I've done a lot of searching on this forum, and have found a lot of recommendations towards the Maxxis SI or IT tires. I currently have the stockers on my 05 450 (that front tire can go die). Either way, it seems that looking on Pirelli's site, and elsewhere, that the DOT doesn't care what tire you have up front, just the back? Pirelli's catalog shows all of the front tires being NOT marked as "not for highway use", and it shows a few of their models as being marked DOT. Is this the case? I have a street legal wr450, which doesn't see much road use (its more of an insurance thing). But, every now and then I like to ride it on the road. I was wondering if anyone had ridden either one (perferrably both!) of those tires above? It seems that the Scorpion Pros don't make much mention on Thumpertalk (at least not in the wr450 forum). They seem like great tires, and they are DOT, ISDE tires. Just not many is recommending them. Also, most of Indiana is mud, but there are some hard pack clay areas as well. Does the Maxxis SI do ok on hard clay, or does it really suck there? What about the Maxxis IT in the mud? I don't think there can be much worse that stock, so either choice will proably be better. Just trying to make an informed decision. Thanks for the feedback everyone, M.
