Does anybody have any input on the 952, or the Maxxis IT. I mean I have heard raves about the IT, and I am still running the stock 739's on my 426. My cousin rides an XR650r and we have been trying to figure out which one is a better tire. I am sure they both great tires, but I am just looking for input on hookup, and overall life expectancy. He burns through a new tire every time the throttle is twisted.
