YeYouC 12.5x2.75 Replacement Knobby Tire & Inner Tube Set, 2-Pack for Razor MX350/MX400 — Butyl Tube, Wear-Resistant Tread

YeYouC 12.5x2.75 replacement tire and inner tube set is a two-tire kit (with tubes and valve caps) designed to restore traction and ride quality on scooters and small bikes that use 12.5 x 2.75 (62-203) inflatable tires.

If your Razor Dirt Rocket, Pocket Mod, X-Treme X-560 or compatible mini bike has worn, cracked, or flat tires, this kit supplies two outer tires and two matched butyl inner tubes sized to fit 12 1/2 x 2.75 wheels. The set is built from isobutylene isoprene rubber for the tire and thick butyl for the tube, pairing wear resistance and reliable air retention so you can get back on the road without buying a single replacement at a time.

Will these tires fit my scooter or mini bike?

These parts are designed to fit wheels labeled 12.5 x 2.75 (also listed as 12 1/2 x 2 3/4 and 62-203). Confirm the tire size printed on your old tire or in the vehicle manual before ordering. Many Razor Dirt Rocket models and a variety of Chinese-brand scooters and pocket bikes use this size.

• Outer diameter: 12.5 inches; tread width: 2.75 inches.
• Inner tube inflation range matches 12/12.5 x 2.5–3.0 widths for flexibility.
• Compatible references: Razor MX350, MX400, Pocket Mod series, X-Treme X-560, IMR, TaoTao, Apollo, Lifan.
• Always double-check the stamped tire size before purchase.

How do these tires and tubes improve ride feel and durability?

The YeYouC outer tire is made from isobutylene isoprene rubber, chosen for stronger wear resistance and better ageing characteristics than natural rubber. The matched inner tube uses thick butyl rubber and a bent CR202 valve stem for secure sealing and puncture resistance, together improving vibration dampening and air retention.

• Tread compound resists abrasion for longer service life.
• Thick butyl tubes absorb shocks and reduce flats.
• Angled CR202 valve stems offer easier inflation and reliable sealing.
• Improved elastic damping helps smooth rough surfaces.

What’s included and how do I install the set?

The package contains two 12.5x2.75 tires, two matching inner tubes and two valve caps. Installation follows standard tire-and-tube replacement: remove the wheel, deflate and remove the old tire and tube, mount the new tire, insert the tube partially inflated, seat the bead, then inflate to the recommended pressure.

• Contents: 2 tires + 2 butyl tubes + 2 valve caps.
• Use basic tire levers and a pump with compatible valve adapter.
• Inflate tube to fit 12 or 12.5 inch diameter as needed; adjust width to 2.5–3.0 inches.
• Check bead seating and tire pressure before riding.

Are there safety or compatibility notes I should know?

These tires are heavy-duty replacements, not OEM-specific branded originals; they suit many makes and models but are intended as fit-by-size replacements. Avoid modifying the tire or tube, and inspect rims and brakes for clearance before final installation. If in doubt, consult a technician.

• Compatibility is size-based—verify the old tire's stamped size.
• Not a direct performance upgrade claim—intended as replacement parts.
• Inspect rims, axles, and brake clearance before use.
• Contact YeYouC support for questions about fitment.
