So I had a good lesson yesterday. Flat tyre literally in the middle of nowhere in Kalahari desert at 2pm! I had to get a towel to put on the ground to make sure didn't touch it as it was so hot. I had instinct reaction and took jack out and started jacking the car up. Fortunately didn't waste the effort of dropping the spare tyre before realising mistake. Jacked down the car, got compressor out, inflated tyre and poured water over it. I identified the puncture and it was quite small. Moved the car to have puncture more accessible and got the tyre repair kit out. Fixed in 5 minutes, fully reflated and got on my way.

Highly recommend having both a compressor and repair kit in vehicle if heading into isolated areas but also, stop and think. Due to heat and going slow, whole thing took half an hour but could've been a quick 5 minute job. Good lesson for me!
