Bought wheels - recommendations for tire sizes?

Hey all. I just bought volk 19" ce28ns:
http://www.e90post.com/forums/showthread.php?t=904320

The specs are:
19x8.5 et35 front
19x10.5 et25 rear

I have a '10 335xi on the stock sports package suspension. I do a bit of autocross, and I'm looking for recommendations for tire sizes that get the rolling diameters of the front/rear close (under 1%) without the need to roll fenders.

After searching the forums and using the calculator, it seems like all of the options below will technically work:

235/35/19
265/30/19
(.85% difference)

255/30/19
265/35/19
(.93% difference)

235/35/19
275/30/19
(.08%)

My other requirement is I don't want the tires to be stretched - don't really prefer that look. And I understand a square setup (or close) will help with understeer. So I'm leaning to the 255/30 256/35 option. Does that make sense?

Thoughts?

You'll most likely need to roll the rear fenders. The only way you might be able to get away with it is to use 225/35/19 and 255/30/19. The front would be fine and could even use a spacer. There is a chance the rear will rub even with the stretch.

Hmm, even if I only go to a 265 in the rear? It seems like a lot of guys are running 265 without rolling fenders...but probably not on 10.5" wheels?

Like I said I think theres a chance it will rub even with a 255 going up a size isn't going to help.

10.5 et25 is about the same as 10 et19 or 9.5 et 12. Which is fairly aggressive without a roll.

Do you have an e90 or e92? LCI or Prelci?

Definitely wont fit without a roll. This is the same as 10.5 et17 on a prelci. MonacoBlueE90 has 10.5 et15 on a prelci with a 255/30/19. You'll definetly have to roll your fenders and trim the rear where the rear bumper meets the fender, possibly add some negative camber.

Ok, thanks for the info. Given the need for the fender roll regardless, any opinions on the three tire combos?
