I emailed Michelin and got a detailed response from Michelin Girl named Lori:
11. Subject = US-EN-Michelin&Technical questions about tires
12. Message = What is the measured outside diameter of Michelin Road Pilot 3 size 160/60ZR18 ?
13. Vehicle Year =
14. Vehicle Car Maker =
15. Vehicle Car Segment =
16. Vehicle Option =
---------------------------------------------------------------------
Thank you so much, this is a very good question. After talking with one of our senior representative we have come to this conclusion. The nominal diameter is 649mm and the maximum diameter is 663mm. Meaning when the tire is cold and not been rode on, it will be at 649mm and once rode on and heated up the maximum diameter will be 663mm.
I hope this helps!
We appreciate your business and thank you for choosing Michelin.
