CMOOD 12.5 x 2.25 Tire & Tube Set — Pair for Razor Pocket Mod and Mini Dirt Bikes, TR13 Valve Butyl Tube

CMOOD 12 1/2 x 2 1/4 Tire and Tube Set is a ready-to-install replacement tire and inner tube crafted for 12.5 x 2.25 wheels on pocket bikes, mini dirt bikes, scooters and many kids' e-bikes.

This pair (tire + TR13 straight-valve tube) fits many popular models from Razor, Currie, Schwinn, GT, IZIP/eZip and other small-wheel bikes and scooters that use the 57-203 / 62-203 sizing. The tire uses a durable isobutylene-isoprene rubber compound for better air retention and aging resistance, while the tread pattern and thickness are tuned for traction and smoother ride on sidewalks, driveways and light off-road surfaces. These are aftermarket replacements designed to restore rideability when your original tires are worn or punctured.

Which vehicles is this 12.5 x 2.25 set compatible with?

This tire and tube set is intended for scooters, kids' dirt bikes, mini crosser vehicles and balance bikes with 12.5-inch by 2.25-inch wheels. It lists compatibility with many Razor Pocket Mod models (Bella, Betty, Vapor, etc.), Razor Dirt Rocket series, and other small electric scooter and mini bike brands.

• Fits 12.5 x 2.25 (57-203 / 62-203) wheel applications.
• Commonly used on Razor Pocket Mod and Dirt Rocket MX models.
• Works with various Currie, Schwinn, GT, IZIP, eZip and X-Treme mini bikes/scooters.
• Also suitable for many kids' balance bikes and mini e-bikes that accept this size.

How does the material and construction affect ride quality?

The tube is made from butyl rubber (isobutylene-isoprene) for improved air retention and better resistance to aging compared with natural rubber tubes. The tire compound and shallow-siped tread are designed to absorb small bumps and provide consistent traction on pavement and packed dirt.

• Butyl inner tube for high air tightness and lower inflation loss.
• Shallow sipes and even tread wear for predictable handling.
• Thicker rubber provides shock damping for smoother rides.
• Improved aging resistance for longer service life in outdoor use.

What should I check before buying and installing this replacement set?

Confirm your wheel diameter and rim width match the 12.5 x 2.25 specification and verify valve type (TR13 straight valve) fits your rim. Inspect the inner tube in water before installation; bubbles indicate damage and you should request an exchange if found.

• Verify wheel spec: 12.5" x 2.25" (57-203/62-203).
• Confirm TR13 straight valve compatibility with your rim valve hole.
• Test new tube in water for leaks prior to fitting.
• Remember these are aftermarket replacements, not OEM parts.

How do I get support if the tire or tube has a problem?

CMOOD provides email support for fitment questions and returns. If the inner tube leaks during the pre-installation water test or the item arrives damaged, contact the seller promptly to arrange exchange or refund.

• Contact vendor by email for any defects or fit issues.
• Report leaks found during the water-seal test for a quick resolution.
• Keep order details and product photos to speed support.
