Hey Razor scooter owners! If you're dealing with a flat tire or worn-out rubber on your Pocket Mod, this Wingsmoto tire and tube set is exactly what you need to get rolling again. This isn't some generic replacement - it's specifically designed for the Razor Kid Electric Scooter Pocket Mod and other 12-inch electric wheelchairs with 8-inch rims (rim diameter about 220-225mm). The package includes both the tire AND inner tube, so you get everything you need in one shot. The tire size is 12 1/2 x 2 1/4 with an outer diameter of about 11.8 inches when not inflated. The inner tube features a TR13 straight stem - super important to check that this matches your scooter before ordering! What's cool about this tube is it's made from isobutylene isoprene rubber, which actually has better air tightness, elastic damping, and aging resistance compared to natural rubber. Maximum inflation is 40 PSI (280 KPa), giving you that perfect firm ride. Installation is straightforward if you're handy, or any bike shop can knock it out quickly. Seriously, if your scooter's been sitting unused because of tire issues, this affordable replacement set will have you back in action in no time. Perfect for parents dealing with kids' scooter maintenance or anyone who relies on their electric scooter for getting around.
