Front tires rubbing

I have a 67 Camaro, I have up front.. Progressive Rims (Pro 64) with BF Goodrich Radial TA P185/70SR14....And on the back P245/60SR14.
I remember That I had to put smaller tires on the front because od the rub...now it's time for new tires up front, because they are worn on the outside edges.
I wanted to put a little wider tire up front so that it would look better. So, I tried my P245/60SR14 tires up front.
The drivers side looked like it would not rub...but the passenger side rubbed without driving, just turning the wheel back and forth...It rubs in the back, as the tire goes into the wheelwell.
Why would I rub only on one side????
and any suggestions on tire sizes???
I would post pics but did not find that option in my post.
Thanks
Barry

Re: Front tires rubbing

Barry,

In my experience with first gen's you can usually get more tire on the front of a 1969 vs a 1967 or 1968 and more tire in the back of a 1967 & 1968 vs a 1969. That being said I ran stock 14x6 Rally's w/ P245/60/R14 on the front of my first 1969 Camaro and they did not rub. If I'm not mistaken the original equipment size on your 1967 Camaro may have been E78x14 or probably F78x14. In a radial size that comes out to be P195/75R14 which was OE by GM for many years once radial tires came into play in the 1970's. Some may have had P205/75/R14's. But the 195's were much more common. FWIW in 1969 Chevy also put larger tires on teh front of a Z28 and that trend continued in 1970 albeit the 1970 Z28 is a completely different car.

Remember these first gen cars were designed & built over 40 years ago. the tolerances were much looser. On both my 1969's there was a bit more lean on passenger side by like a 1/2 inch - 3/4 inch. That was the case 20 years ago and it is today.

The + series equivalent of an F78x14 is P225/60/R14....Here's a helpful link http://www.turbinecar.com/tires.htm On your 1967 you can try P235's but I would go w/ P225/60/R14's. If you wanted to go w/ P215/65/R15 that was OE on many GM cars during the 1980's & early 1990's including Camaro's and that will also clear just fine.

Stick w/ P225/60/R14's in the front. I hope this info helps you out. Good Luck & Happy Motoring!

Re: Front tires rubbing

Sounds like it may be a backspacing issue. Perhaps too much backspace hence the tire is fitting too deep into the well. Have you tried a 1/8 or 1/4 inch spacer to shim the wheel out and see if that resolves the issue? Seen some run 245 successfully on the front but others have reported issues with rubbing and rim making contact with outer tie rod on lock to lock turns. As to why only one side rubs...It could be related to front clip not being perfectly centered. Measure the horizontal gap between end of outer tire and beginning of fender lip and see if it's exactly the same on both sides.
