【Heavy-Duty Premium Rubber】Crafted from thick, high-grade natural rubber for superior durability, elasticity, and puncture resistance. These tire tubes offer longer service life, better heat resistance, and improved aging protection compared to ordinary rubber inner tubes.
【High Air Tightness & TR13 Straight Valve】Equipped with a TR13 straight valve stem for easier inflation and a more secure seal, making it ideal for tight rim spaces or low-profile wheels.
【Quick & Easy Installation】Simply deflate the old tube, remove it, insert the new one, inflate using a manual air pump (30 PSI maximum inflation), and you're back in action. Only inflate with manual pump to avoid overfilling. Not for road/highway use.
【Wide Compatibility】Fits most 4.00-8” tires with 8" rims and 15.5" outer diameter. Ideal replacement inner tubes for wheelbarrows, lawn mowers, garden/utility carts, hand trucks, yard trailers, wagons, snow blowers, air compressors, generators, go-karts, and more.
【Cost-Effective 2-Pack】Includes 2 high-performance 4.80/4.00-8 inner tubes, giving you a spare for future use or for dual-wheel applications. A smart and affordable choice for home and professional users. Please check your tire size before purchasing.
