Does anyone know the biggest front and rear tire/wheel set up can be run on a '69 bird. I'm planning on keeping the stock ride height on the suspension rebuild. Maybe sometime in the future I'll run an air ride type set up, but right now I'm not going to spend the $. I am leaning towards a torque thrust style rim and thinking I can go 20" in the back and 19" in the front. Any thoughts?

I just put on 18" all the way around with a 40 series tire and they seem to be fine. But I haven't driven it on the road yet just my driveway. Hopefully this weekend I'll put some miles on the 67 bird and let you know if I have any problems.

I've 17s all the way around, but if I were to do it again, I'd probably do a 17/18 combo. Anything more looks silly to me and will cost a ton more in rims and tires.

I got 17's and my fronts rub when i hit a good sized bump.

What size tire, and do you know where it rubs?

225/45/17's they rub the out side lip at the top and i had to take out all my bolts and use botton head allen bolts.

Sorry for all the questions, but you have my curiousity up.
What width rim and backspacing did you use?
Do you know what your static camber settings are?
How long since the suspension was rebuilt(so, like age of balljoints and bushings)?

I have 245s with 1 degree negative camber and all new suspension including delrin (solid) control arm bushings. I have decent clearance to the outside lip even under compression, and it just barely rubs on the frame at full lock. It's only an issue on tight parking manuvers, but replacement tires will probably be 235s anyway.
