made punctures much more common (pictured

Italy). The running order for the first day is governed by championship position, with the championship leader running first on the road. For every other day of a rally, the order is decided by the previous end of day classification (with the leader on classification running first). The term '
leg' has been replaced by 'day' in order to sound more understandable. Extra 10-minute service prior to the finish podium has been added, intended to allow the service park to remain an attraction until the end of the event. With the switch to
Pirelli tyres,
tyre mousse (along with all anti-deflation devices) has been banned, and fewer compounds are available. Also the teams aren't allowed to modify tyres by themselves (e.g. by making additional cuts) anymore. At the
first event of the season, the available tires were the soft slick DS tire (
Pirelli PZero The same snow tyres were used in
Sweden as well. Later on loose surface tyres were introduced:
Pirelli Scorpion, available in two variants – hard compound for abrasive surfaces, such as roads in
Mexico or
Greece, and soft one, for more muddy stages as seen on
Welsh event. Tire walls have been strengthened in order to endure long, rough gravel stages often full of sharp rocks. The tread on
Scorpions is asymmetric and directional, as it has proven more efficient during the tests. == Calendar ==
