FVRITO 12.5x2.75 Knobby Tire & Inner Tube Kit for Razor MX350/MX400 — 2-Pack Reinforced, Puncture-Resistant

If your mini dirt bike, pocket bike or electric scooter uses a 12.5 x 2.75 (also sold as 12 1/2 x 2 3/4) tire, this complete kit supplies two heavy-duty knobby tires plus two inner tubes and the small hardware you need for an immediate swap. Built from reinforced rubber with a raised knobby tread, the tires are made to handle loose surfaces, light trails and everyday commuting while resisting common punctures. The package also includes valve caps, extra valve cores and a valve core wrench so you can service or replace components on the spot.

Will these tires fit my Razor MX350 or MX400 and similar models?

Yes — the FVRITO 12.5x2.75 set is sized specifically for Razor MX350, MX400 and a range of comparable mini bikes and scooters that accept a 12.5 x 2.75 wheel. Because manufacturers sometimes label sizes slightly differently, check the stamped numbers on your current tire or the vehicle manual before ordering.

• Compatible with Razor MX350, MX400, ZR350 and SX350 Dirt Rocket models.
• Also fits many X-Treme, eZip, GT, IZIP, Mongoose and similar scooters and e-bikes listed in the fitment details.
• Marked interchangeably as 12.5x2.75, 12 1/2 x 2.75 or 12 1/2 x 2 3/4.
• Confirm rim width and existing tire size to ensure a snug fit.

How does the knobby tread affect traction and ride comfort?

The raised block-style knobby tread improves grip on dirt, grass and gravel while the robust rubber compound absorbs small bumps to make short off-road runs more comfortable. These tires are not a high-speed racing compound but are tuned for durable everyday use and better control at low to moderate speeds on uneven surfaces.

• Knobby blocks increase bite on loose surfaces and soft ground.
• Reinforced rubber improves shock absorption on rough terrain.
• Engineered to reduce common punctures compared with thin, street-only tires.

What’s included in the kit and what tools or extras will I need?

The kit arrives ready to swap: two tires, two inner tubes and a set of small service parts so you can mount and secure the valves. You may still want basic tire irons and a pump or compressor to seat the beads and inflate to the correct pressure.

• 2 x 12 1/2 x 2.75 knobby tires and 2 x matching inner tubes.
• 2 red and 2 black stem valve caps, 2 brass valve cores and one valve core wrench.
• Recommended extras: tire levers, soapy water for bead seating, and a pressure gauge or pump.

How durable are these tires and how should I maintain them?

Constructed from heavy-duty rubber, FVRITO tires are built for stable structure and puncture resistance under typical mini bike and scooter use. Regular inspection for embedded debris, correct inflation and occasional rotation between sides will extend life and preserve consistent handling.

• Inspect for glass, nails or sharp stones after off-road rides.
• Maintain recommended tire pressure for load and terrain to prevent premature wear.
• Replace inner tube if punctured; spare cores and caps in kit simplify roadside fixes.

Who is this for: This FVRITO tire and inner tube set suits owners of Razor MX350/MX400 and other small dirt bikes, pocket bikes, electric scooters and mini motocross units using a 12.5x2.75 tire. It’s aimed at riders who want a cost-effective, ready-to-install replacement that improves off-pavement grip and offers tools and hardware for quick maintenance, without requiring professional installation for routine swaps.
