Ok actually a garage thought but anyway;
Got home from work on a wet night, car in the garage, fire on, dinner on, telly on, all is well.
Later in the evening I need some wood so its out to the garage where where I have a couple of days supply to save venturing into the outside wood box at night. It’s perfectly silent (no howling winds, no rain pounding on the steel roof, no hail!) and I heard a very faint burbling noise coming from somewhere near the car.
Maybe I left the radio on (it runs with ignition off but is supposed to turn off after 30 minutes) or something else still running, maybe fluid leaking from the cooling system or engine, air conditioner gas?
It’s not coming from the interior or engine bay, but nearer the rear of the vehicle. By the back tyre there’s a small puddle of rain water, not much larger than the contact patch, which had dripped off the tyre and it was shimmering. I roll the car back a few centimetres to find a nail stuck firmly through a tread block. The noise was air escaping, being compressed by the tread block and bubbling up through the puddle!
What the odds of the nail ending up in right place to be in the puddle when the car stopped, let alone me being in the garage when it was quiet enough to hear the bubbles!
I didn’t avoid a tyre change and trip to the repair shop tomorrow but meant could do it in the relative comfort of the garage and not in the morning rush!
