i was having some trouble finding a front tire that performed well in mud,muddy rocks,and rock all at the same time. i had tried the maxxis IT,great tire just sucks in the mud. tried the trelleborg maxi-grip great in the mud sucks on muddy rocks. some other people have rode my areas with s-12s,m-12, mt-18,756 etc and it was always one or the other none could do all of those well. i just put the SI on for tomorrows ride and rode it around the back 40,the front end feels like its glued to the ground(its rained here for 3 days !) it blows the trelleborg away in the mud and handles the rocks just like the IT !!! may have stumbled onto the perfect eastern woods tire. the back tire is due out this month, i'm gonna try one of those when my tenmaster wears out !!!:cry: will let you know how it works out on high speed trails after tomorrow.
