A while ago I thought, 'I must get a spare trolley tyre as a backup,' in case of punctures. But did I? No! Course the inevitable happens yesterday. Whilst wheeling through some autumn leaves I didn't notice that one of my custies had trimmed a thorny hedge. With a full load of water a 'Freedom trolley' is about a 45 kilos. So you guessed it. Flat tyre and two and a half hours of a lovely day wasted running round trying to get it sorted and it could have been worse. They can be repared but this is very difficult and requires two people to accomplish getting the tyre back on. (If you ever have this problem, use soap on the rim it makes it easier) Be careful not to damage the inner tube. It's very easy to do.
My recomendation - Get a spare tyre! It will save you wasted time
