SOOOO yes stretching does shrink tire (but not much). Glad to put this to rest.

Thank you 4 years of math...


Are the tires brand new and how did you measure the circumference?

Recommendations for making these look low pro and sick.... yet functional?
(they arrive tomorrow)

Thanks!

Or 225/35/19 and 255/30/19 for more stretch. http://www.e90post.com/forums/showthread.php?t=689691

9et24 with a 235 is about the same as 8.5et17 with a 225. 10et24 with a 265 is about the same as 9.5et17 with a 255. I think that should be just the right amount of stretch. I think it would even be possible to go up to 245 and 275 with alot of work. Also 245 and 275 wont work on an xi.

So I mounted the fronts only (rears were stuck on there good and after 15 mins of hammering and prying, I gave up because it was just a test fit anyways) and there's more wheel gap then expected up front, but pretty tight when you turn the wheel to the liner.

I'm running the 235 / 265's and wanted to drop it like its hot, but worried about being able to turn the front wheels and the rear fender wear on the tires.

Can I get away with running coilovers?

Yes you can get away with those tyres, but rear at least needs fender roll. Member Chuck has those sizes. http://www.e90post.com/forums/showthread.php?t=883948
