Does anyone have a chart for wheel and tire fitment on a 66 coupe ? I am looking for upgrade my from tires/wheel. I have disc brake and I would like to replace them with the biggest tire to match my 235/60/15 and 15x8 back ones. I have already rolled up the inner fender lip.
Also can I run 235/60/15 in front as well? I really want the same all around but not sure if I can.

Also I can’t find 4.25 backspacing. The one I am looking at has 3.85 is that ok
Is this the same car that many here thought the front end was too low on before?

Your car sits way too low in front to run even a recommended standard wheel and tire size, and just never mind a 235/60 on a 15x7 with only 3 7/8" back spacing. Here's the chart showing what fits good with a stock factory height suspension, which again, yours is nowhere near.

For 65-66 17x8 4.75” backspace is ideal. :)

3.85 backspacing will not be enough for that tire size. My friend just went through this and had to buy smaller tires. Check the charts, but you also have to consider your ride height.

I will tell you from personal experience. A 215/60/15 tire on a 15x7 is very tight on my 66. I still get a little rubbing. I have a Street or Track suspension that has a better camber curve, Arning drop and run 1.125° static negative camber for tire clearance. I also have 600# front springs

With 3.75” backspacing, right? My 15x7 with 4.25” backspacing has no issues in that size.

Please allow me to reiterate from before. The OP's front suspension is way lower than stock, no Arning drop (too bad according to most of us here but apparently how low it is matters more than exemplary handling), and that means all bets are off regarding fitments. He is screwed at his current front ride height trying to fit even normal recommended wheel and tire sizes, let alone what he wants. Some rethinking of things is in order. OP, please stand back and take a good look at your car. The front is too low, the rear higher than most would want. Fine. We/you can deal with that, but it means you taking some of the advice you've already received in the threads you've posted, at least one previously. Just as an aside, if that's purple/violet window tint it kind of looks like.., Oh well, never mind, it's your car and it's yellow like this smile. :)
