Hi,
My name is Russ and I have a 69 mach 1 428 auto-black jade.
I'm looking to change my tires and wheels. Anyone have any info on max. tire size (no fender rolling) and backspace. I'm thinking 15" wheels. Any pics would be greatly appreciated. thanks

Welcome Russ.

I'll let those with 69/70 models jump in with their advice on maximum tires size.

There should be a couple of threads that deal with that as well if you care to do a search.

Feel free to share some of your history with Mach 1's and this Mach 1 in specific if you would like.

I'm with Steven on this one as I never had a 69-70. So not really sure. Jump in anytime. JTS 71 Mach1

Welcome from Ohio
Stock suspension can't go to big in the front - Ford rolled the Boss fenders to fit F-60-15's
Soory I don't have size info for you - it will also depend on back spacing
You might find some specific size info on the 69 - 70 Boss forums
