I just changed my front Shinko 009 at 13,100 miles. It appears I will get about 14,000 out of the rear. They are ZR~W rated Toursport tires instead of Sporttour. I've ridden every kind of pavement, green grass, bridge grates, gravel, and weather there is from Nov 15 till now. I just bought my
2nd set and have no complaints.
Some who have never used them are worried they don't cost enough to be safe or good. If a tire company molds that ZR~W in the tire size then you better believe it will be safe when you do 130mph on your Hornet.
I don't care what they do on the track, because I have no intention of ever running on a track.
