If you're riding a Gorax GXL V2 or Xiaomi M365 scooter (or any 8.5-inch electric scooter really), these replacement tires are exactly what you need when your current ones wear out. The set includes both the inner tube and outer tire - everything you need to get rolling again. The inner tube is made from butyl rubber which holds air way better than cheap alternatives and lasts longer too. The tread pattern is seriously grippy, giving you better control when turning and braking, which honestly makes riding so much safer. What's cool is that the design actually helps with battery life too - the shallow structure reduces rolling resistance so you can go further on a single charge. Installation is pretty straightforward if you've changed bike tires before, but just make sure you're getting the right size - these are specifically for 8.5-inch wheels with straight valve stems. They fit models like Gorax GXL V2, Xiaomi M365, M365 Pro, Pro2, 1S and other similar scooters. The air cushioning makes bumps and vibrations way more manageable, so your hands won't feel as numb after a long ride. Definitely a solid upgrade from stock tires that'll make your daily commute much more comfortable and reliable.
