We seem to be getting new ones as quickly as the old ones get filled up. It's only raining around here, we haven't had any real winter weather yet. I take between 3 and 5 thuds before I remember where each one is. Perhaps a broken wheel would improve my memory.
People get het up about pranging their tyres elsewhere too: in Saudi Arabia and London.
