not me.Every tires are useless as hell.
1)Medium are useless because they were OP back in the days.
2)No it wouldn't.Hard tires are abused 'cause they degrade slower and heat up slower meaning they can be used in higher push level = damaging the engine more.
3)That means Hard and Medium will become completely obsolete.Meaning the only usable tires are Soft,Super Soft and Ultra Soft.With the 2017 tire wear,Soft will become the new Hard,Super Soft will become Soft and Ultra Solft will play the same role as current Super Soft
Now all the tyres will be ONE step softer in order to prevent the boring 1-Stop races
