Rain hits first British GP practice

Weather conditions are far from ideal at the former WWII airfield this morning, home of Silverstone. Persistent rain fell for much of yesterday afternoon and evening and further bands of rain have crossed Northamptonshire this morning.

Wet rubber is the choice for first practice as once again the weather disrupts the best-laid plans of teams looking to evaluate this weekend's selection of the medium and hard Pirelli slicks.

This is also bad news for the opportunity to test the modified construction of hard tire, closer in characteristics to the 2012 rubber, which had been planned today.

Pirelli has ruled out racing the modified Kevlar-belted tires before the Belgian GP after failing to get unanimous support from all teams, but this will further dent the evaluation of that rubber. Autosport.com
