On a recently purchased 2004 RS6 - I have 255/40 ZR 18 Y XL tires which will need replacing next year.
I have a chance to purchase a set of brand new rims and tires from a 2015 S4. The wheels are 19" OEM and have 255/35 ZR 19 Continental Contisport Contact 3's on them.
Would these wheels and tires be ok to run on my RS6? Should I also be making sure the tires are Y XL?
Thank you
