Seems strange that there are mixed reports... I have found that, especially in that horrible sticky mud, the tread doesn't clear amazing well on mine, but that said, its no worse than a Minion. The sidewalls are exactly the same as the other Dual Ply Maxxis tyres, and I've not had a single puncture yet. The wear rate is something I've been really impressed with on mine - its about 6 months old now and has only half gone! Personally, I think they're definitely worth a try if you're looking to get a new tyre any time soon. As for compound: if you ride mainly street go for the 42/50, and mainly natural 40/42. Cheers Adam
