It may not seem like it at first, but inner tubes are vital for a smooth ride on your Xiaomi M365 scooter. For starters, pneumatic tires enable M365 to have minimal rolling friction and better traction, resulting in lesser power draw from the battery and better mileage. But since M365 does not have built-in shock absorbers, you\'ll need to depend on the inner tubes\' cushioning capabilities as the scooter\'s sole form of suspension. With thicker and more durable make, these inner tubes are more than capable of dampening vibrations and impacts from rough roads and obstacles. Xiaomi recommends that M365 be only used on asphalt, cement, and flat soil pavements. It\'s able to navigate bumps or steps that are less than 1 cm in height. With these inner tubes\' high tear resistance and self-sealing features, you can easily navigate these terrains without the fear of constant punctures and flats. With the inner tubes\' vibration dampening capabilities you can take your Xiaomi M365 on any road any time of the year. Several Razor scooter models that are compatible with these inner tube replacement pack include Razor E100 (Front), Razor E125 (Front), Razor E150 (Front and Rear), Razor E200 (Front and Rear), Razor E-Punk (Front), and Razor Dune Buggy (Front and Rear). These Razor models use 8 inches by 2 inches tires. There are several advantages to using a slightly bigger inner tube, one is that it reduces the chances of flats. The only downside is the possibility of pinching the inner tubes between the rim and tire so careful installation is necessary.
