F1: Lotus to test 18-inch Pirelli tire

From GMM

Pirelli will test a much lower-profile tire during next week's post-British grand prix test at Silverstone.

F1's official tire supplier, whose public profile has been much lower in 2014 as drivers label its new approach as "conservative", said the 18-inch tire will "showcase the way that formula one could look in the near future".

The Lotus team will be running the novel tire design.

"Larger wheel and tire sizes reflect modern market trends," Pirelli said in a statement.

The current F1 tires have a 13-inch profile, unlike rival categories like GT, Le Mans and Formula E.
