Tuttio ARC-I Kids Dirt Bike Fat Tire Tuttio ARC-I Kids Dirt Bike Fat Tire, sized 16×3.0 inches, features an upgraded wider design compared to the previous 2.4-inch version, offering stronger grip and improved balance for a smoother ride. Important Note: If your original tire is 2.4 inches, the 3.0-inch model requires both the matching inner tube and outer tire to be replaced together. Please make sure to purchase the complete 3.0-inch set if upgrading, as buying only the outer or inner tire individually may result in installation incompatibility. Please note that accessories require a short preparation period before shipment. The standard delivery time for accessories is approximately 9–12 days. For accessories, returns or exchanges are only accepted in the case of confirmed quality issues. We are unable to accept returns for reasons such as personal preference or incorrect purchase.
