how wide are your rims...I'm looking at some 17" x 7" rims because I can get them for a good price...the only problem is that they seem narrow to me...is there a big difference between 7" and 7.5" or 8" when mounted? Thanks for the help...the offset is 40 BTW.

I'm not sure that my 215's with fit once I lower the car. The rims are beautiful though; Borbet type T 16x7.5, with BFGoodrich Comp T/A VR4 215-50VR16's. Looks awesome. The width is excellent for handling. I think the widest you can go with 7" wide rims is 205... which is what I had on my old car. They were okay, but not as good as the 215's.

Cheers,
Mike.

nah...you can run a 215 or even a 225 on a 7" wheel...if i can get a tire i like in a 245, i'm gonna try that on my 7.5" wheels. 3/4" width increase from where i am now (3/8ths per side).

compounds make more of a difference than width. width changes the shape of the contact patch (will not change area), so if you change compounds, you'll notice that before width increase/decrease...

the old BFG's have waaaay more grip than the either of the D60's, and the newer style D60's have more grip than the old style D60. they changed compounds a bit, and changed the tire structure...

I am running a 17"x7.5" 215/45/17 Ronal RT on my 91 coupe Q with stock suspension. The handling has improved a lot when compare with the stock tire wheels. I guess 215 7.5" is the max I can get without rubbing.
