69 Firebird Build

[69TAPoser]

235/40/18 up front with 4.75" BS on an 8" wheel
275/40/18 out back with 3.75" BS on a 9" wheel

I went with 40s vs 35s as I wanted a little more sidewall. I probably could have gone with a bit wider 245 up front, but Frank at Prodigy mentioned that you wouldn't notice the difference and the 235 is a "safer" choice.

Don't go by the rear back spacing for your car unless you have a shorter 9" Ford rear. This will give the rears a real nice DEEP dish with that back spacing.

I was also a little conservative on the rear and I may have been able to go with a 285 on a 9.5" wheel, but I measured with a wheelrite tool and it was going to be VERY close and I didn't want to risk it not working out.



I can't imagine what the tires look like in person for you guys running the 315/18s. The 275/18s looks massive to me!
