RS6 with 21"

[RS6_joda]

Hello, long time lurker, now a proud owner of RS6.
My car currently stands on stock 22" wheels which I would like to change to 21x10.5 with some fat tires aka 295/35/21, possibly all seasons. I don't trash my car, I mostly do city and autobahn driving. Anyone done anything like that already? Since our shops rarely do anything like that, there's basically 0 data if it will fit or not.
Ah yes, the car also has ceramic brakes which is the main reason I'm writing this as I have no idea if this is feasible or not. It also hits 317 km/h (200 mp/h range) with a bit of effort, so I'm not sure if all season tires are rated for those speeds . Any input with fitment pictures is much appreciated.

OEM 21” wheels fit on CCBs...

Would you be able to clear a wider wheel+tyre setup? This is my fitment idea: 21x10.5 with some fat tires aka 295/35/21. Since I have stock 22" 10.5 wheel with 285 width, there shouldn't be any rubbing?

Ask Jimmy at Nemesis on this board.
He has run a wider set up like what you are looking for.

Good luck.

I bought a set of 21” OEM factory take-offs (the silver 10-spoke wheels exactly as you picture) and we put Michelin PS4S on. Very satisfied with ride, road noise, etc.
Originally we were going to put on a winter set, but while this car will see cold weather driving, and maybe some snow, if there’s significant snow we’ll use the Cayenne.
275x35x21
They’re a bit more “stretched” than we prefer, but not too bad.

Done it on my ‘22 model. Bought 21” Forgeline (from Jimmy at Nemesis - he looked after me very well) in the stock width and offset.
Fitted at dealer before pickup, so original rims and tyres had literally only “delivery mileage”
I ran PS4’s in 305 width (can’t remember profile but will update later) from the start

I’ve got ceramic brakes, DRC and Eventuri inlet manifold

I’m now on second set having replaced them at about 55,000kms (just done about 65,000kms in 17 months) and my verdict:

Tyres are brilliant
No pothole problems for me, whilst those all around struggle with torn tyres and bent rims on our crappy Aussie roads
Good ride
No brake clearance problems at all
Lighter weight of the Forgelines means it feels even better (by small increment, but noticeable from the car I test drove - as I never drove mine on standard rims)
Have had a small amount of touching/rubbing on some plastics on inside fronts - dealer trimmed with Stanley knife (inconsequential trim piece) and no more issues
I would think that if you pushed it out say 5mm with offset adjust you would possibly remove the inside “touching plastic” issue and also fill out the guards (oops - fenders in USA) a bit more. I was after “flying under the radar” so no problem for me. Of course I could just revert to 295 width tyres (not the standard 285 wide as noted for 21’s but 22’s have 295’s)
I wasn’t originally considering 21’s, but so glad that I ended up with them as I like them. Maybe if I was feeling a bit more “bling” then I’d go for one of those standout gold 22’s or whatever bling wheels with the offset pushed out as far as it could go … but that’s just not me. However, if I was going to, I’d be back to Jimmy as he knows what fits and what doesn’t. Check the pics of his RS6 - nice

Ordinary pics of mine below but tells the story

Just found his thread. Thanks for pointing him out.
I like the looks of 22" but shitty roads and DRC ride quality in RS2 mode just forces me to get 21" with some more meat.

[Astonished]

Good plan
However, don’t expect the 21’s to be a cure for DRC on RS2 mode as a “regular occurrence” unless you have amazing core muscles and your teeth are no longer your own. Full dynamic on DRC is still for “track or Sunday hoon”

I run Vossen HF2s in 21x10.5, ET7 rears and ET11 fronts, with 295/35/21 Michelin AS4s. No rubbing. No issues.

Any chance you could snap a few pictures?

Those don't look like CCB

[doctorbullet]

Correct, not CCB. My mistake, I didn’t pickup the CCB requirement in OPs request.

[allenyao09]

I had 21-inch wheels fitted to 295/35/21 tires

I’m also looking for a set of the OEM 21 inch 10 spoke wheels. Does anyone have the part number? Tried searching but no luck..

Thanks. Will these clear the CCB?

[Nickos1]

Yes. The oem 21s clear the ccb’s.
