Does anybody know the centre bore size for the 2013 Audi A6 2.0T? Some wheel/tire sites that say it's 57.1 mm and some says it's 66.6 mm. I've contacted my Audi parts manager and she didn't know and I sent an e-mail to Audi Canada and they didn't know. I believe it is 66.6 mm for the C7 and 57.1 mm for the C6 (pre-2012). I'm looking for after-market rims for winter. I think that both would fit but I would prefer avoiding the use of spacers.

It is 66.6 mm as far as I know.

66.56 (or 66.5)

Thanks for the info. I'm putting Replika wheels (www.replika.ca) on the car for winter (R115A 17x7.5, 35mm offset, 66.4 centre bore) that look very similar to the OEM wheels, along with Nokian Hakka R2 225/55 R17 101XL tires. They have an option of 45 mm offset but I was told 35 mm would be best.

revised... was advised to choose 45 mm offest for winter rims to give more room for snow/slush between tires and fender.

Sorry for bringing up the old thread but what is it, 66.5 or 66.6 then?
Should I buy 73.1 to 66.5 or 73.1 to 66.6 rings for my new 3sdm alloy set?
Car is 2013 a6, 2.0T.
Thanks!

You'll want 66.6. The actual bore is 66.56, so 66.5 would be too small.

Thank you Sir!

I would be smart to have two sets of hub centric rings. They sometimes break when taking them off the hub if they don't stick to the wheel.

Hi guys,

I am planning to upgrade my 16 inch rims to 18 inch rims for summer tires. The factory rim size for my Audi A6 is 8Jx18 ET39, I assume a center bore of 66,6.

I have found this great offer of Audi A4 8W rims (8W0601025H) with the following specification 8Jx18 ET40, a center bore of 66,5.

I need an expert opinion on this, if these new A4 rims would fit to my A6 C7, with 1 mm difference on ET and 0,1 difference on wheel hub?

I would appreciate your feedback.

I'm not an expert and I don't know if A4 wheels fit on a A6 C7.

The difference is .1 mm, not 1mm. About the thickness of a sheet of paper.
