I know there is never a good time to get a puncture, but while in the supermarket is pretty bad timing. I noticed the rear left tyre was low as we got back to the car to load the shopping in, but I figured that I'd put some air in at the petrol station next to the supermarket, enough to get me home and then change the tyre for the spare.

So we loaded the shopping in and drove about 100 yards to the airline and waited for the car using it to finish. When I looked at the tyre it was totally flat...that's not a good sign. Being an optimist, I put the airline on it anyway, but the sound of air hissing out and the fact it wouldn't hold any pressure let me know it was in vain.

We parked back in the car park and unloaded the shopping back into a trolley so that I could get the jack and spare wheel out of the car. Luckily, the weather was dry, the bolts came out easily and the wheel wasn't stuck to the hub. The kids got to see first hand how to change a wheel, I'm so glad it went well and I didn't get stressed. So in about 10 minutes, the wheel was changed, the shopping packed back in and we were on our way home. You never want a puncture, but if you have to have one then a straightforward on is the type to have.
