I've purchased 2 15x8 ralleys for the rear and 2 15x7 for the front of my 69. I'm not sure of the backspacing just yet, but assuming the backspacing will work...I would like a little smaller tire up front, but pretty good coverage out back...what are my best options?

What about ANY of the combos? (if they'll fit 15x8 or 15x7)

Rear (15x8) = 255/70SR15
Front (15X7) = 255/60SR15

Rear (15x8) 275/50SR15
Front (15X7)265/50SR15

Rear (15x8) 235/60SR15
Front (15X7)225/60SR15

Rear (15x8) 275/60SR15
Front (15X7)255/60SR15

Rear (15x8)275/60SR15
Front (15X7)265/50SR15

Rear (15x8) 255/70SR15
Front (15x7) 235/60SR15

Rear (15x8) 255/70SR15
Front (15x7) 235/70SR15

Rear (15x8) 275/60SR15
Front (15x7)235/60SR15 (Maybe my favorite combo if it will fit...I wouldn't mind a smaller sidewall/overall height up front..

Thanks,

The last option you have listed is what I have, but mine are Cragar SS's with 4" backspacing. They fit and look great.
See pics below.

I am running the last combo on my 66 on 15x7& 15x8 draglites. Fits nice.
