Would like to know what is the widest size tire I could use on the front & rear of a 69 coupe with 15X7 vette rally wheels and a new standard original hight suspension without any rubbing or tire clearance issue's? thanks Steve:yes:

the most common combination is 215/65/15 or 225/60/15 front and 255/60/15 rear

I have 15x7 Rally's all the way around. The Corvette Rally's were actually 15x8. As far as the tire size: I have P235/60/R15 all the way around on my 1969 Camaro. On the rear if the leaf springs are good you can get away with P255/60R15. I have seen some guys run P275/60R15 and in extreme cases back in the day a friend of mine was running N50-15 on the rear of his 1968 Firebird. This is equivalent to P315/50/15. That's really pushing it.

Bottom Line: I like having the same size all the way around on this car. But if you like a different look P235/60/R15 will work up front. The P215/65/R15 & P 225/60R15 as TSTONE said is common. The reason is that P215/65/R15 was original equipment on Z28's from 1982-1987. The 5.0L (305 equipped) IROC-Z also used this size from 1985-1990 and so did some RS Camaro's from 1989-1991. The P215's also were on Buick Grand National's, Pontiac Grand Prix's, Olds Cutlass and some other cars as well. The P225/60/R15 was original equipment on 5.0L V8 Ford Mustangs from roughly 1985-1991. These 2 sizes (P215/65/R15 & P 225/60/R15) will be made for years to come. As far as the rear the P255/60/R15 fits with no issues and in some cases the P275/60R15 will as well.

Good Luck!!

Big Steve,

I'm running 15x7 Torque Thrust II's all the way around on my 68'. The 255's are a nice size for the rear and I was told by the folks at Discount Tire where I live that I would not want to go any wider with that size wheel. The car has no air shocks but gives the illusion since the front was dropped by about 1.5 inches with the installation of the Hotchkiss cut down front coil springs. Check out the picture of my 68' in this thread: http://www.camaros.net/forums/showthread.php?t=108064

What size tires are you running on the front?

I am running BFG 215-60-R15. I'm not a white letter tire guy on 67-68 Camaros so when I had the 255's put on the back, I had all the white letters turned in.

So if I use 15 x7 vette rally wheels with P235/60/R15 all around I will not have any clearance problems? thanks Steve

Steve you should not have any problems. I had 235/60/R15's on the back before I switched to the 255's. You might want to reconsider the 235's on the rear and opt for 255's. I could email you more pictures of the rear of mine if you like.

Sounds great if you could, would the 255's work on 15x7 wheels or would I need to go wider? thanks Steve

Here are more pictures of my 68' with 255/60/R15's on the rear. The backspacing on my 15x7 Torque Thrust II's are 3.75.

The front and rear wheels are 15x7 American Racing Torque Thrust II's with 3.75 backspacing. ' I'm guessing at the backspacing because that is the only backspacing available on 15x7's. The only thing that differs is the bolt pattern spacing. The front tires are BFG 215/60/R15's and the rears are BFG255/60/R15's. I had the white letters turned to the inside since I don't remember white letter tires on new 68 Camaros. I have never really cared for white letter tires on cars since the get dirty quickly and to me make the tire look smaller by jumping out from the rubber. However, to each his own. Here is a picture of the car with the old BFG 235/60/R15's on the rear with the white letters facing out. This is also before I added the Hotchkiss cut down front coil springs.

Here's a 69 I restored a couple years ago...It had 245's on rear & 225's on front....I think the 235's on the front would have been better.....But I had no issues with this setup....Dan

The only 15x7 Corvette rally wheel was a one-year-only wheel for '68, coded "AG"; they had -.28" offset, and the Camaro "YH" 15x7 rally wheel has +.3" offset. The Corvette 15x7 rally wheel will put the outside edge of your tires 0.6" closer to the fenders than the Camaro rallys - probably not the right direction. :noway:

Fwiw, 3.75" b/s is stock on my '67 car.

This is why you have to increase the b/s'ing to fit wider rims or you get out into the wheel well moulding!!

And on the back, a 17" rim allow's the lower shock mount to fit right up inside the rim so that you can run some BIG, WIDE tires on the rear..

Otherwise, it's basically back to the 3.75 to 4.+ b/s with smaller dia. rims like stock..

I just went thru the whole what size wheel tire combo and here is my opinion.
I built a jig to check what wheel/tire combo would work the best because I wanted to use the same combo all the way around for rotating purposes so I went with 15x8 ralleys with 235/60/15 tires and 4 1/2" backspacing. They looked great and fit great but when cornering hard (standard height front end) they rubbed on the front fenders. There went my rotating theory.
I've since left the rears with 15x8's but 255's would look better. 235's on 15x8's have a little of that low-rider look, where the wheels are way to wide for the tire.
The fronts have just been replaced with 15x7's and standard 4 1/4" backspacing with the 235's and everything seems to work great.
I'm getting ready to change my rear springs out with a set of mono replacements from JC Whitney, so I'll see what I do with the rear tires.

Fwiw, a tire is fine IF it's bulge stick's out past the rim lips!!

My 225 fronts are like a 1/4" or so on 8" rims!!

I want the tire bulge to protect my rim's lip if I curb her is all...

Further to this discussion, will 235/60/15 work up front on TT2's 15X7 (3 3/4 BS) Sounds like they will but need to be sure - stock ride height on 68 ??

Thanks.

If you are interested, I have a new set of Goodyear Eagle GT IIs for sale. The size is 235 60 15. I am going back to a redline tire. Please let me know.

American Racing wheels Torque thruster II wheels 15x7 but with what the bolt patten 4.50? I'm going to use P225/60R15 BFGoorich tires on all 4 wheels. Its a 1969 coupe has standard springs up front and 5 leaf on the rear.
