I bought these tyres for my non m but they were slightly wide. They have done less than 70 miles so are basically new. Bought for over £500 from Camskill a couple of weeks ago. I know i'm going to have to take a hit so am going for £400 collected. Both manufactured by Michelin in March 2016. They will also be going on eBay.
Inner to outer:
