Sorry for another tire question. I searched for Michelin AC10 here and most of it was how they are not made and availability is limited. I found tires some on-line. A friend was using one for the first time this past weekend. Only tried it on pavement & gravel so no real off-road feedback. But it did look good and from behind him it appeard to have good bite. Any opinions on the Michelin AC10 for 60-70% off-road? Thanks!
