MotoGP riders are pushing for Bridgestone to revise its 2013 tyre supply, so that both rear compounds offered at each event offer a serious competitive choice.
World champion Jorge Lorenzo
confirmed that the issue was discussed during the riders' safety commission meeting at the Spanish MotoGP.
The Yamaha star explained that, at the three events so far this year, the softer tyre has performed much better than the harder, effectively removing any choice for the race and leaving riders with fewer sets of competitive tyres over a weekend.
So far this season, only two riders have chosen to start a race with the harder compound rear.
“Let's say we [the riders] are a little bit disappointed, in that we only have one 'good' tyre in almost every track [so far],” began Lorenzo. “This year the hard tyre is not working for almost every rider, so people are using the soft in every session.
“When we try the hard it is really slippery and there is no benefit. We would like in the future that Bridgestone gives two tyres that work really well for everyone. For example, use the soft one for qualifying and the hard one for the race, would be normal. At the moment that is not happening.
“I think we need different types of tyres. The soft one is not so bad, but the hard one at this moment is not working. I don't know if it's not the same, let's say, 'quality' as the soft one but at the moment almost every rider doesn't like it. We need more tyres because if you only have one [that works well] it is difficult to finish the weekend.”
Lorenzo was speaking on Saturday at Jerez. His comments were backed up when, as in Qatar, every rider went on to use the softer rear compound in the race - despite a track temperature of almost 50 degrees.
Bridgestone's chief engineer Masao Azuma said that the hard compound had been brought to Jerez in case of such high temperatures, but that the reduction in edge grip prompted riders to use the softer compound.
“With such high temperatures, it was expected that some riders would select harder rear slicks for the race, but the greasy track conditions meant riders chose softer rears to give them the highest level of cornering grip,” he said.
