Review on Xiaomi Mijia M365 Electric Scooter Solid Tire Replacement - 8.5 Inch, Front/Rear - Set of 2 (Black) by Jason Sergeantson

As mentioned in other reviews, the tire itself is difficult to fit. However, if you have long, strong screwdrivers, they will harden as soon as you heat them to make them more flexible. It didn't impress me. I ride scooters every day. The same route every day. As soon as I mounted them on my scooter, I noticed that the acceleration dropped drastically. The hills that I used to be able to climb easily actually had to get off the scooter and walk. These tires create a lot of drag. My engine got warm, the mileage dropped by almost 6 km! I decided to switch back to an air-filled one and immediately regained my speed and mileage. When I installed them the scooter had so much drag that I could never move with it. Filled with air I can accelerate and ease off the gas and I drive quite a long time before I have to accelerate again. You'll never let off the gas or you'll quit almost immediately. I only weigh 170 pounds and noticed that the solid tires dropped a lot and the bumps were harder when I mounted them. I had less traction in the back as I almost slipped on very little gravel. This review has been written by a mechanical engineer for 25 years. Also remember that after a horrible installation process I took them off after 2 days to replace with air filled ones. Better to repair punctures now and again than to go uphill, lose speed, stress the engine and eventually lose distance compared to those hard tires.
