2 Sets 18x2.125 Bike Tire and Tube with 2 Levers

Application: This 18x2.125 bike tire set, also known as a 54-355 tire and tube set, is a replacement for Royalbaby BMX bike, Joystar balance bike, road bicycle, folding bike, and more.

Tire: Constructed from high nylon content rubber, the 18 inch bike tire offers greater heat, puncture, and abrasion resistance compared to traditional all-rubber tire materials. The collapsible design allows for easy storage and transport of spare tires.

Tube: The 18x2.125 inner tube is made from thickened butyl rubber, providing longer air retention and enhanced stretching and shock absorption for a smoother ride.

Valve: Featuring a pure copper valve with rubber wrapping for increased resistance to oxidation and rust, the 18" bike inner tube maintains air tightness and resistance to bending for long-lasting air pressure.

Features: The surface of the 18 inch bicycle tire is equipped with a symmetrical directional tread pattern for strong grip on the road, while secret drainage grooves on both sides ensure handling performance on wet roads. The pure copper straight air nozzle is corrosion-resistant and prevents air leakage without occupying lateral space.

Package includes: 18 x 2.125 outer tire x2, 18 x 2.125 tube x2 (with pure copper straight valve), Lever x2.
