Pole for Stoner despite heat concerns

World champion Casey Stoner says he's concerned by the Spanish heat affecting his tyres despite qualifying on pole for Sunday's Catalunya MotoGP.

The Australian set the fastest lap on his Repsol Honda and will start alongside Yamaha's Jorge Lorenzo and Britain's Cal Crutchlow.

Despite his concerns over the high temperatures forecast for Sunday's race, Stoner says he's still "pretty happy" with the result and is hoping for his third win of the season.
