Thanks for advice just put on the Dunlop 606 and i love it. What a difference a new tire make. The stock 603 lasted 2500 and that was 1000 miles too long.

 

I like the Kenda 270,s I have had the trackmasters,but they were loud (road noise) most of my friends like the 606,s they are a great tire also I,m on my second set of Kenda 270's been up every mt. trail on them right behind the guys on the 606's not a problem
