I am looking to put 18" wheels and snow tires on my car ('08 S6). The oem wheels are 19x9 ET52 and tires 265/35/19. The set I am looking to run in the winter is 18x8 ET45 and tires 245/45/18.

Is this offset too large or small for the car? Will this set up mess up my spedometer?

Thanks!

 

I have the OEM 18" rims that I want to sell....They have 255/40/18 tires on them...Are you interested in selling your 19's....I'm in CA so I don't have to worry about the weather...
