dealer install wrong tire size?

[wassy]

(duel posted on e60.net forum) 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?

Are both rear tires the same size? from your post I wonder if you dont have one of each size on there.

both same size. other forums are telling me I'll get this cushy ride, and have them replaced with correct size.

slightly wider with slightly higher profile the sidewalls could flex more, usually if your going wider tire you go smaller profile so I guess it could cushion the ride.
check the lug bolts for correct torque?

Agreed, those tires are too tall.
