These are pretty great little tires for the price if the fit your needs. I got them more as an experiment to use my fat tire ebike as more of a road bike than a mountain bike. It worked but i prefer the off-road tires for the kind of riding I do.
What these tires are good for...
1. Low rolling resistance and run smooth an quiet.
2. Low pressure so they have great bounce and shock absorbtion.
3. Very grippy on road surfaces and ok on grass. Also grip well in the wet.
What I didn't like...
1. I go between off road and pavement back and forth all the time. For me its easier to ride on pavement with MTB tires vs ride with road tires offroad. These tires are great on smooth pavement but are a little scary in turns if that pavement has gravel or sand on it. Ultimately these make the bike handle more like a BMX than a mountain bike which may be a plus or a minus depending on the rider.
2. The rubber is much softer than I'm used to but I'm more concerned with the grip. Im used to MTB tires having a little bit of slip on paved surfaces and bite in the dirt. These tires grip so good that when i do an aggressive turn on pavement where my tires normally have some give or slip, these are glued to the road and if not used to it can cause you to over steer or over correct.
If i were only riding on pavement or using the bike as a beach cruiser I would love these tires. Especially if i had to ride often in rain or had to ride bumpy pavement. The low volume bouncyness and the sticky traction makes for a real smooth ride. I'd even say that the increased efficiency makes my battery last longer however its hard to say if thats because of the lower rolling resistance or if i just ride slower with these because I'm afraid i might over steer and crash. I think if you're not an aggressive rider and just use your bike as transportation and want the smoothest ride possible these are good for you. :D
