Well, this all started from an arguement I had with a buddy over what tires were the best. He is a Dunlop D952 fan, and you could not take away my Maxxis Maxxcross IT rear for anything else. You can keep the IT front. I got the Maxxis IT's on the fact that every one here raves on about them. Who was the one that said the IT front tire was good? They deserve a good whooping! Anyway, long story short, we both got new tires mounted, myself with the IT and my buddy with the 952. We both use the same gearing (14/50) and 120 size, so we decided to swap rear tires. Keeping things consistant, we tried a few different tire pressures, but we both liked and settled on 12 psi. The first thing I really noticed was that the 952 would really hook up! I thought my IT was great, but this tire rocks! I feel out performed the IT everywhere except the real hard rock and shale stuff. I put this down to the IT having shorter knobs and closer spacings than the 952. The 952 is the master of sand, gravel, mud, but squirms around a bit on hard rock and shale. The IT is better on the hard rock and shale, but If this is all I rode, I wouldn't be using an IT anyway. The wear of both rear tires for the day was the same - none. I have found the Maxxis IT front really crap, so I have been running the SI front. Way better than the IT. This thing actually grips. My buddy has the 952 front so we decided to swap front wheels too. Just by looking at it, you could tell it was going to be better. In the first 5 minutes, my buddy had a fit and demanded his front tire back! I can see why! The 952 is a lot more aggressive than the SI front, again with longer knobs and more of them to provide better bite. At the end of the day, my next rear tire is going to be a Dunlop D952. Definately worth the extra $10 for the increased grip with the same wear as the IT. I already went out and got the 952 front tire on my bike. I just have to wear out the rear, but as you know, that could take some time. So, if you ride mostly rock and shale, stick to the Maxxis IT. Either that or try a trials tire! If you ride anything else, go the Dunlop 952. You won't regret it!
