Ironically, people still think Button uses his tyres less hard than Hamilton, but, on the Bridgestone that may have been true, but on the Pirelli tyres, there isn't enough data to compare them against each other yet, and there have only been two races worth of data, information to go off anyway, so it just proves, ever since China 08? or 07? When he went into the gravel trap that people just assume Hamilton abuses the tyres alot.
At least that's where I think it stems from, and I'll admit, I was one of those people who believed Hamilton to be harder on the tyres, but like I said, on the Bridgestone that may be true, the Pirelli's are a different ball game. Considering Button complains like hell about tyre wear at every race, in every session he drives in, and Hamilton just shuts up and gets on with it (when in the car at least) maybe people assume Jenson can manage tyre wear better than Hamilton...
OT : Seriously, is it just me or is almost every radio message of Jenson just him whining like a girl? WE KNOW YOU CAN DO IT JENS, JUST STFU AND DO IT. STOP WHINING ON THE TEAM RADIO LIKE A GIRL. "THE REAR TYYYYRESSS ARREEE GRAAIIINNNING LIKE REALLLLLY REALLLLY BADDDDLLYYYYYYY" Man it gets old.
