Pictured is my 170/80/15 Michelin Commander II rear tire after 9,012 miles. I had hopes of making it 10K but it wasn't to be. This thing is a rag after these miles but still lasted about 2,000 miles longer than my Pirelli RT 66's. You can see it is beginning to get into the cords and I consider it unsafe for my riding conditions which includes a lot of highway riding (see chicken strip) about 40% of which is in heat 95 to 105 degrees and over 70mph. Its a little sad that I can only make 9K on a rear tire but I guess it's the cost of doing business. I rode 18,000 miles last year but fortunately I get this rear tire installed at my local Kawasaki shop for $187 including tax....that's a ride in ride out install so very cheap in my opinion. I have heard people on this forum say they get a lot more miles on theirs (like 15,000) but I have to believe its urban legend or something because this is the best I can do. Great tire though and performs very well in the conditions I ride. I will continue to use them until I hear of something better that is in this price range. I run it at about 37 to 40 PSI.
