How often do you need 2 spare wheels?
I didn't notice that yesterday's strong winds had blown a paling off my old fence, and I drove over it, spiking two tyres on the car. Fortunately I noticed the effect of the deflation before heading out onto the freeway this morning, and returned home. One with a large screw embedded through the tread is pretty worn and would have to be replaced soon anyway, so that's not too bad, and I've fitted the spare wheel in its place. I then noticed the other on the same side was slowly deflating. I'll have to pump it up in the morning and go straight to the tyre shop. Hope it can be repaired, as I can't find anything external protruding.
