I have 225/45R17 Continentals on my fronts and they are perfectly square. Same tires on my 9j rears were slightly stretched. I think I'm gonna do 215/40 next year for moar low and because with the rear offset I run I still rub with the 225s.

Brand of tire makes all the difference. Some tires like Toyo, Yoko, federal tend to run wide so a 215/40 looks more like a 235. You want either a large 215/40 or small/true 235/40. I once ran 235/40 yoko avs and they looked like balloons compared to my Bridgestone Potenza's of the same size. I suggest doing the research online and looking at pics. Some claim 215/40 on an 8" is stretched but it really isn't especially if you are running a wide brand tire. In fact, 215/40 (slightly undersized) is closer to the original diameter of the stock wheels than 235/40 which is slightly oversized.

I've recently picked up a set of 2piece style 5's. I would like to run them on my e30m3. I was interested in what you guys run for a tire size. I don't like the "strech'd" look so I would like to keep away from that. If some people would like to Post some Pictures with tire size, That would be great so
I could visualize the fitment. Thanks.
