Does anyone happen to know the largest width tire on an uncut solid rear axle can be put on these fact five Cobras?

275 is the recommended width.

Some owners have modified the frame to accept 315's. It's not the axle length, it's the frame that interferes.

It also depends on what size wheel you want to run. A 17 inch wheel will tend to rub in a different spot than a 15 incher. I know Eric427shelby is running 295s, with I think 15 inch wheels.

I can only speak for 15" rims. With the proper backspacing, you can run 295/50's on an uncut axle, but you'll get occasional body rub on a hard dip. For "no rub", 275/50's are the biggest you can go.

I have 285/40-18's on 9.5 inch rims with 6.5" backspace. Rear end is standard Fox (60" face to face on the axles).

Happy motoring

What Wade said.

As a data point for tire fits under the IRS (I realize this is about live axle setup) the T-Bird is 63 3/4" wide right out of the car as I tape measured it. I got mine today (ordered kit yesterday)

Wheels and tires are one of my biggest concerns. Want older HB period style, maybe 17", but it appears to be a callenge to get the right look.

I am running BFG 285x40x17" rims on the solid axle set-up with rear discs..

Only issue was no quad shocks I have coil overs that are at this point handling the hop issue

Hmm....

17x11 here!

I chickened out on the 335's and went for 315's tho.
