I'm one for two getting these to stay inflated. Front tire is fine but the back tire despite staying inflated for 24 hrs in the house has never made it more than 2 miles on the trail. Many similar reports with only a few success stories on MTBR. Steer clear of these if you want a reliable tubeless experience. I've executed the full Stans sealant process on a Mavic 819 rim including days of laying it sideways and shaking it every few hours to ensure all holes can seal. A few miles a on the trail always opens new ones. My experience with other tubeless ready tires (GEAX TNT) was flawless and reliable for 4 yrs....
Traction is excellent but only under 30 psi. Unfortunately this is also about where they start to get squirmy under a 170 lb rider. I'm debating now whether to pursue warranty for the flaky tire or just sell them to a friend that runs tubes.
