Pirelli will be named as Formula One’s sole tyre supplier from 2011, according to reports.
The Italian company has been locked in a straight fight with Michelin to replace Bridgestone and the Formula One Teams Assocation (FOTA) is believed to have named Pirelli as its preferred choice.
According to Autosport, the FIA and Formula One Management (FOM) will work with Pirelli on commercial terms and a deal could be announced over the weekend.
The deal is expected to see F1 continuing to use 13-inch wheels, rather than the 18-inch rims Michelin was proposing, and there will be no tyre war until 2013 at the earliest.
Pirelli last supplied tyres for the sport in 1991.
