Motogp Tire Size

It s insane but this is what we all use.
Motogp tire size. Width and diameter are measured on recommended rim. Tire sizing on a motorcycle like a car comes in 3 numbers. The lower number of tires per weekend was considered a handicap to michelin riders. Dunlop recommends that tire warmers be set at 70 80 c for 45 minutes to 1 hour maximum.
This chart excludes daytona. In 2016 michelin took over as the official motogp tire supplier after seven seasons of bridgestone performing that function. That means the tire is 190 mm wide the height of the tire from the rim is 65 of 190 mm and the rim size is 17 inches. The only motogp team using dunlop tires in 2007 yamaha tech 3 did not use them in 2008 but switched to michelin.
Tire performance degradation may occur if tires are subjected to repeated tire warming cycles and or temperatures times in excess of these. Yes this insane tire specification is a metric measurement a unit less ratio and a us standard length. Tires need heat without which everything fails. Michelin will offer a new rear tire for motogp in the 2020 season.
The season was a huge learning curve for both michelin and the riders. In 2008 the rules were amended to allow more tires per race weekend 18 fronts and 22 rears for a total of 40 tires.
