About this item

  • Application: This 18x2.125 bike tire set is also written as 57-355 tire and tube set, replace for bmx bike, Joystar balance bike, road bicycle, Folding Bike and more.
  • Tire : This 18 inch bike tire is made from high nylon content rubber, which provides greater heat, puncture and abrasion resistance than traditional all-rubber tire materials that wear out faster. This 18” tire is also collapsible, which means you can easily carry a spare tire or store it.
  • Tube : We used thickened butyl rubber to create the 18x2.125 inner tube as a pairing, this rubber holds air in the inner tube longer, while the greater thickness allows for better stretching and shock absorption for a smoother riding experience
  • Valve: This 18" bike inner tube is made of pure copper valve with rubber wrapped around the stem surface to isolate water vapor and air, which is not easy to oxidize and rust, and increases air tightness and resistance to bending, and can maintain sufficient air pressure for a long time.
  • Features: The surface of the 18 inch bicycle tire uses symmetrical directional tread pattern, which can better contact the road surface to provide strong grip, and the secret drainage grooves on both sides can ensure the handling performance under the waterlogged road surface. The inner tire is made of pure copper straight air nozzle, which is corrosion-resistant and does not leak air without taking up lateral space.
  • Package includes: 18 x 2.125 outer tire x2; 18 x 2.125 tube x2 (with pure copper straight valve); Lever x2

Great replacement for my kid's bike tire, fit the 18x2.125 wheel as well as the original tire.Because the tire comes flat and folded over it took a bit to position it well, but it held it's shape well after a few minutes. Never seen a tire come packaged like this.Overall a great replacement. It comes with tubes and 2 plastic tire levers to help removing the old tire and putting on the new one.
