I’ve searched extensively on this (on the forum and internet) and not found any single source of this info so thought it would be good to start something.

Ok, I’ve given the game away in that I’m after the Rotor/V-Spoke weights but we could build this into a bigger list if we all contribute what we know.

Just a small point, but the RS6 20 inch wheels you are talking about above were not a winter wheel, they were the standard all seasons wheel. There was a separate winter wheel which was also 20" but it was only 8" wide and looked similar from the side except completely flat.

I know Mike hence the quotes. Many, wrongly, call them that. The 8” are plentiful too.

What should they be referred to as? I hate calling them that as it perpetuates the error.

Added A6 Rotor and weights from look up site.

I'd just call them the RS6 standard 20" wheel. Most people refer to them as the dished ones.

Yeah that sounds better Mike. Amended.

Don’t forget tyre weight too, this gets overlooked. However the standard 19’s look considerably lighter than either 20” offering. I would love to have a drive in a car with 19’s and ramics with all that saved unsprung mass!

Do you have any figures to suggest there’s a big difference between different radial 265/30x20, say?

Genuinely interested to see proof that some tyres are lighter than others.
