After more than 20 kilometers of test riding the Grifter, I must say I am impressed with the duties I've intended for it. The wide size of the tires makes the ride a bit more comfortable than the stock 20x1.50 tires that came with the bike. Loose road particles such as gravel, small rocks, or even litters can be run over with confidence. Transitioning from road to sidewalk or ramp or any kind of unevenness is something to be cared less about. The bike rattled less.
You can't use all the width of the tire on the folding bike. I can't turn as hard as I can on BMX or Road Bikes. The tire shoulders do not contact with the ground. The photo below shows that the shoulders have a brownish dirt while the crown area is relatively clean.

Even though the Grifters are not slicks, these tires are grippy on various kinds of pavements, even smooth concrete. This is particularly good because I slipped once on road bike tires. It was messy. The big threads may have contributed to grip while dry. I would still have to test it on wet surfaces. These tires are also noisy. Maybe not as loud as the hubs but definitely audible even on easy rides. I cannot attribute the noise to the thread design as I have no means of measuring it. Another thing that bugs me is that road particles can get stuck inside the threads.
