Lightbulb 437m 235/40 - 265/35 runflats? where to buy?

Hey guys. I'm pretty new to this forum and to modding in general. I recently just purchased a 437m wheelset oem and after the researching I was concluded to try 235/40/19+ 265/35/19. I'm actually trying to find all 4 with run flats in tirerack but I'm having trouble finding them. Wondering if anyone can help me out or can recommend me. Thanks!

I don't mind changing the sizes as long as theres no rub and within 1% for xdrive. Thanks!

Do you really want run flats? They pretty much suck for ride quality.

Well, the thing is I bought warranty for runflats. So that's the only reason why I have to stay with them. :T

Isn't the warranty for the original wheels and original runflat tures that came on the car? Or optional oem bmw wheels/tires that may have been included as part of the contract.

I dont believe M wheels like 437M, 513M. 666M, 763M and associated tires would be covered.

So, I've been eyeing on the Pirelli P7 All Seasons Runflats. Planning to use those on 245/40-19 and 275/35-19, crossing my fingers hoping it will be fine on stock suspension.

245/40/19(26.7")+29 will probably rub the fenderwell liner during full lock turns. Let's us know if it doesn't.

19x8.5 +35... 235/40r19 is the size I want but not alot of tire available on this size. I heard MPSS, MP4S, MPS4 but I'm not spending $300 on tires... shopping for UHP around $150-220.

I type the size on www.tirerack.com very few selection comes up.

But this is the ideal size than the recommended or what everyone is using 235/35r19 and 265/30r19 which make it smaller that stock
