I find people's attitudes to tyres quite intriguing.
A reasonable car might cost something like £1500/yr in depreciation, insurance, MOT/tax, servicing etc, plus 10-15p/mile in fuel so another £500-1000 ballpark, north of a couple of grand a year total typically.
The tyres are what take you directly to the scene of the accident.
I'm not sure why maybe £300 for a set of decent tyres for a common size known brand every 5yrs or something seems so outrageous to some folk.
Each to their own of course, I'm somewhat obsessive about tyres I freely admit, I've changed car tyres which are only slightly worn but are getting near 10yrs old (summer toy car), and only 5yrs old on a motorbike.
Anyone (well, most anyway) who rides motorbikes will know the difference between really good tyres and not-so-good can be dramatic, alarming, and indeed scary.
A comment in that video about the "British" attitudes is true. A friend worked for a company making wiper blades (among other things), Britain had by far the lowest sales of wiper blades per registered vehicle of any European country, presumably because we are just tight wads. We don't change wiper blades until the metal is scoring the screen and the rubber is dangling in the breeze. Predictably Germany has the highest sales.
