Jorge Lorenzo compounded Michelin's highly publicised woes as he finished the Czech round of MotoGP down in tenth place, 40 seconds behind his Bridgestone-shod team-mate Valentino Rossi.

An exceptionally tough weekend for the young Spaniard as he continues to recover from his injury, Lorenzo had to get a special permission to even compete after tyre woes prevented him from qualifying inside the necessary time.

Unsurprisingly, things didn't improve much overnight and Lorenzo was hamstrung in a race that saw the French tyre manufacturer embarrassed by a distinct lack of grip from their rubber.

Although Lorenzo coped better than most as he forged his way up to tenth to score some points and be classified as the second best of the Michelin competitors, he was still almost two seconds off the pace of race winning team-mate Rossi.

Nonetheless, while a number of riders have come out in criticism of Michelin, Lorenzo was relatively philosophical about the situation and has vowed to do all he can to get back to competitiveness.

"This race is a bit sad for me because we have the potential to do a lot better. However considering what has happened this weekend and, above all, the problems with the front tyre, I think we have done almost as much as we could.

"At the start I didn't want to take too many risks and I could feel that the front tyre was getting worse on each lap, but on the other hand the rear tyre was getting better each lap! I know that we have had had problems this weekend but I know that Michelin are working very hard, so now we will try to use the test to make some improvements."

There was some consolation for Lorenzo though as his closest rivals in the championship, Andrea Dovizioso and Colin Edwards, were unable to do much better on similar rubber allowing the Yamaha rider to hold onto fourth in the standings.
