Tire and backspace question

There is a local guy selling a set of rims im interested in for my 68. The rim size is 17x8 and he says he has 275/40 on all 4 rims. From all my readings, I have seen its not ideal to run this size tire on a 8 inch rim. Second I cant picture a 275/40 tire fitting up front and not having any rubbing going on. Is there any back space setting that would fit this up front.

The seller says they came off his 68 camaro and everything should fit. Since he is local I can go by and see for myself but Im kinda iffy on the tire sizes. Im only enteraining the idea since he is selling them for a good deal.

What does everyone think about this?

I would think the fronts would be to big. But if its a good deal you just need 2 more tires.

I think the guy wants to sell his wheels...badly

There's no way 275 will fit on front wheels without modifications. 245 is pushing it for the front...and even then, would probably rub. Hell, most of us would have some rubbing with 275 on the rear! But hey, if you're getting a good deal...you can always change the tires. 17x8 is fine for front...as a wheel size...and would work fine for the rear, too.

Oh, and the BS for 17x8 would probably ideally be 4.75".

Re: Tire and backspace question

Thanks for the info guys. I figure I would run probally a 235 up front. The main thing is I just want to make sure he didnt get some crazy backspace that would screw up me running 235s. Im going to check them out and see how they fit.

Re: Tire and backspace question

275/40/17 on all four corners

http://www.geocities.com/casanoc/

never say never...

Now, there was a need to use steering stops, and carl also used tubular control arms.

and here with some frame modifications

Also, as said before, I think 8" rims is too narrow for that size tire.

Luckily, the OP figures 235 max for up front. Who the hell would want 275's up front?

Re: Tire and backspace question

Oh well the rims sold. This is now a moved point but still good info for the next time. Just have to sit and wait for another deal to come around.

Im looking for the TTIIs 17x8 with 235/40 up front and 255/40 in the rear. I need to measure to see if I can fit the 9.5" rim and 275/40 in the rear, if it fits I will change my specs. I got 1200 max I can spend on this but I think I can find a set, maybe slightly used in this price range. My eyes are back to searching for now.
