This is normal, simply because rubber increases the total mass of the car, just remember Kubica's fist race last season, when he was disqualified because of that mistake (not collecting enough rubber). And btw, the tires are always approved, the teams dont get to choose there tires, but they simply recieve the sets from the FIA.jaslfc wrote:after the race there was the radio conversation between kimi and the pits. something interesting was they were reminding him to pick up rubber.. could this be just for precaution coz they were runnin a long stint on the soft compound and they wanting to make sure the tires passed the fia post race inspection?
