So I did probably close to 75 miles in the dirt today with the TKC's and another 120 miles on pavement. They actually did really well in the dirt and sand and I was surprised at how streetable they were on the pavement. The 17" front wheel is still a huge limitation in the soft stuff, but hard pack and gravel it eats up like nothing else. The group of guys I was riding with today are a little unbalanced and have somewhat of a death wish so I can tell you that these tire get squirrelly on the pavement above 120mph. Below that they were great, even leaning into corners around 90mph. You definitely can't lean them over near as far as PR3's or whatever other street only tires you might use, but they do a good job of telling you where the edge is before you reach it. Most of the back roads we were on today were orange grove trails with pockets of deep sugar sand, and when you come up on those you're still gonna get some pretty good pucker factor if you enter in too fast, but on the D616's I used for the TLH I pretty much had to almost come to a complete stop before making any hard turns in the sand, where these allow you to carry a little speed. The long sweeping dirt turns is where these really shine on the MTS, I used to always have to slow down a bit for fear of the front end stepping out, but you really feel planted with these, much easier to steer with the throttle on these than with other tires I've used before. I've got about 6 hours worth of video I need to edit down, but once I'm done I'll post a short clip up so you can see what I was seeing. Between the TLH and today that's about all the dirt riding experience I have, so I'm sure a more seasoned rider could really tear it up with these.
