HIAORS 12.5x2.75 Tire & Inner Tube Set for Razor MX350/MX400 — 12 1/2x2.75 Replacement, Durable Tread

HIAORS 12.5x2.75 tire and inner tube set replaces worn or damaged 12 1/2 x 2 3/4 wheels on Razor MX350/MX400, X-Treme X-560, EZIP 750/500 and compatible mini pocket bikes and gas/electric scooters.

This aftermarket replacement bundle includes one 12.5x2.75 outer tire and one matching inner tube engineered to fit a range of mini dirt bikes, pocket bikes and small scooters. The set is designed to restore traction, ride comfort and reliability when the original tire or tube has worn thin, split, or gone flat. Before ordering, confirm the wheel diameter and tire width on your vehicle to ensure correct fitment.

Will this tire and tube fit my Razor MX350 or MX400?

Yes — the HIAORS set is made to the 12 1/2 x 2 3/4 specification that matches many Razor MX350 and MX400 models as well as several X-Treme and EZIP mini bikes. Fit depends on rim width and mounting clearance, so measuring your current tire or rim first is recommended.

• Nominal size: 12.5 x 2.75 (12 1/2 x 2 3/4)
• Includes one outer tire and one inner tube
• Aftermarket replacement; check rim compatibility

How durable and safe is this replacement compared to originals?

The tire is produced as an aftermarket part to meet common mini-bike requirements — it restores tread depth and sidewall strength for everyday riding on pavement, driveways and light off-road trails. The paired inner tube is sized to reduce pinch flats when properly inflated, but like all tires it should be inspected regularly for cuts or embedded debris.

• Replaces worn tread and aging rubber
• Inner tube sized to match tire dimensions
• Suitable for typical recreational riding conditions

How do I install the HIAORS 12.5x2.75 tire and tube set?

Installation can be done with basic tire tools: wheel removal, bead seating, and tube inflation. If you’re unfamiliar with small-wheel tire changes, a bike shop or scooter technician can mount and balance the wheel quickly to ensure a proper seal and safe ride.

• Remove wheel from vehicle before mounting
• Use tire levers and light soapy water for bead seating
• Partially inflate tube before tucking it into the tire to avoid pinching

What should I check before buying this replacement set?

Confirm your current tire markings match 12 1/2 x 2 3/4 and verify rim size and valve type. Also check that the tread profile and overall diameter will clear forks, frames and brakes on your specific model to avoid fitment issues.

• Read tire sidewall for exact sizing information
• Compare rim width and valve stem orientation
• Measure clearance around forks and brake assemblies
