As others have said, technically speaking, unless they have all just been replaced, all second hand cars are equipped with “part worn” tyres.
However, that does of course not mean that the car has ever been fitted with ”used” tyres.
Surely the term “part worn” with respect to tyres is only used as a marketing term to make the tyres perhaps sound like more of an attractive low-cost solution than they would be if they were more candidly referred to as what they really are, which is “used”. Second, third or even fourth hand. There’s now way of knowing.
Undoubtedly the market for part worn tyres is quite a lucrative one, where items are sold for good money, items that would otherwise be deemed scrap and in certain cases may not only have been previously damaged by potholes or punctures, but could have been removed from vehicles scrapped due to accident damage, sometimes severe.
I’ve never heard people speak of buying ”part worn” shoes, lawnmowers, or engines. They’re simply referred to as either “second hand” or “used”.
I’m not sure many people would buy “part worn” brake pads or brake discs, but due to to the costs involved choose to buy used tyres of unknown history or source.
I understand why, because there are some, including many used car dealers who view tyres as nothing more than a neccesary evil, and will replace them only when they have no option either through damage or MOT failure, and will go out of their way to pay the absolute minimum for one that will get them mobile again, irrespective of age, condition, make or tread depth. They will then drive off having paid £100 for a full set of tyres and an MOT certificate, wearing their £200 trainers and at the same time texting their mates to tell them of their bargain.
I’m sure most people would agree that aside from their obvious function, tyres are a safety device, even more so than a crash helmet, which unless an unfortunate incident occurs, is redundant throughout most of its time in use, unlike tyres which must be relied upon for every second of your journey.
Still, as they say in motorsport ...
If you’ve got a 5 dollar head, then get a 5 dollar helmet !
