Very good and grips the road well.
I have forgotten what it's like to get a flat tire, it doesn't feel anything.
Of course, on the downside, there are vibrations, it becomes very harsh on potholes, but still, it's well worth the money.

After two months of testing, very good on the road. In terms of vibrations, it is only a bit harder than the regular one, it resembles an air tire, fully inflated. I don't see any disadvantages compared to regular ones because, in any case, vibrations are more a matter of lack of suspension and the size of the scooter's wheel, about 90%. It also saves you from the painful process of repairing or changing the inner tube in case of a puncture. Difficult to install if you don't have the right tools and if you haven't heated it up first to make it more flexible. Without anyone else's help, I finally managed to install it after quite some time and with the help of three wrenches and after 10 minutes of heating in hot water. Finally, for a Chinese product, the price could be much lower.

it is a very hard tire because it is solid so you put it by choice
For installation you will need 2 to 3 screwdrivers or two special levers and plenty of Ava (soap) and some zip ties and it goes on relatively easily, there is a relevant video

Hard rubber with good grip. It loses elasticity, so the potholes are a bit more jarring, but it is very durable.

The tire is fine, definitely harder than the one with the umbrella but much more durable. Basically, it's incomprehensible!! Now, as for the installation, it is a bit difficult but anyone can do it on their own... I needed three screwdrivers... Just use your knee or one leg, no need for cyclists or special craftsmen... Do it yourself, it's easy.

The first impression is quite good.. Definitely harder than the corresponding ones with an interior. It will show over time how durable they are.
Now, as for the installation, I found it easier than the regular ones with an interior. However, it requires 2 people for the installation. I soaked them in hot water for about 15-20 minutes. Then, I placed it on one side of the rim, holding and pressing with both hands while the second person used 2 screwdrivers to place them under the tire and pull against the rim. I also used a little WD40 and they went in perfectly. Minus 1 star for the long delivery time (20 days for Cyprus)... if possible.
