I've been folding tyres, well, that's what they're for. It even says it on the packaging 'folding tyre'. So I've been folding them, about 27 or 28 of them in a therapeutic sort of way - well, more rolling them up, then sticking a ring of chopped-off downhill tube around them. It was the only way to stop them getting out and taking over the kitchen in a sort of anarchic rubbery invasion.
Worryingly I seem to have more tyres than, say, for the sake of argument, socks, which can't be right, can it? Still, it stops you thinking.
