Its a nice tire, been driving for a year and very little tread wear. Fuel efficiency and road noise wise its quite good as well. Only downside is that I don't think its traction is too good. Recently while driving at around 120 km/h, the guy in front of me hit brakes hard. I applied braked hard as well, while I didn't feel much braking force the ABS kicked in and tires screeched - implying that they skid too easily. Maybe I should have gone one size larger.
Still they are much much better than General ones. In this price class, I think that's about as good as its going to get, no idea about how good Yokohama ones are.
