Generally, Bridgestones perform better in wetter, colder track conditions; otherwise it's Michelin.

Michelin collaborates with each team to which they supply tyres. They offer several tyre designs, and it's up to the teams to choose which one to fit in their cars. Bridgestone simply concentrates on the Ferrari chassis, thus offering fewer tyre designs. The other Bridgestone-shod teams will have to be lucky to come up with chassis designs similar to Ferrari in order to accommodate the tyres. :evil:
