Hello. I have a 2006 550i BMW non sport.
Currently have Style 172 BMW Wheels staggered with Front: 245/40R19 , Rear: 275/35R19. Cinturato P7 Run Flat

I'm interested in replacing my current wheels with AVANT GARDE® - M540 - https://www.carid.com/avant-garde-wh...-44298110.html

Will the current tires im running still work, or do I need to use the 275/30R19 they recommend with these rims? I live in a big city with a lot of bad roads & would like to keep the 275/35R19 with extra meat if possible.
One of the posts I read when trying to find answers said something about the offset has to match or something or the old tires won't fit?
~Thank you.

With those wheels, it looks like you have to specify the offsets when you order. The Style 172's have an offset of 18 in front and 32 in the rear. As long as you stay with those, you know they'll work. Yes, using your current tires should not be a problem.

 

Thank you.
