Thank you for the info re tyre size.
Totally agree on the white worm, it has destroyed two of my existing alloys.
Are there any OEM GTI, GTR, R 18 inch powder coated alloys?
There’s the GTI version of the Sevilla alloys - dark anthracite grey with a red pinstripe around the rim. They seem to divide opinion; a bit of a ‘Marmite’ wheel. There’s also the Rotary (18”, anthracite grey) and Motorsport (available 18” black, but available in anthracite on on some websites), both are available as VW accessories, but not as factory fit alloys.
I had the Rotary’s on my mk6 GTD - not as a winter wheel, but for all year round use.
Rotary and Motorsport alloys are both on the website at the link below, along with a number of other powder coated / painted alloys. Unfortunately, I don’t think they ship to the UK, but the website includes details of each wheels’ part number so should help you source a set if you find any you like. The wheels on the website include details of model usage, so you can see which wheels are suitable for the mk7 / 7.5 GTI.
