Its time for both my bike (04 WR 450) and son (02 TTR 225) to get new tires. We ride in the Oregon, mainly on government trails. Most of our riding boils to going thru mud, slick clay and rocky hillclimbs and descents. I have heard alot of good praise for Maxxis tires. Was thinking of running a Maxxis SI on the front with the IT tire on the back. My front end tends to wash out a little so was hoping the SI will help and the IT tire on the back wont get as chewed up by the rocks as the softer tire would. Last night, I read a review in Dirt Rider about the IT tire. Basically, they said it was a good tire for the money but once it wears down it has a tendency to dig in and spin when momentum is lost. I realize their is no perfect tire. Always a trade off between performance and tire wear. However, I wanted to get some more feedback on tires before I purchased anything. Before Maxxis, I was leaning towards running Dunlops. So given the conditions I ride in, can anyone please give me some input. Thanks for your time.
