So I blew out one of my rear tires. 10,600 miles, needed new skin anyway. shopped around for OEM replacement SpotContact2 - 275/30/19. Dealer had the best deal for me. installed today.
I pick up car, notice it isn't as stable as before. a little wandering on the road, not very BMW sport package like. notice the size on tires didn't sound right. look at paperwork, see they installed 285/35/19. paperwork says also installed 275/30/19. so, couple questions:
1. is this standard BMW replacement now?
2. is there any benefit to these larger tires?
3. rubbing? etc?
any other thoughts? should I go back to dealer and ask what's up?

Don't know whether BMW changed spec, but I doubt changing one tire to a different size is a good choice. If anything, replace both (front or rear) with the new size. Not an expert by any means but a different size tire on either side of the car should affect ride and handling. The 550 Sports Package has a staggered set-up, different size tires in the front and rear.

1. I wouldn't think so. Standard 19" tires would be 245/35/19 and 275/30/19 (or if you went with 285, it should be 285/30/19)
2. It might give a little more rim protection, but your tire series/diameter is off with the fronts.
3. Can't answer without knowing your rim width and offset.
What's your tire size on the fronts? Personally, I would take it back and insist they install the correct tire size for the rears.

Looks like someone screwed up and didn't tell the customer again -- or it couldn't have been an honest mistake

stock car all around. 172's, no spacers. OEM tires on front, 245/35/19. i noticed immediately the sidewall was wider than last set. I will return to dealer and find out what happened. I'm wondering however, if this would make the car wander like that? they also did a ISTA/P update, could have changed active steering ratios again? feels more cadillac like.

so you have 2 different size tires in the rear?
that would definetly cause it to drive weird.

no, same sizes left and right, not same size as oem though, or what was ordered.
