The original built-pneumatic tire of the hand truck were already when new flat and had to first be inflated, after a short time stopped one of the wheels, the air only 5 minutes at some point it was no longer there and you could forget about the hand truck. Here I then came across this solid rubber wheels whose rims are also ausgestettet with ball bearings, which ensures a better run when loaded. Clear recommendation, because here is saved with most cheap handcarts, the frame itself is good, the wheels can be forgotten. So these wheels on here and the handcarts is a reliable helper.
