Hi guys,

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

I have found this great offer of Audi A4 8W rims (8W0601025H) with the following specification 8Jx18 ET40, a wheel hub 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.
Best,
Fidan

Perfect fit.

Really? I was not concerned for ET, as there is plenty space on the wheel base, but rather concerned for wheel hub difference as a local tire seller told me that it might shake the car and be loose...

The thing is that I will order them online in Germany to my friend living there, and he will bring them to me by car, so I am not sure if t fits and worth the hassle.

The hub bore on the new wheels is 0.1mm smaller. It is likely just a rounding error, but if anything it will fit the hub tighter. I wouldn't worry about them at all.

Oh right! Sorry for the numerous questions, but is there the possibility of not squeezing in the hub for that small difference as Audi seller is strict on saying this for A4 and we do not garantee if it fits or not.

The hubs on the A4 and A6 are the same.

If it helps, I have discovered that on the base A6 2.0T Models for 2013, the brake rotors and pads are also the same as A4 so that means the hubs must be the same dia. (3.0 models have bigger rotors though)

Fidanh

Thank you guys! The authorized dealer selling the rims says these are for A4 and due to A6 weighting more it would not be designed to hold that wait.

What dou you think? Considering the amount of aftermarket rims, I doubt this is the case.

Wheel should work just fine. Looks at this site, pick a wheel. You will see multiple models that will fit the wheel.
