Many years ago (must be about 15) I bought a heavy duty wheelbarrow tyre, at what I thought was an extravagant price at the time, to try and mitigate the attentions of the Rotti. It worked well and she did not puncture it and the heavy thread on it stops the normal hawthorn punctures. The problem now is not the tyre, which looks as good as new, but the wheel barrow itself is now nearly worn out: The tube around the front of the tyre is worn more than 1/2 way through, one handle is 4" higher than the other and the whole thing flexes alarmingly when full.
I have two other wheel barrows with the normal tyres and have at least two spare redundant wheels off old barrows, all tyres are perished and need replacing. I am still not sure how I have managed to collect so many barrows. As with tools I have to keep telling myself I am a user not a collector
I think I will stick with pneumatic tyres, I was hoping that the solid ones may have improved since I last used one.
