Tinken
Husqvarna
Pro Class
I had a similar experience with the Pro FIM front on my 610. I really liked it in the softer stuff (NJ sand & loam riding), but one day of riding gravel fire roads and rocky singletrack in PA tore half of the side knobs off. Since I use my bikes in both types of terrain regularly, I can't tolerate a tire that self destructs in rock. Too bad, because the tire was pretty good otherwise.
I have a XCMH rear on my DRZ (Colorado bike), and it's been satisfactory so far. I used it a little bit in Moab and a bunch of miles in baja at the 1000 this year pre-running. It seems pretty tough and hooks up fine. I will note that I'm not super picky about rear tires, as long as they last and hook up ok. I am much pickier about fronts...
Which tire did you use on front in baja?
