Well, I had a nice long reply all typed up...then the power went out.
I run a staggered setup on both of my MN12's. On the 90 XR7, I run 245/45-17's up front on 17x8" wheels with 275/50-17's on the rear on 17x9" wheels. On the 94 LX, I run 245/60-15's up front with 255/60-15's on the rear with 15x7" wheels all around. A taller and wider rear tire really aids these cars in acheiving the right stance, IMHO.
The widest tire that I would recommend for street use on a 7" wide wheel would be a 255 (10" wide). A 255/55-16 would be 27" tall, and a 255/60-16 would be 28" tall. That being said, I don't know if either of those sizes are commonly available.
Awesome! You got pics of the LX? Love to see it!!.....
I'm running with the stock rims, a 16x7 with no offset doesnt leave me much in the option dept, I know, so the 255 was as far as I actually thought I could go.... Naturally, I'm looking to shoehorn in the most treadwidth I can get in the rear without wheelwell rub. I"m firm on a 60 series to keep that sidewall height, and keep it consistent with the 225-60's in the front. Thanks for all the info, Bro!!
PS, love the look of those M/T slicks on the Cougar.....lol!!! Great car, Bro.....
PPS, again, I say, the 93 Cougar is goin on a hook real soon, I've no desire to sell a car with a s#!t Tranny, and no time to play with another toy, my band and this Tbird are more than enuff to keep me busy!!! lol
Sooo, if anybody needs anything, speak up.... I'm happy to part it out to anyone stuck for parts. You pay the shipping, natch......
All you guys have been real great with the info and I love this site, so anything I can do for the 'brotherhood'.... lol!!
