Horrible horrible tyres.
The tyres produced a 2-3s per lap difference between used and new tyres, as they are designed to do in order to create strategy options -- this allowed Magnussen in a HAAS to snatch the fastest lap. They worked well.
Those on new tyres such as Norris, Gasly, Giovanazzi and Hulkenberg were able to go on the attack passing cars in the Singapore grand prix, producing plenty of action.
