Can I run 15 x 8" SSII's all the way around or will I run into issues on the front ?
I currently have 245/60/14's all the way around on what appears to be 7: alum slots (Hard to measure with tires installed)

People have done it but a lot of it will depend on how your car sits. Health of the springs (stance) will matter.

JCervantes

Thanks, I was thinking if I kept to the 245/60R15 (Same size as the 14's but now a 15") I would be Ok. It sounds like what you are saying is the rim should not be an issue.

Depends on front wheel back spacing, I ran 15x8’s with 275-60’s on steelies on the rear, and 235-60’s on the front on 15x7’s, and the fronts rubbed the swaybar in a tight turn. This was when I ran stock springs.

Which 15x8 reproduction SS-1 wheel is correct, or better, for the rear of a '70 Cutlass - the model with a 5" backspace or 4 1/2" backspace? The 15x7 SS-1 wheel only comes with a 4.375" backspace .

IIRC, 4 1/2” is stock BS, 4.375 is close enough depending on tire size

anthonyP

Do you know if the 4.375 backspace will work on the front with 235/70-15 tires?

I am running 8" SS 1's purchased from Summit with 295/50R15 on the rear and 255/60R15 on the front. I cannot remember for sure but I think the wheels are made by Wheel Vintiques. I had some minor clearance issues on the front and trimmed a little off the left front fender wheel lip. I will probably step down a size when I replace the front.

That's a really tall front tire. I think most people who run a 70 series go 215 or 225

Sampson,
So you are saying you are running 8" on all 4 ? I want to make sure before I buy $400 in rims and find out they don't work.

Thanks Sampson !! I also like that deep dish look, I'm going for it

JCervantes

Sure I just talked to the guy, Now he wants to know what backspacing I need. I'm not a rim guru at all, Completely at a loss .... Can anyone help ? I want them to look good like Sampsons and not rub.

JCervantes

So He said 4.5 backspacing is standard, BUT there is a risk of some inside tire rub on tight turns against frame or sway bar ... What to do what to do ....

Sampson

I dug out the receipt from when I ordered mine. The back spacing is 4.5". Here is the link. https://www.jegs.com/i/Wheel-Vintiqu...34042/10002/-1

All I can add is I do not have any problems with tire rubbing on the frame or swaybar. I did have a minor issue with the left front fender on sharp turns in reverse. i trimmed it a bit and no problems since. As others stated spring height and condition plus tire size may come into play.
Good luck and I hope this helps.

Great looking Cars! Love the Anson Slots.

Sampson’s car is gorgeous, and looks like it sits kinda high, keep that in mind, I would run 245’s on the front, should be safe with 15x8’s..
Just my .02

anthonyP

Does anyone know if 235/70-15 tires on 15x7 wheels will fit in the front without rubbing on a '70 442?

dc2x4drvr

I ran 235-60’s on 15x7’s, had minor rubbing on my big sway bar, I think you’re good to go..70 series are slightly narrower.

Fun71

Actually, the 70 series are the same width but taller.

anthonyP

Will there be a problem with the height of 235/70-15 tires in the front of a '70 442?

Hard to say on a 50 yr old car
For example, Sampson's car look a little in in the front
