Tire Advice.....help please

[C ///M]

C//M, with the space I have in the back I really doubt a 235 will ever have a chance. You do make a good point on the (more tire more protection) though. The streets here are horrible.

I run 235/40R17's on 8.5x17's all around on my e30. My wheels were also et30. I'm even using 10mm spacers up front and 8mm spacers in the rear and I have no rubbing at all. I have rolled inner fenders, race springs, and the higher rear arches. The thing is, even though I have the higher rear arches, I'm running the 8mm spacer in the rear and still have a good deal of space. I'll be running 265/35R17s on 9.5x17 (et30 or et25) out back in the next few months. WIth your later rear arches, with et30 and an 8.5x17, I really think you'd be fine with 235/40s. As long as you roll your inner fender lips, that gives a ton of extra space. What springs are you on?

I have GCs....I'm not sure what the rating is though. What spring set-up are you running?

[C ///M]

-Bavarian Autosport Front StressBar
-IE Stage III Race Springs
-Bilstein Sport Shocks and Struts
-IE Swaybars 25mm Hollow Front 22mm Hollow Rear
-M3 Aluminum Control Arms
-M3 Urethane Offset Control Arm Bushings
-E46 M3 Cabrio Rear Shock Mounts
-TC Kline Racing Nascar Pro Stud kit

I have a guy who wants my Bilstein Sports so I may be replacing those with Koni SAs in the very near future.

Nice set up, I have Koni Adjustables.....I am going to start looking into the different tires, sizes and prices tomorrow. Thanks for your help :up:
