So, I have used one of these tires for my unicycle. They are the hard kind. My opinion, usually 100 psi is awesome to put on, but usually the pressure in any tire I've had doesn't tolerate quite that high pressure to practically keep it up. The tires that can ever be pumped up to that I prefer for their durability. The tire that my uni came with was pathetic. And, it came with a weak tube that went flat two moments after I pumped it up.I went out of my way to put on a measley 60 psi tire, and found after riding with my uni attached to my backpack on a different bike (a road bike), that the problem was that the inner tube had been bulging through a huge long hole in the tire. So, what I'm saying is that this tire gets the job done because it has the job requirements fulfilled to do my stuff on my unicycle. And, I'm heavy, 180 pounds often. The other thing that I recommend is purchasing a thick tube if you, like me, want to avoid flats with rough rides. Thank you to the people that make good tires like these.I guess it's not high-end, for hardcore professional riding, but it is really tough, which is what people like me probably want!
