While a maximum distance of 18 laps for each set of tyres appears quite simple, it is far from it.
It is certainly not a case of stopping on laps 18, 36 and 54 and running until the chequered flag. Things are more complicated than that, firstly by the fact teams will not want to head into the pits when everyone else does, as that opens the risk of traffic chaos. It will be better to stagger pitstops.
