Fernando Alonso believes F1’s switch to Pirelli tyres will lead to more exciting races in 2011.
"The tyres are not lasting as long as (the Bridgestone’s did) last year," the Spaniard said in an interview with EFE news agency.
"After 15 or 20 laps they run out of life," added the Ferrari driver.
"I think it will change the way races are run this year; there will be different strategies and more pitstops," said Alonso.
"I hope this is good for the show, but for the teams and the drivers it will be a little more stressful."
