Nico Rosberg has welcomed the tyre-usage rule changes in formula one for 2016.
The governing FIA and Pirelli announced last week that teams and drivers will get more freedom next year, as the range of different tyre compounds available at each grand prix is increased from two to three.
The details of the rules, however, caused some confusion, with Lotus driver Romain Grosjean admitting: "I’m glad I have an engineer to help."
But 2015 runner-up Rosberg told the Austrian broadcaster ORF that he likes the sound of what was announced.
"I think it has been very well thought through," said the Mercedes driver.
"It is good to get another variable to make it both more interesting and difficult. This is great, because the tyres are very important for the excitement," he added.
