YeYouC 12.5x2.75 Replacement Tire & Inner Tube Set — 2-Pack for Razor MX350/MX400, Heavy-Duty Butyl Tubes

YeYouC 12.5x2.75 replacement tire and inner tube set provides two durable 12.5" x 2.75" tires and two matched butyl inner tubes designed to fit Razor MX350/MX400 and many 12 1/2 x 2.75 scooters and mini-bikes.

This replacement kit includes two heavy-duty tires and two thick butyl inner tubes with bent valve stems plus valve caps. The tires measure 12.5 inches in outer diameter and 2.75 inches in width (marked 62-203) and are paired with inner tubes that can be inflated to match 12 or 12.5-inch diameters and widths from 2.5–3.0 inches. Constructed from isobutylene isoprene rubber and reinforced butyl tube material, the components are built for wear resistance, improved air retention and reliable ride cushioning on small electric and gas scooters, pocket bikes, and similar ride-ons.

Will these tires fit my Razor MX350, MX400 or Pocket Mod scooter?

These tires are intended as direct replacements where the original tire size is 12 1/2 x 2.75 (12.5 x 2.75 / 62-203). They are commonly compatible with Razor Dirt Rocket MX350 and MX400, multiple Pocket Mod models, and a range of Chinese-brand scooters and mini bikes. Always measure the existing tire dimensions before purchasing to confirm fit.

• Outer diameter: 12.5 inches; width: 2.75 inches (marked 62-203)
• Inner tube inflates to 12 or 12.5 in diameter; widths: 2.5, 2.75 or 3.0 in
• Commonly compatible with Razor MX350, MX400 and many Pocket Mod variants
• Also fits several IMR, TaoTao, Apollo, Lifan and other Chinese scooters with same size

How do the materials and construction affect ride quality?

The outer tire is made from isobutylene isoprene rubber for enhanced wear resistance and better anti-skid performance compared to standard natural rubber. The matched inner tubes are heavy-duty butyl rubber, offering improved airtightness and vibration damping, which helps smooth bumps and maintain pressure for longer rides between inflations.

• Isobutylene isoprene rubber for wear resistance and traction
• Thick butyl inner tube for air retention and shock absorption
• CR202 bent angled valve stem for secure sealing and easy inflation
• Two valve caps included to protect stems from dirt

What’s included in the package and how easy is installation?

The kit ships with two tires, two matched inner tubes and two valve caps — enough to replace both wheels on many scooters. Installation follows standard small-wheel tire mounting: remove the old tire and tube, seat the new tube inside the tire, fit the assembly on the rim, then inflate to the chosen diameter and width. If you’re not experienced with tire mounting, a local bike shop or scooter repair shop can complete the swap quickly.

• Contents: 2 x 12.5x2.75 tires, 2 x matched inner tubes, 2 x valve caps
• Inner tube stem type: CR202 bent/angled stem for accessibility
• Inflation flexibility: choose 12" or 12.5" diameter; width to 2.5–3.0"
• Simple tools required: tire levers, rim protectors, pump with proper valve head

How durable are these tires for everyday scooter use?

These tires and tubes are designed for regular urban and off-road light-duty use on small scooters and mini-bikes. The compound and tube thickness prioritize puncture resistance, wear life and consistent air retention. Routine inspection and correct inflation pressure will extend lifespan and preserve the intended ride characteristics.

• Reinforced rubber compounds for longer tread life
• Thick butyl tube for puncture resistance and vibration reduction
• Compatibility with light off-road and pavement riding on small scooters
• Recommended to confirm size prior to fitting for best longevity

Who is this for: This YeYouC 12.5x2.75 tire and tube set is aimed at owners of small electric or gas scooters, pocket bikes and child ride-ons that require 12 1/2 x 2.75 tires — especially Razor Dirt Rocket MX350/MX400 and Pocket Mod series owners. It’s also a practical replacement option for hobbyists, repair shops and anyone looking to restore wheel performance with a budget-friendly, heavy-duty tire-and-tube combo. Verify your current tire size before ordering to ensure compatibility.
