OK , most of the other reviews are for the older version of this tire. Older took higher pressure. This is the foldable, dual compound version that is SCT tubeless sealant compatible. Pressure rating 30-50 psi.
I was able to mount the tire on DTSwiss rims without sealant with a normal JoeBlow pump. I wiped the tire bead and rim off with Windex beforehand. Held 40-45 lb pressure for a week. Then added sealant through valve. Tire good for hardpack and asphalt getting to the dirt, and is fairly light.... weighed about 650-670 gr. I would buy again.
Great tire for interurban trails, roads, gravel roads, and moderate MTB. If you are riding all sorts of terrain this is the best tire I have found. Yes, it will wash out a bit on gravel, but all tires will.
Excellent traction on hardpack trail with dirt 'ball bearings' in the corners. I usually pump these up to 75-80lbs for trip to the trailhead, sometimes 15mi on pave, then drop pressure to 35lb for the dirt. The sidewalls are a bit fragile for rock garden riding, but the tread wears well, and they are superior to all other heavy tread tires in the rock-hard dirt of summer.
Great tire for hard pack. Grips great on both front and back again on hard pack, but the front kept washing out in looser conditions, so I changed the front tire to one with a more aggressive tread. Kept the small block 8 on the rear and works great
