Which Ralley wheels for my 68??

I decided to go with the ralleys on my 68 vert. My question is that I have a set of 15x8s and a set of 15x7s. I already ordered the tires, 225/60/15 for the front and 245/60/15 for the rear. Should I go with the 8s or 7s? I don't want to use different sizes on the front and rear because I don't want to break up the sets. Thanks

Re: Which Ralley wheels for my 68??

I run 15X8's on the rear with 255/60/15's or 275/60/15 drag radial's and I have not had any "rub". I have also had 295/50's on the same wheels with no rubbing. See my sig for pic's

Re: Which Ralley wheels for my 68??

the 15" x 8" are too wide for the front....IMHO, so I would go with the 7's...But if I were you I would break up the set.....because that is the exact set up I have on mine and it has the perfect stance I was looking for...225's on 7's and the 245's on 8's.....again, only my biased opinion!

Thumbs up Re: Which Ralley wheels for my 68??

I agree...15 X 8 rear, 15 X 7 front.
It will look best that way. 15 X 8 on the front is gonna rub pretty bad no matter what tire you put on it. You could do 15 X 7 all the way around, but where is the "meat" on the back end of that car?

Re: Which Ralley wheels for my 68??

I put 275/60/15 on a 7" ralley wheels on my 67 coupe they fit no rubbing and nice fat meat on the rear. the side walls did have a little roll but they fit and work well for clearance. You can put up to a 10" wide tire on a 7" wheel 8" is the preference but 7" will work. 275's will rub on 8" wheel. I had 275/60/15 Hoosier Quik Times on the 7" wheels once they were used up went to 245/60/15 not near wide enough after having the 275's on there.

Wink Re: Which Ralley wheels for my 68??

Carguy you've got a lot of choices but here's another thing to consider. I ran 245/60R15 on 15 x 8 ralleys. I replaced them today after much thought and measuring with 235/75R15 on 15 x 7 and could not be happier. The car looks much more serious now as the 235/75 fills the wheel well perfectly. Leaves only about 1.5 inches clearance to the front and rear lip of the wheel. I know almost everyone has a love affair with the lower profile tires, and there are many benefits to them, but IMO they don't look good on a 67-8 body. To me appearance was the most important item on my list and I don't want a lot of empty wheel well showing on my car. On my SS I had 4.5 inches of empty wheel well between the top of the tire and the lip of the rear wheel well opening and to make matters worse the 15 x 8 wheel puts the tire flush with the wheel opening of the car. It ocassionally did hit when going over very large bumps, potholes, ect. The 15 x 7 rims besides being 1 inch narrower have 1/2 inch more backspacing. This means you move the tire 1.5 inches in from the lip of the well, not just 1 inch. This fact alone is why I would not run the 8 inch rims, even if you still run the 245/60 tires.

The combination of the 245/60 tires not fitting inside the well on 8 inch rims and being so short just took away from the cars appearance to me. The 235/75 is only slightly narrower and fills the well. Yes the 29.1 inch high tire does cut down on my gear ratio compared to the 26.6 245/60, but I'm changing that anyway next Winter. I ran the 235/75 on my 68 Z for the same reasons mentioned and loved it. This car didn't hook with the 245/60 unless you were rolling 30 mph anyway and then it still got pretty sideways at times. With the 235/75 it does get a little more sideways from a 30 mph roll, but that's to be expected.

As far as front tires you have a lot of choices, but you can't run the 235/75 on front they are too large.

Here's a good link for playing with tire size, just remember your 15 x 7 ralley wheel has .5 inch more back space than a 15 x 8 and will put the same tire 1.5 inches further into you well.

I think DJD posted it a while back, it's excellent for comparisons.

Re: Which Ralley wheels for my 68??

sy1 - Did you mention the wheel / tire you are running on the front? And why didn't you go with something like a 255/70 on the rear to pick up some traction? And, do you have any pics? Sorry for the many questions but you have got my curiosity up with the good information you provided. Thanks!

Re: Which Ralley wheels for my 68??

This is the my car with 235/60-15 up front on 15x7 and 275/60-15 on back with 15x8 ralleys.
The 275's on 15x8's seem a little too much. I think they are sticking out a little to much from the fender. I also want to fill the wheel well with a taller tire or less arched springs. So the dilemma is a 15x7 inch rim on the back a nicer look? should I go with a 70 series tire 255's... It can boggle your mind if you think about it too much.

The 275's on the back are unreal (drag radials, BF Goodrich) can you say no spin!! excellent for driving to the track and racing with no hassle.

Re: Which Ralley wheels for my 68??

For what it's worth, I like 255/60's on the rear, 215/65's on the front

Re: Which Ralley wheels for my 68??

Rogue68 the 255/70 would've been a better choice for me as they are 1/4" taller and aslo wider than the 235/75 I went with. I think I so hated the way the 245/60 tire looked on the car with the 15 x 8 rim that I had it in my mind to I had to go narrower, so the 235. However the 255/70 on the 15 x 7 with the tire set in 1 1/2" with the new rim would have probably been a better choice. I could have used the traction as well. I'll run these until I park the car and probably try the 255/70 you suggested. I also removed the trim rings as they don't stay on the rear of the car if I really drive it hard. I got a good deal on the BF Goodrich Touring radial 235, about half the price of the larger tire you suggested. With two kids in college it's something I have to consider if I want to do all the other things I need to this car.

I didn't mention the front because they will be the next thing I change. 15 x7 with 215/65R15 on this car the way it sits I don't like them. The car originall came with 14 inch ralley, which are long gone, had Convo Pros on it when I bought it, those are gone now, previous owner didn't spend any time selecting the right size wheel and there were a lot of issues with 15 X 10 on the rear and 15 x 4 on the front, both with terrible offsets. He threw in a set of 15 x 7 front ralley and 15 x 8 rears, I ran them for a month before I decided I needed a change, started with the rear.

I'll probably run a 6 inch front ralley, maybe try a repop 5 inch if I can find a SFI approved. I'm considering 195/80R15 front or a 215/70R15. Narrow and tall. My 68 SS sits higher than most, especially in the front. My 68 Z and RS with the 302 front springs both set much higher in the front than most I see now.

Dan's 68 RS/SS looks great with his 60 series tires, but his car sits much lower than mine. He's done a great job selecting his wheels and tires and I like the stance and look of his car in the pic he posted. My car just sits significantly higher and I need a taller tire to fill the well. I don't want to lower the car, because the way I remember these when new was they did sit a little higher than most you see today.

My car sits more like Johnnys in the rear, but a little higher in the front than his. It too is a nice looking car with a great stance, but I had about the same space in my rear wheel well to fill as he does. A lot of guys don't mind that, I just want to fill it. It's all subjective. So start by looking at the stance of your car and decide which way to go. Every car is a little different.

I don't have a photo hosting site right now, I can email a pic if you'd like. I also have to add following my advice you may hate it afterwards, I love that it's different than most. I find I usually am in the minority in what most look for in a first gen. Just like things a little different than the norm.

Re: Which Ralley wheels for my 68??

I will tell you that the black car sure would look cool with my old L-60/14's on my old Fenton 14" x 9" Slotted Mag's on the rear!

They measure a modern 298/53-14 and are right at 26.5" tall. 11.5" section width if I remember right?

Talk about BIG donuts!!
