I just bolted on my new rear setup and it looks terrible (IMO) the wheels/tires stick out way too far. (rear is 15x8 vette with 255-60-15 BFG)
I am thinking of going to a 15x7 in the rear. what is the stock backspacing?
I have 215's i the front was thinking of 225 or 235 in the rear. Will the back spacing and 15x7 rim pull a little of the "joe dirt" look out? I'm just worried that the 235's will still have a little of the look to them that I currently have, but will the stock BS and 7" rim might fix that.

Matt, 235/60-15 is what I was running all around on 15x7 ralleys. They will definitely not stick out as far on the rear as the 15x8 255. But I wouldn't go any smaller than 235/60 on the rear as they would look too short in my opinion.

I went up to 15x8 on the rear with 235 to get the tires a little closer to the wheel well lip. If I can find a photo, i'll post it up.

A pic of your car would be great! what BS did you use on the 15x7?

Yep I had that problem with AZ coded Corvette 8" rims,they have 4" back spacing as opposed to the 4.25 back spacing of the standard 7" rim.
It becomes a bigger issue if the car is lowered the tires will rub badly.
I personally couldn't handle the look of the rear wheels sticking out like that or the tire contact with wheel arch so changed rims.

Hi Matt,
Here is my 68 with 255-60-15s on the back and 235-60-15s on the front. The rims are 15x7. You are correct, the 15x8 Rally Rims push the rear tires too far out. I did not like the look with the Rally Rims either and changed to the Torq Thrusts. To change the look of my Camaro, I have a set of 245-60-14s mounted on the original 14x7 Rally Rims.

15X8 4.0 back space Rally with a 232/60/15 BFG In the other shot they are also on the front, I had rub at full right or left turn and a very lite rub strait at the wheel well on big bumps or dips in the road. Lowered in front with hotchkiss springs. To be honest I thought they would have rubbed alot more and everyplace. These were on as an experiment. The rear could have swallowed a 255 with out issue





These are 15x7 with 235/60/15 on 15x7 with 3.78 back space. Front is coil overs rear stock but empty trunk and lots of other parts missing as you can see. Hope this helps a little. It needs a 25560/15 in the rear. I would like to go bigger if possible and may order my torque thrusts from http://www.etwheels.com/et/classic5.html# I can get a 15x8 with 4.5 inch back space.

Vette wheels have less backspacing then most others. With about 4.5" those 255's should tuck fine.

FW code Rally Rims
15"x7"
4.25" backspacing
235/60R15 at all four corners

I think it looks best when it sticks out. Mine are tucked in at the moment but i guess we have different opinions. I think it looks best when the tires are fat and sticking out.

Finding the right tires for these first gens can be fun. First of all lose the vette rims. They are way too offset for a Camaro unless you are going with a smaller tire.
The 15 x 7 Rallye is what you want. You also have to decide what tire height you want.
The 255 60 is 27.1 inches tall and over 10 inches wide. That would be a rough fit on a 68 unless you want to jack her up.
The diffeence with a 235 or 245 would be quite a lot.
I had 235 60s all around on 15 x 7 s without problems. I think you could go to a 245 rear on a rallye without any issues on the rear. Remember an inch here or there on the tire height can change your rear end ratio and hurt performance. I would take a long look at this but defintely get those vette rims off.

I did lot's of research on this site and was very happy with this setup:
- Wheels: 15X7 with 4" bs up front, 15X8 with 4.5" bs in the back
- Tires: 215/65/R15 up front, 245/60/R15 in the back

Using a 4.5 backspacing brings them in about 1/2 inch but a 255 might rub on the shock plate. I got them from coker but 4.5 was only available in chrome. I actually really like the full chrome without having to use the trim ring. I have my 14X6 stocker rims and caps if I want to change it back to stock.

Exactly what I ran on the '69 when I had rallys.

Matt,
With 15 X 7 wheels.....what size tires are you going to use? I have a a set of 15 X 7 ralleys (FW) to go on my 67 and want to get as much rear tire as I can without the rub.
