I love the Duratracs, on my second set, but they have their limits. And their major limit is sidewall durability off road. The "weak" sidewall (compared to dedicated MT like a KM2 or any Interco) is the result of the soft rubber compound, which is required to achieve the "snowflake" rating for winter use. With best available current technology it is impossible, to develop a tire that will perform very well in all the conditions: off road (durability), on tarmac (wearability), and on snow (pliability). Pick two.
A lot of guys I know in central america run bias plys because they are cheap and they don't break (but ride like crap on tarmac...). Duratracs were designed to fill a niche in the off-road market, and they do it very well, but they do have limits: barely safe in snow and vulnerable side walls. But they do wear like iron. Design is always a compromise of requirements...
Wow that price is near double the US! Thats what we pay for Mich XZL, when we can get'm over here.
