Inner Tube 4.8/4.00-8 for Wheelbarrow Tire 8

The Potreba Inner Tube 4.8/4.00-8 is designed specifically for wheelbarrow tires with an 8" rim. It is suitable for the 4.80/4.00-8 wheel size, which has a 15.5-inch outside diameter tire. The inner tube comes with a straight valve TR13 that can be easily pumped up with a standard car pump. Made with strong rubber containing 30% natural rubber content, this inner tube is durable and reliable.

It is important to note that this inner tube is not suitable for highway use and is intended specifically for wheelbarrow use. The maximum load on the inner tube within the wheel is 260 lb at 30 PSI maximum inflation.

For those looking to replace the inner tube in their wheelbarrow, there are a few important steps to follow. Before installation, it is crucial to check for air leaks by creating a small pressure in the inner tube and placing it in water to detect any leaks.

To begin the replacement process, the wheelbarrow should be turned over to access the wheel. The bolts holding the axle should be removed, allowing the wheel to be taken off the axle and laid on a sturdy work surface with the valve pointed skywards.

Using a tyre lever or a large flat screwdriver, carefully break the bead between the tire and the rim. Then, flip the ridge of the tire over the rim's edge all the way around. At this point, the tire is only partially fitted to the rim, allowing for the valve head to be pushed back into the rim and the old tube to be removed.

The new tube can then be laid over the wheel, ensuring that the valve is positioned the same way with the valve head pointed outwards. After inserting the tube into the tire and over the rim, the valve stem should be carefully aligned through the hole in the rim. It is important to check that the tube is not twisted before refitting the tire to the rim and filling it with air.

To alleviate any bunching, twists, or tensions between the tube, tire, and rim, the wheel should be spun and tapped with a rubber mallet. Finally, the wheel should be filled up to a maximum of 29psi until the tire bead expands against the rim.

In conclusion, the Potreba Inner Tube 4.8/4.00-8 is a reliable and durable option for wheelbarrow tires with an 8" rim. With the proper installation process, it can provide long-lasting performance for wheelbarrow use.
