Bridgestone is to add an extra compound of front tire for MotoGP riders to choose from. After complaints from the teams over problems at some circuits, Bridgestone has responded by expanding the number of front tires allowed for each rider from 9 to 10, and adding an extra compound of front tire to help deal with differing conditions.
The change to the allocation had long been a wish of the MotoGP riders. Though Bridgestone's two selected compounds performed well under most conditions, a sudden drop in temperatures sometimes left riders and teams struggling. The problem was most pronounced in the morning sessions at circuits like Valencia and Aragon, where temperatures can be very cold. There were several front end crashes in those morning sessions, as tires struggled to get up to temperature. Adding a softer tire should make the morning practice sessions safer, and allow teams to work on setup without compromising safety.
The added tire also makes Bridgestone's job a little easier. The tire firm already produces rubber which works under an exceptionally wide range of temperatures and conditions, and expanding that to handle the more exceptional conditions was an expensive business. Adding a special softer tire for cold mornings means they can optimize their tire selection for expected conditions in the afternoon, giving teams better tires for the race.
