Interesting, but the Michelin website is minimally helpful.

www.michelin.co.uk/auto/tyres/michelin-primacy-4#sizes

Alpha values for everything except noise in dB and start date. Rolling diameter TBD?

It's unfortunate that the smallest size is 165/65r15. On the Superbeetle, I run 65-series on the back and 50-series on the front.
