definitive tire, wheel, and offset thread

[s8prtotype]

Just a FYI there is some good deals in that size!

I think they would look pretty good if they could work....

I have yet to see a C5 on 20" wheels that I liked, but beauty is in the eye of the beholder. In my mind, the A6 came stock with 15-16" wheels, so OEM RS6 at 18" is already pretty decent; 19" makes it 3" bigger than a standard A6. 20" to me is Hot Wheels car status.

Alright wheel/tire gurus I need your help. How about an 18x9 5x112 (those all good so far...) offset 38? And they are 66.1 not 57.1. So I would need custom adapters and spacers of what size, or just hub rings? Thanks!

1) Yes, you'll need the hub bore adapter.
2) Grab 5mm spacers (Actual difference is 3.4mm but kicking the wheels out an extra 1/16" can't hurt one bit)
3) Stack them Hub->Spacer->Adapter->Wheel
4) Enjoy a frosty bev'rage AFTER driving them around.

Good info here as always. My goal is to go with a 19x10 wheel if possible, 19x9.5 worst case. I would shoot for the 275/30 or 35 size tire. Now I just have to find the right wheels...........

There's one set of each wheel size and new 275/30's here. General tech forum, but we're also looking for new members to grow with. Feel free to post what you like or are searching for. Always coming across good deals and closeouts.

If you're looking for exotic forged wheels, at better prices, that is in the works as we speak.

Very good to know. The RS6 is a hard car to buy wheels for in my opinion. I'm not sure exactly why but most wheels don't look quite right on it.

This may have been said elsewhere but on page 2 of this thread someone says 30 lbs. They are not 30 lbs. They are 31.8 lbs. I went up to the attic grabbed one of the two extra wheels I have (OE, with factory paint still left on it) and put it on the scale which is a scale for many reasons I trust down to the tenth of a pound. Picture proof. Still on my search for light forged 18s with factory center bore...tough search.

I guess I have the balance weights on there.

This is what you want after you figure out how much spacer you need: https://www.motorsport-tech.com/wheel_spacers.html

Could I run factory tires with this size (the extra half inch wheel)?

Shouldn't be a problem, the section width on a 245 tire is 9 inches so it will be nice and flat.

OE tires are 255/40's, O_E.

(Even the C5-A6 4.2 uses 255's)

Always new the OE stockers were, well, Pretty Looking Porkers.

My flow form forged 19's are noticeably lighter when switching wheels out.

I had gone thru the near agonizing process of finding wheels that I both liked and would fit the car-- and the budget. Nearly all wheels look better when the car is lowered. Vice versa too. It's always a gamble. Practice makes perfect-- one is likely to buy more than one set of wheels over the years.

Been connecting with iForged and Forgestar this week. Really nice wheels that have the quality but not the extreme pricing. Forgestars have caught my eye....

I should be able to provide some very nice deals to get the ball rolling. Still some great tires available on closeout that would wrap a 19" wheel very nicely (see FB forum).

Wait Gary, so I knew you were somehow in the auto biz but, are you a dealer for certain wheels? If so PM me your info.
