Question 17x9.5 backspacing

I know a 5.5 is optimal..but I ran across a brand new set of 17x9.5 rims with +32mm offset..which I believe breaks down to a 6.5in backspace. Would these work on the back of a 69? Maybe with spacers? They are cheap enough I'm thinking about buying em just to resell them..be nice if they would work and not be tucked in to far..

Re: 17x9.5 backspacing

6.5" will hit the inner wheel well before it even bolts on. 5.5" actually touches in some situations.
1" is a little much for a standard spacer. You'd have to get those billet spacer deals that cost near as much as a wheel.

Re: 17x9.5 backspacing

I have 17" x8 Boyd Cottington smoothies on the rear of my 69,and the back spacing is 4.5.If i make sharp turns,or on very un-even terrain,i can hear a slight rub on the rear tires.I checked the outer sidewalls for scrapes,but there were none,The rubbing seems to be coming from the inside sidewall of the tire.In my opinion i wouldn't go bigger than a 4.5 offset.

Re: 17x9.5 backspacing

A +6 offset is optimal on a '69 so no matter what width wheel you use you can fit the widest tire by using the backspacing that equals +6. This holds true for 15x7" rally's w/ 4.25"bs (factory 15" Z/28) to 17x9.5 w/5.5"bs...

See the chart, find your wheel width and +6 to see what bs to get...

A 17x9.5" w/6.5"bs would require a 1" wheel adapter and that would most likely offset the cost savings of the wheel itself. A spacer is placed over the studs and sits between the hub and wheel, an adapter is much safer and bolts to the studs on the hub and has a second set of studs the wheel bolts to.
