FVRITO 12.5x2.75 Knobby Tire & Inner Tube Kit — 2-Pack for Razor MX350/MX400, Heavy-Duty Off-Road Traction

FVRITO's 12.5x2.75 knobby tire and inner tube kit is a complete replacement set built for small electric scooters, pocket dirt bikes and 47–49cc mini motorcycles that need dependable traction and easy installation.

This kit pairs two heavy-duty knobby tires with matching inner tubes, valve cores and caps, and a small valve-core wrench so you receive everything required to swap worn tires in one purchase. The tread profile and rubber compound are engineered for mixed off-road and pavement use, giving better bite in loose dirt while still rolling smoothly on sidewalks or driveways. Fitment covers many popular models including Razor MX350/MX400 Dirt Rocket, X-Treme X-560, and a wide range of 12.5x2.75 applications across e-scooters, pocket bikes and mini pit bikes.

Will these tires fit my Razor MX350 or MX400?

Yes—these tires are made to the 12.5x2.75 specification commonly used on Razor MX350 and MX400 models. Confirm your existing tire sidewall reads 12.5 x 2.75 (or equivalent markings) before ordering to ensure correct fit. The kit includes valve cores and caps compatible with straight valve stems frequently found on these scooters.

• Exact size: 12.5 x 2.75 (also labeled 12 1/2 x 2 3/4)
• Compatible models listed: Razor MX350, MX400 and similar scooters
• Includes straight valve-compatible cores, caps and wrench

How durable are the tires for everyday use?

The tires are constructed from a heavier rubber compound designed for puncture resistance and improved shock absorption, making them suitable for daily commuting and light off-road riding. The reinforced casing and knobby tread pattern help protect the tube and maintain stability under common riding stresses.

• Heavy-duty rubber for longer wear and tear resistance
• Knobby tread for traction on loose surfaces and dirt
• Sturdy structure to reduce pinch flats and maintain handling

What exactly comes in the package and how easy is installation?

The kit ships with two tires, two inner tubes, two red and two black valve caps, two brass valve cores and a valve core wrench — everything to replace both wheels. Installation is straightforward for anyone comfortable changing small scooter tires; basic tire levers and a pump are all that’s additionally required.

• 2 x 12.5x2.75 tires and 2 x matching inner tubes
• 2 red and 2 black valve caps, 2 brass valve cores, valve core wrench
• Simple DIY swap: remove wheel, replace tire and tube, reinstall and inflate

Can these tires be used on gas-powered 47cc–49cc mini bikes?

The 12.5x2.75 size fits many small gas and electric mini bikes that specify the same tire dimensions, so they are often suitable for 47cc–49cc pocket dirt bikes and pit bikes. Always verify hub width and axle fitment on your bike before purchase to ensure proper clearance and safe mounting.

• Works with many 47cc–49cc mini bikes using 12.5x2.75 tires
• Check axle diameter and hub spacing before installation
• Ideal for mixed pavement and light trail use on small bikes

It’s designed for people who want improved grip and reliability over worn stock tires, and for DIYers who prefer a plug-and-play solution that includes the valve parts needed to finish the job without extra purchases.
