F1 tyres designed with 2015 “in mind” tested in Bahrain
Pirelli reports the completion of the first in-season Formula One test using 2014 cars. The Italian tyre maker brought around 250 experimental tyres to the test in Bahrain this week; it says these tyres were designed exclusively with 2015 in mind and included eight new constructions and six new compounds. Testing took place over two days, with Caterham participating on Tuesday 8 April and then Mercedes and Williams the next day. A total of 110 laps and around 595 kilometres were covered on the experimental tyres. Only one single variable was tested at a time – a new compound was tested with a current construction, for example, and vice versa. In order to provide a benchmark the teams alternated prototype runs with baseline runs on the existing tyres.
