Tyre compounds available:
Front: Medium, Hard.
Rear: Hard, Extra Hard (asymmetric)

The asymmetric rear Bridgestone slick tyre performed well during the first test session in Catalunya which provided the hottest track temperature of the season, even higher than during the pre-season Sepang test in February.

During the session almost all of the riders tested both compounds of front and rear Bridgestone slick, and those finishing at the top of the timesheets used the harder options (the hard front and extra hard rear). The top three, Fiat Yamaha's Valentino Rossi and Jorge Lorenzo and Ducati Team's Casey Stoner, all went faster on this combination.

Both the hard and the extra hard compound asymmetric rear slicks comprise a soft compound left shoulder, specifically designed to provide optimum grip at a lower working temperature as the nature of the Spanish circuit uses the right side of the tyres much harder than the left.

Following a request from Dorna, Bridgestone is supporting a nineteenth rider on the MotoGP grid for the Catalunya Grand Prix. Hungarian Gabor Talmacsi makes his MotoGP debut this weekend with the Scot Racing Team.

"Even with the hottest track temperature we have seen this season our tyres delivered good consistency and durability. Most riders started with the softer options (medium front and hard rear) and then ended the session on the hard compound front and the extra hard rear. The track was quite dirty at the start of the session and got cleaner throughout the hour so this helped improve the times towards the end.

"We had no problems with grip through left - and right-hand corners and the riders had a consistent feeling throughout the lap so this shows that our asymmetric tyres are working well here. There are two very long right-handers at this circuit which use the rear tyres very hard and in these we see high tyre temperatures being generated, so this is the primary reason we need to use harder compound rear Bridgestone slicks this weekend."
