It’s perfect for gravel road, even when it’s wet. On pavement it’s noisy and you shouldn’t have too much air pressure in them otherwise it can feel kinda bumpy and even be slippery. I took special care to have less air and thus more grip in the front than in the back and I don’t have any major problems.

Edit: Also, even with smaller curbs you really have to take care when crossing them, as the wheel slips a lot more easily!
