Concise Title: 2-Pack 4.10/3.50-4 Inner Tubes, TR87 Valve Stem for Hand Trucks, Wheelbarrows, Mowers and More

We have over 20 years of experience in the tyre industry, making us experts in this field and enabling us to recommend the best products for you. When your wheel leaks, you do not have to discard it entirely. By simply replacing the inner tube with one of the same size, you can breathe new life into the wheel, saving you money and being environmentally responsible.

Our 4.10/3.50-4 inner tube is crafted from high-quality natural rubber. Compared to the common natural rubber wheelbarrow inner tubes available on the market, the formula used for our motorcycle inner tube contains a much higher percentage of real natural rubber, making it the pinnacle in its class.

The distinguishing features of our natural inner tube include: • Excellent air retention capabilities, with a rate over 6 times that of natural rubber; • Improved tyre tread life and reduced rolling resistance; • Superior tear resistance, heat resistance, weather resistance, and anti-oxidation properties, as well as excellent environmental resilience.

This 2-pack of replaceable 4.10/3.50-4 inner tubes is compatible with 4" rims and 3.00", 3.50", 4.00", and 4.10" tyre widths, as well as 10" or 11" outside diameter tyres and wheels. They are also known by the alternative names 410/350-4, 4.10 3.50-4, 410-4, 350-4, 400-4, 410 350-4, 410 350, 4, 410 x350-4, 4.10x3.50-4, 4.1-4, 3.00-4, 300-4, and 3.00x4. Please ensure the size matches your requirements before placing an order.

These inner tubes are versatile and can be used with a wide range of equipment, including hand trucks, wheelbarrows, garden and utility carts, lawn mowers, small tractors, yard trailers, dollies, trolleys, wagons, flat carts, generators, snow blowers, pressure washers, air compressors, and wood chippers, among others. Additionally, a leaked tubeless tyre can be repaired by fitting one of our inner tubes.

Each inner tube is marked with a blue line on the body and features a TR87 curved nozzle valve for easy inflation. The high-standard formula, high rubber content, and superior aging resistance, high-temperature resistance, ductility, and strength of these inner tubes result in a longer service life and 6 times better air retention compared to regular rubber inner tubes, providing you with a better user experience.

Included in the complementary accessories package are 1 valve spanner, 3 valve cores, and 2 valve nozzle caps, making it convenient for you to deflate, replace, and maintain the inner tube and valve core.

We offer a 24-hour after-sales service hotline and a 30-day free return and exchange policy for any quality-related issues, ensuring your peace of mind. If you have any questions, please do not hesitate to contact us.
