both front & rear of the fender opening.

Yup, she's leveled and the 305's I'm running are around 33 x 12.50. Wheel offset is the distance from the centerline of the wheel to the mounting surface on the back of the wheel. Wheel width and backspacing are generally more useful #'s to go by.

Like Pauly said, 9" max in width and somewhere around 5.5" to 6" backspacing are ideal.

Thank you

Running 16 psi up front and 13 psi out back. Although the picture doesn't show it, the beach with truck access here has some very soft sand, especially up by the entrances, the area be the inlet has a much firmer sand layer. Running a low pressure lets the truck "walk" right through all the marshmellow fluff we have.

In theory, yes.... Backspacing combined with overall wheel width.

Should be good, a 8.5 wide wheel with 5.5" backspacing is pretty much perfect.
