Hope someone can help, i'm looking at buying somes wheels with winter tyres from another forum member but want to know if they will fit my B7 RS4.

Ronal 8" x 18"
- Part #: 8K0 601 025Q
- PCD 5x112
- Offset ET47
- Centre bore 66.6mm

Will these fit?

Going snow hunting in Febuary through the Alps and want to be prepared, many thanks.

From my limited knowledge I would suggest that you will need spigot rings to change the centre bore size (the b7 is 57. Something!!)

Also the offset is very high so will sit well inside the arch. Spacers may be required perhaps?

Not sure if you will have caliper clearance issues with that offset on 18"x8"s too?

Thank Richie, I think I do need 57.1mm spigot as the seller mentioned that to, thanks for the reply, now I just need to know if they will clear the calipers???

I have Kahn 18x8 et33, and there's only a couple of mm radial clearance from the front calipers. My guess is you will need to try fitting them and see, or get someone who has tried them to fill you in.

With that amount of offset, you might have axial clearance issues as well, but a set of spacers would likely fix that and the hub bore issue. BTW, your RS4 hubs are indeed 57.1mm, and the OEM 9" wide wheels are et29.

HTH.

OEM winters which clear the calipers are 7.5 ET 21 the ones you are looking at are 8 ET 47. This will give you 32mm less inner clearance so I would say they will not fit.

I have the A5 equivalent as my winter wheels and they fit but only just. There is only just enough space for the caliper and I have a spigot ring because of the bore different. There's a bit of a difference in the offset and they are a bit wider. I would try before you buy if you can.

ET 29
PCD 5x112
8.5J x 18
66.6mm

Standard wheel is 9J ET29, so would need 30mm spacers to sit the same at the face, and at least 5mm to sit the same inside. I'd imagine you'll need spacers to clear the calipers anyway, but that's much more trial and error unfortunately as spoke design plays a big part.

And you'll need spogot rings as people have said.

Maybe see if these are still available - they would fit !
