Review on 🔧 Set of 2 High-Strength Inner Tubes (4.80/4.00-8") for Minibike, Go Kart, Mower, Hand Truck, Wheelbarrow, Cart - Durable Rubber Replacement Tubes by Craig Mcdonald

I bought them for a towed garden cart. Installed easily as expected. I have made several of these tires and have a set of tire changers and a small HF tire changer to make things easier. **Must apply a small amount of lube to the tire bead.** Soapy water works great. It's also important to check the inside of the rim for problems. I found a small sharp piece of metal - probably from the original rim manufacturer - that probably caused the previous tube to fail. The offending spike was removed in a matter of seconds with a grinder/file, but carefully inspect the rim and inside of the tire for sharp objects before installation. And be careful not to jam the new tube with crappy old screwdrivers when installing it. It appears to be a high quality hose with brass valves. Holds full pressure for almost a month with heavy use so far. Good deal for this price for two.
