Had my 4th tyre puncture in over 50 years of driving today and goodness how many miles. I think my latest Corsa is jinxed. At least the TPM warned me and so I went home straight away. I'd replaced the tyre repair kit with a spare wheel (185 70 x14) and tool kit on my Corsa D and swapped them over. My friend did the same on his earlier Corsa E. Same size wheels (195 55 x16) and same size spare. His spare fits and mine doesn't. It won't clear the caliper. So what size spare am I supposed to have? Also, I inpected the punctured tyre and could find no nails, scews or damage.
