Formula One's tyre supplier says this year's less durable tyres will make for a more exciting season, with more pit stops.

Pirelli motorsport director Paul Hembrey says shorter-lasting tyres mean last season's one-stop races for some teams are long gone.

Hembrey says "in 2012 we saw a tendency through the season toward one pit stop and we want to go get back to two to three, (but) you won't be seeing five or six pit stops."

Several drivers voiced concern over the tyres' quick degradation during preseason testing at the Catalunya Circuit last week. Hembrey says that was due to abnormally low temperatures.

Tyre choice and speedy pit stops are key elements in F1.
