Formula 2, the feeder series for Formula One, will switch to lower-profile tyres and 18-inch wheels next year to prepare young drivers for grand prix racing, which is due to make the change in 2021.
Formula 1 sporting director Steve Nielsen said the intention was to bring Formula One, Two and Three as close as possible.
“Formula One will benefit in future, and Formula Two is a good test bed,” he said.
Tyre supplier Pirelli currently supplies Formula One with 13-inch tyres.
Pirelli’s Formula One head Mario Isola said he wanted to start testing the new tyres in September.
