The 3.00-4 straight valve TR13 MOOVMOOV inner tubes are a popular variant for small vehicles such as lawnmowers, hand trucks, wheelbarrows, carts, and garden trailers. The TR87 angled valve allows easy access for inflating the inner tube, even in limited spaces, and is commonly used in agricultural and industrial applications. These inner tubes are made from high-quality materials, including natural rubber, to provide increased puncture resistance and durability. Additionally, they offer improved shock absorption due to their thickness, ensuring a more comfortable ride for the user.
