Bridgestone bosses have, predictably, said there was nothing wrong with their tyres at the Austin MotoGP round despite Scott Redding, Valentino Rossi and Hector Barbera suffering severe front grip loss in the race.

All three riders totally destroyed their medium compound front tyre with Redding crashing and Rossi having to slow down by some three seconds a lap before the race had even got to half distance.

Race boss Masao Azuma admitted he was puzzled by the problem but added Bridgestone would have to look at various parametes including bike setup, track conditions and riding style to solve the issue.

“The high abrasion on the right side of the front tyre that some riders experienced during the race was unexpected. There are some sections of the circuit that are quite demanding on the right side of the tyre, but our compound allocation for this race was designed to meet these demands,” said Azuma.

“We need to look at all the variables including riding style, machine character and the track condition during the race to work out why we had such high levels of abrasion during the race, and why some riders were affected more than others.

“We can say with confidence that the tyres were not in any way faulty, just that the operating conditions during the race were a lot harsher when compared to last year and the practice sessions earlier in the race weekend.

“As we didn’t see these very high levels of abrasion last year or during practice and qualifying this year, the tyres and race data from the Americas Grand Prix will be analysed at our Technical Centre so that we can find out why this happened.”
