This is a good thick rubber hose. I changed a tire on my farm cart; For reasons that are unclear, the new tubeless tire never fitted perfectly on the rim. I assume there is a small size difference between the supplied Chinese wheelbarrow tires and the boat trailer tires. In any case, the tire kept leaking between uses and putting it back on the rim was a pain. "Stop-Leak" was unsuccessful. After inserting a tube, it was permanently fixed. A few things if you're too young to remember tubulars: Don't use low-pressure tires; If the tire slips on the rim, it rips the valve out of the chamber. Put something on the valve during the installation and inflation process, otherwise it will slip back into the rim and you will have to do it all over again. Be very careful not to pinch the tube or valve while mounting the tire or you will have to patch it back up and do it all over again. Make sure the rim is clean and smooth, especially the welds; Rust or spatter enters the pipe. Fully inflate the tire to seat the bead, then deflate ALL the air to the last drop to deflate the tube and inflate again; Otherwise, the tube will be stretched thin wherever the tire moved when it touched down. The main reason an inner tube leaks immediately after installation is that your tire fitting tool pinched it in the tire and punctured it while installing the tire. Hold the end of the tool just above the edge of the rim without going into the tire. Tire changers have a soft hook at the end to make it easier to drive over the edge of the rim. Using screwdrivers is a pretty good way to damage the bead, tube and rim. When using motorcycle tires with spoke inner tubes, get motorcycle tire tools right here at Revain. Edit: It's been 2 years since no issues were reported; Use the trailer to transport firewood. I'm buying another one to fix a slow leak in my dung cart tire.
