After looking at the wear bars on my rear tire, looks like I'm right at them. I want to say it's been 10,000 miles on it. They are Michelin City Grips. Are there any tires that would last longer? Is this about average? I had a Diablo on it when I bought it and really didn't like it. So, any suggestions? I'm also looking at the Michelin Power Puer SC. In looking at the tread design, looks like it would wouldn't have as good of traction? But, it looks like it would be good for highway riding. And that's mainly what I do.
