finally got tired of replacing the cheap Chinese pneumatic 10"tires and wheels on both my light handtruck and pressure washer. Got online last week and bought a 4-pack of solid pneumatic tire/wheel combos for them both..never felt so good throwing the old leaking ones in the trash..every year having to disassemble and replace the tubes..what a drill that was. Hopefully this will solve THAT problem..on to the next one!
