Largest wheel and tire combo for 69 F-body

[jlwdvm]

I have a 69 firebird that I will eventually be ordering new wheels and tires for, something with a vintage Trans Am look. Anyway, what is the largest wheel and tire combo for the front and back with stock subframe and wheel tub (+/- rolled rear fender lip).

Not exactly Vintage looking but here's a 69 we put 19x8 and 20x10s on with stock wheelwels and Air Ride. 8s and 10s are a safe fit in any diameter with a 69 F-Body.

ive got 20x10 w285/30 they fit but its very tight and if you have lower ride height you have to watch dips etc. i am going to end up minitubing mine. you maybe could do a 275/30 but imo they do not look right. my 285s barely look right
