This is the thirteenth puncture and seventh tyre I've had to replace since working where I do now. All from self tapping screws picked up from various company car parks and yards. 7 tyres in 24 years, spread over seven cars...two on my current Supra in 5 years.
Unfortunately, yet again, I didnt notice the puncture until I'd driven far enough to trash the sidewall. Only takes a mile or so to powder it up Otherwise, yet again, it could have been repaired I think.
I think I've posted before that when I complained about this a while back I was told I was lucky not to get done for taking company property (the screw) off-site without a chit. He laughed, I didn't.
