Martin Brundle takes to the track at Monaco to test a GP2 car on 18-inch tyres as F1 considers moving to bigger rims in 2017.
It was the first time Brundle had driven a GP2 car and his first time lapping the Monte Carlo street circuit since retiring from Formula 1 in 1996.
Pirelli have previously tested 18-inch tyres on a Lotus at the 2014 Silverstone in-season test as the manufacturer looks to make F1 more relevant to road technology.
