Went out to the car this morning and noticed one of the rear tyres was flat. Yes, that'd be one of the rear tyres that just cost me £150 each and haven't done 1000 miles yet.
Removed tyre and fitted spare, breathing a huge sigh of relief to note a nice neat repairable nail hole near the centre of the tread, so hot-footed it round to tyre specialists (ok luke-warm-footed on space saver).
Oh dear. When tyre was removed inside was a cup full of tell-tale granules of rubber, indicating that the tyre had clearly been driven flat and was now therefore scrap.
My problem (apart from the £150 bill) is that I'm at a loss to know how to avoid this in future. The last journey I did in the car was about 5 miles at relatively low speeds, ie < 50mph, though involving a fair bit of cornering, but I can recall no symptoms whatsoever of the tyre being flat.
I'm aware this makes me appear a bit of a numb-skull, but the problem is that with low profile tyres there is hardly any sidewall there to start with, and necessarily it is mega stiff, so the tyre still provides a good deal of lateral support when flat.
