The biggest problem I have seen is LOW TIRE PRESSURE.. Most of these small tires easily run 50 to 90 pounds air pressure but most people only run them around 30-35..
Tires can and will spin on the rim at low pressures during landings.. Another way to stop pinching the tube is during mounting take a plastic bottle, like a milk bottle or bleach bottle, and cut a strip about 2 inches wide around the bottle. Place this inside the expanded tube before installing it on the split rim.. This will eliminate the possibility of pinching the tube when pushing the wheel halves together. Check the tire pressure regularly.. Keeping the pressure up also makes the tire run cooler. Ron
