Anyone Have 8.5" Wide Wheels with Stepside
 
I really hate to make another wheel thread. I spent hours reading wheel and Static Drop threads. I have narrowed down my plan to a 3.5/5 Static Drop and I really prefer the Look of 17" Wheels. I found a set of wheels that I do like that are 17X8.5 I can get these with a 4.75 Back Spacing. I can play with Spacers if need be a little, But Wondering if I can fit an 8.5" wheel all around (Specifically in the front). I dont believe the Back is an issue. I do Have the Narrow Rear Axle so I will likely incorporate a spacer back there already.

Optionally I can get a 17X8 with 5.5 Back Spacing. But Iam thinking that would require Larger spacers All around.

I havent picked out tires yet, but I am leaning towards a 28" Diameter. I dont mind keeping all 4 Tires the Same Width and Height.

Does anyone run a similar setup on a stepside? Ive seen alot of 8" Wide Wheels. Possibly someone has an 8.5" width up front in a 17" or maybe even a 20" wheel?

Thanks.

When I bought my stepside '68, it had 18x8 rims on it with 5" backspacing. The tires were 255/55/18. The insides of the tires rubbed on the bed sides when cornering, and that was even with a wider 1970-up rear end.

As low as my truck is in the front I should have ordered 245/50/19, it just barely touches a fender bolt when turning if I hit a bump.

Rears clear perfectly though. It’s a 67 (narrow) 12 bolt with a 5 lug swap for the CPP big brake kit. 4.5” backspace is perfect, 4.75 would be cutting it a little close with a narrow rear.

20x8.5 - 255/45r20 Narrow rear, 4.75" BS.

At the time it was around 5" rear static drop. I know people put bigger tires under the stepsides but just saying for me, I like to keep the wheel tucked under the fender a little bit.

This was measured with a Wheelrite, and I had an adjustable track bar. It's about as tight as I'd want to go on a stepside.

I have 17x8 with 4.5” backspace in the front and 17x9 with 5” backspace in the rear. In both cases, that is zero offset. meaning the wheel mounting surface is in the very center of the rim. (On an 8” rim that is measured between the beads, so overall width of an “8 inch” rim is 9” and on a 9” rim it is 10 inches so a 5” bs is zero offset).

In the rear the width of the tire matters and the rear axle. My truck is a 69 with a 71-72 5 lug axle swapped in which is 3/4 inch wider on each side. Otherwise the 9” rim in the rear wouldn’t work. FWIW, my truck is leaf spring and axle flipped for 7” drop.
