My husband loves the tires. He can tell that these tires work better than the other ones he’s had before.

More comfortable than true mountain bikes tires and more grips than road bikes tires.

Nice fat tires for my ebikes. Makes lower noise when riding than my spiky mountain bikes tires and grips better than my road bikes slick tires. They are a great compromise since even as I ride mostly on pavement, sometimes I would run into sands, muds, dirt, and loose rocks that these would work great. These tires seem thick and durable in construction. Tread pattern is a compromise between the smoothness and quiet of a road bike tire and the grip of the mountain bike tires. Note that these are directional tires. So take care to mount them in the correct direction when installing.

Affordable toughness for your ride

I swapped out my old rubbers for these and was pleasantly surprised. The price is friendly enough that you won’t have to skip lunch to afford them, but the feel and durability scream premium. They mount easily, the tread grips like a handshake at a family reunion, and after a few hundred miles they still look fresh. It’s rare to find something that makes your bike feel safer and your wallet feel untouched. Give them a spin—you might even start making excuses to ride more.

Heavy Duty Thick Tires

These tires are well worth the money. Super thick, unlike the rest. I have rolled over everything possible. No flats, rips, or tears. You need to take the time to balance the tires. If you don't, it’s wobble city. The noise of the tires rolling, is very low.

Like the brand

I have had a devil of a time keeping my tires from getting flats this year. I got back into biking (actually triking) this year, and the desert is not kind to inflatable tires.Since I needed 3 tires (the original OEM ones are low drag street tires, really not suited for my environment) I had to get two sets of tires. I like this makers tires YUNSCM as they are very easy to mount and dismount from my rims. I have been putting a set on the two rear tires, and then rotating a different set on the front.So far, I have discovered the TPU inner tire linings, and self sealing inner tubes are helpful, but not perfect. Since these have a "soft steel" whatever that means bead, they're pretty easy to get off the rim, even on trailside allowing for tube patching. Luckily only had to do that once.These are holding up so far, and the pattern seems to have decent grip on dirt and gravel.Can recommend, good brand and no problems with installing.
