I just purchased a set of 15x8 rallys for my '65 vette. I was told by the manufacturer they would fit. The front fits, but the rear ones are hitting on the inside. Has anyone else had this problem? What is the remedy? Should I try spacers?
First you need to tell us where they are hitting. Spring, frame, body, trailing arm, brake cable bracket, brake caliper, etc.
It is very important that you are able to thread the lug nuts on at least the depth equal to the stud diameter, i.e., if 7/16th dia, then thread on at least 7/16th inch deep. Spacers reduce the ability to do this when using tapered seat lug nuts and that is all you can use with steel wheels.
The factory 8 inch rally should have 3-9/16 spacing from the edge of the bead to the backside of the mounting face.
I have to use spacers with that size wheel, but I also replaced all the studs so I could get the lugs on far enough to do the job. If you don't replace the studs, you can't get the lugs threaded on far enough for safety.
My tires are 255x60x15s. Without the spacers, the rear tire fixed itself solidly everywhere and wouldn't move. The fronts would hit anytime the wheel was turned more than a few degrees left or right. Spacers on both front and rear fixed the problem.
Well, let's think abut this a minute. The original tire on a '66 was a
7.75-15. These were around an 80 percent aspect ratio. The section width was roughly 7.75 inches. They fit in a wheelwell designed around a 6.70-15 tire. Snuggly.
The 255-60x15 is tread width 8.00 inches, section width 10.25 inches, and
27.1 diameter, on the average. Not affiliated with JLA Enterprises - mirroring on sites other than alt.autos.corvette prohibited.
Do you see a problem? Understand why so many Corvettes in the '60s and '70s had flared fenders? Where did you come up with the idea you could fit a
255/60-15 in there? Not affiliated with JLA Enterprises - mirroring on sites other than alt.autos.corvette prohibited.
The equivalents of a 7.75-15 are F60-15, F70-15, F78-15, 225/60-15,
205/17-15, and 195/80-15.

It was designed around a 6.70-15 tire. One modification to the Grand Sports was to widen the wheel well to allow the
8.55 in a race tire. Even that was not enough as they found in the first few outings and they flared the fenders in almost no time.

- The rear quarters are wider than '77 and older.
- The front half of the front fender lip is shaved off at the factory for those cars getting the 255/60-15 optional tires.
- the emergency brake cable bracket on the trailing arm was moved.
The 245/60-15 is a full fit in most '68-'77 and the 235/60-15 is a much better fit.
And the '68-82 have full radius fender openings. "Not affiliated with JLA Enterprises - mirroring on sites other than alt.autos.corvette prohibited"
I know of a guy in St. Louis who ran G60-15 (equiv of 245/60-15) on 8 inch Rally wheels on a '66 coupe. Two things were in his favor: He shaved the inner lip and he got lucky. He was also a fairly hardcore autocrosser who pushed the limits so he could go faster. "Not affiliated with JLA Enterprises - mirroring on sites other than alt.autos.corvette prohibited"
Do you even have one concept of what a USENET group is and how it works?
Alt.autos.corvette is not a website nor managed/governed by anyone. It is a public group that only exists because the 10's of thousands or millions of NNTP servers across the globe have decided to carry the group and then make it available to their subscribers via newsreader or web access (wait...would that mean they are making money off of you?) Some keep your posts on their servers forever, some remove them after a week. Google keeps them forever.
That is it. If you do not want your post to appear on servers/sites that carry the alt.autos.corvette USENET group, then do not post anything and quit your crying.
Take a Zoloft or something, it might make you feel better
It appears that Richard is more a "USENET" expert than a Corvette aficionado. Funny, I don't remember seeing Richard in here before the JLA ruckus either. Hmmm, this gives rise to another conspiracy theory!
