Please let me know what exact tire and wheels you are running on your barracuda's 67-69 if you have disc brake conversions. I see so much conflicting information and I would like to get tires on my rims. I have 15x7 with 4-1/4 BS on the rims. It looks like my safest bet would be 215/60/15 but unable to find RWL tires other than Radial TA which are pretty high priced. I like cooper cobras and have used them number of times but the closest tire that I con find is 215/65/15 - which might work but I would be lot happier if I knew someone has tried with good luck.

I am getting some 15x6 torque thrust style rims also but it appears with 3-1/4 backspacing the same corner of the tire rubbing would still be factor.

Any experience you can share will be appreciated.

Thanks,

BRyan
 
I have an SSBC disc brake conversion on my 69 cuda. It had 14 x 5.5 rally wheels with 215 70 14 on the front when I got it. I bought 15 x 6 cragars 3 3/8 back space, I think. I am running 195 60 15 on the front now. Wish I would have went one size larger.
 
A 215/65/15 will be 26" tall, which could cause issues with the front lower corner of the wheel opening. That's a pretty common issue with the Barracuda's the wheel opening is pretty tight. You'd honestly be better off with a 225/60/15, but it doesn't look like the Cobra's come in that size anymore.

What disk brake conversion do you have? The track width/backspace will make a difference.

It is I think newer calipers. they are the one with pins and one big piston. bought them with bunch of parts and were in good shape. came with tubular A arms so pretty much everything - though they were used

Single piston calipers with pins are definitely a big bolt pattern set up, and work with the 73+ spindles. The pin style were typically B/E body calipers, although some of the FMJ car models had them as well. Those are the larger 2.75” piston calipers too, little extra stopping power compared to the ‘73-75 A body calipers that had 2.6” calipers.

Anyway, for rims and tires that means you have the later 73+ track width. So with a 15x7 and 4.25” of backspace a 225/60/15 is about as wide as you can go. I’m not a Barracuda guy specifically, but I would be cautious with the 215/65/15. The wider track will put those wheels pretty far out, so that lower front corner could be an issue with those being 26” tall.
