    Tire Size Reccomendation 21x9.5

    Guest-only advertisement. Register or Log In now!
    Need tire Reccomendation as I go to an OEM style setup. Currently running 295/25R21 on a 10.5" wide wheel.

    The car came with OEM 20" wheels with 265/35R20.

    I am now going to a RS6 performance 21x9.5 wheel and my car is lowered on KW HAS.

    I am debating between 285/30R21 vs 275/30R21. I do not want a stretched look. My understanding is that the RS7 performance wheel is 9.5" wide? Is the OEM size 285/30R21 for RS7 performancr wheel??

    I know the standard 9" wheel is running 275/30R21.

    Any inpout would be great

    RS7 Performance wheel is not 9.5", it's 9" and same +35 offset as the RS7 Blade. 275/30-21 is the standard size. Some RS6 wheels are 9.5"

    Do you think 275/30R21 will look stretched on a 9.5" RS6 style wheel ??

    Look at the bottom at this chart for the RS7 performance... It shows there is a 9.5" wide wheel but uses 285/30R 21

    Would be interesting to find the part number. The US Performance RS7 wheels are 21x9" RS6 9.5" wheels are usually in the 2x ET.


    Tires will vary from different makes and models. Pretty sure my oems came with the continentals. They weren't stretched but not much lip protection, 285 on a 9" could be kind of meaty depending on the tire. I run a 285 PSS on a 9.5" and it is meaty with lip protection. Some vendors won't like 285/30-21 since it is technically taller than oem.

    I understand my RS6 performance has 21 x 9.5 rims with 285/30R21 tires. Here's a picture:

    Thanks so much for the pics. I like the meatier tire but since lowered I might go with 275 to ensure no rubbing. Very hard decision!

    Are you rubbing at all now with your current 295 set up?

    Lowered on KW HAS, think it just came down from the lift. It's a little lower than the image. I don't have many photos of my actual car, a lot more photos of car parts. LOL

    I rub slightly on full compression, a higher offset wheel with the same tires or a less meaty tire like the original owners set up would not rub. Comparison to stock. https://www.willtheyfit.com/index.ph...9-5&offset2=22

    Your old Morr forged wheel was almost 5mm more aggressive than these HREs. https://www.willtheyfit.com/index.ph...9-5&offset2=22
