Need some advice please.

Hello all. I know this is a common question but I also know most issues are a little different. I have a pretty much stock 69 Camaro and having some tire fitment/rubbing issues. I am running really wheels 15x7 in the front and I believe 15x8 in the rear, I apologize I dont know the offset. The front tires are 235 60-15 and the rear are 255 60-15. I recently rebuilt the entire front end and installed a set of Hotchkis 2" lowering springs which outs the tire up into the wheel well a good 1" plus and the tire now rubs on the fender when backing up or sharp turns. The back have always rubbed on the fender lip when anyone is in the back seat or I hit a good dip in the road. I am in need of new tires and need to know what to go with. I am pondering putting the old springs back in... Any advice is greatly appreciated!

Re: Need some advice please.

I have basically stock front end and from my perspective I think 235's on the front are too wide. I have 225's and the rub ever so slightly on full turns.

I run 225/65/15 on the front and 245/60/15 on the rear. I find the taller front tire on stock suspension gives better stance but maybe my rear leafs on the back are a bit soft and need replacing.

Did you get a front end alignment after all the work? To what specs? pozziracing.com has recommended alignment specs. A lot of tire rubbing can be fixed with negative camber.

I did have it aligned, the amount of rubbing seems more than can be fixed with the current tire but I maybe wrong. I was at a show last night a there were 2 with the same stance but of course the owners were not around to speak with.

If you used the factory alignment specs you don’t have enough negative camber. Do a little reading on the Pozzi site regarding recommended alignment specs.

Your car no longer has bias ply tires and factory ride height. The factory alignment specs are irrelevant....

Don is correct on the alignment. If you have the specs on your alignment settings post them.

I'm going to say you have the wrong off-set wheels.
A 255/60 should be nowhere near rubbing. Guys run 275/60's, which are about 1" wider.
I can't really speak for the 7" wide wheels up front except I'm still thinking wrong off-set.


One other thing, do you also have drop spindles or tubular lower control arms ? Yet another reason the front could be too low

I do not have the alignment specs, local small shop did it for me over a year ago. When I decide what size new tires I will install I will have it aligned again and be there with them. The control arms are stock with stock height spindles. I appreciate all the responses and suggestions!

Why wouldn’t you try negative camber before buying new tires? There should be no issue with a 235 tire.

Hey Don, I may not have mentioned that the tires are in need of replacing. They are 20 plus years old and have wear from a teenager(me long ago) and a wore out front end. The car is my baby, but after marriage and a my son, time was limited but its time now to get it right.

And again the front rubbing/hitting is a big concern but the tears rubbing has always bothered me also. At this point it's a two person car. I have a family and it's time to change that.

Re: Need some advice please.

I recommend you measure and post the backspacing of your wheels. Here are the recommended backspacings for first gen Camaros:

17x7 = 4.25"bs
17x8 = 4.75"bs
17x8.5 = 5" bs
17x9 = 5.25"bs
17x9.5 = 5.5" bs

Don,
Do the Rally wheels have the B/S stamped on them or do you have to actually measure to determine it? I guess, now that I look at your chart, I don't have to do either. I can just go by your chart, haha. Shoulda thought about that before I wrote the post. But I have 15" wheels. Wonder if it would be the same for the different sizes?

Thanks,

Brett......

Backspacing is the same regardless of diameter since it is simply centering the wheel in the wheel well.

Easily measured by placing a straight edge across the wheel rim and measuring to wheel mounting surface.
