About this item

• Application: Tired of the same old black tires. This All White 18x2.125 kids bike tire sets also written as 57-355 tire and tube sets, replace for bmx bike, Joystar balance bike, road bicycle, Folding Bike and more.
• Wear-resistant and Shock-absorbing : This 18 inch kid bicycle 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. The tube made of thickened butyl rubber holds air in the inner tube longer, while the greater thickness allows for better stretching and shock absorption for a smoother riding experience
• Features: This 18-inch bicycle tire features an all-white design, making it ideal for pairing with the vibrant frames of children's bikes. Its symmetrical directional road tread pattern reduces pedaling effort, while the small tread blocks allow for denser drainage channels, enhancing traction. The foldable design ensures compact portability, making it an excellent choice for urban cycling.
• AV Copper Valve: This 18" 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.
• Package includes: 18 x 2.125 white outer tire x2; 18 x 2.125 tube x2 (with pure copper straight valve); 1x valve core wrench; 2x aluminum valve cover; 5x valve cores; 2x red pry bar
• Installation Tips: The tubes are secured with plastic zip ties. Using scissors, utility knives, or forcefully pulling on the cable ties may accidentally puncture or scratch the rubber layer of the inner tube, causing damage. Please handle with care. Before installation, pre-inflate the inner tubes and place them in water to check for air bubbles. When installing the outer tires, be careful with the tip of the tire lever to avoid puncturing the inner tubes.
