Blimey, hold on a minute.

Apparently some 3.5 million part worns are sold in the UK each year, and afaiaa all/most have come from other European countries and from cars just the same as we drive.

For those part worn tyres to be 'probably kerbed' then our tyres on our cars right now must also be probably kerbed too, right? If not, why would the part worns be? I don't think people in other countries make a habit of driving up kerbs any more than we do.

Leaving aside the fact that we're all driving on part worns right now, every used car is sold with part worns and I've never heard of anyone insisting the tyres are removed from the rims for inspection, which would be the only to do it properly.

Has anyone here who has bought a used car even just had the car placed on a lift and examined the tyres properly themselves?

I own a small garage business and obviously we service cars daily, and we find metal detritus in tyres *all* the time, so we must all have tyres the same.

I've never bought part worns myself and I prefer a quality, branded tyre, but I don't think the arguments being raised hold water, especially the 'probably kerbed' one.
The probably kerbed relates to the tyre in the OP which catastrophically failed. Things may be more strict now but when I was younger there were quite a few heavily damaged part worns in circulation.

That tyre could've done a decade and 50,000 miles on the rear axle of a FWD car- constant UV exposure, thousands of heat cycles, possibly under-inflated, possibly severely under-inflated... You just don't know. Part worns are generally a false economy.

Hertz, Avis, et al, using part worns??? I'd be amazed if they did...
They put brand new tyres on for every new hirer? I'd be amazed if they did...

Surely, by definition they are part worn. They've been used by other drivers before you. You don't know the history of them. How they've been treated /inflated/kerbed etc. You still happily hire the car?

When you buy a used car do you replace all the tyres straight away?

Where are they coming from though? Given that we're allowed to run our tyres to a lower tread than Germany (which is where most come from, I understand) how are we doing less damage over a longer time?

You are taking a greater chance than if you bought new. Your life, your choice...

I ran part worns when I was young and foolish, it doesn't work out any cheaper.
No, I'm taking the same chance as when I have bought any number of used cars, or borrowed a car, or hired one. Less chance, in fact, because when buying used tyres I look pretty damn closely at them to see what I'm getting.

Most of the time, if I need tyres for something, I'll buy new. But if a set of wheels comes with good tyres, I'm not going to waste them.

You're not taking the same chance. New tyres won't have been in a crash, part worns may have been. You seemingly don't understand how this chance malarkey works.

Hardly a fair comparison. I know a lot of the part worn are taken off fleet cars under a maintenance schedule, but a similar amount are taken off cars because the owners know they're fked.

I can understand someone fitting a part worn to get them through an emergency, but someone that's trading and fitting them is a .

I've flicked through this post but not properly , is it not possible the op picked up a slow puncture on the way home , didn't clock it the next day and drove on an under inflated tyre that then blew out , just like a brand new one would ?
No doubt I'll be corrected immediately as I'm to lazy to read all the posts ?

Can I ask if the tyre had "part worn" permanently stamped on the sidewall when you purchased it? Also, did get given a receipt? I'm im the tyre trade and things like this interest me!

I think it might have been just a tad bald if it had.

And you don't seem to have read what I actually posted, and are instead making a strawman argument that I was saying a part-worn tyre is as good as a new one. I wasn't. I was saying that buying a set of previously used tyres on their own is comparable to buying a set of previously used tyres with a car attached to them. And we do that all the time.

So, if I buy a used car, hire a car, or borrow a car, the tyres on it will be brand new? Or will they be tyres that have been used prior to me driving on them, i.e. part worn?

No-one's saying part worn tyres are comparable to new tyres. But part worn tyres are absolutely everywhere, they're on every car not sat on a tyre fitter's lift right this second.

Not meaning to sidetrack, but I'd always thought the German limit was 3mm with a few additional rules like not getting stuck in the snow on summer tyres?

I had a MK2 Astra that covered >80k miles on the original rear (Michelin) tyres. Even then they hadn't worn to the legal limit!

Yup, when I did the first set of replacement tyres on my car I did all four within 5,000 miles. 20,000 miles later the rears still had more than 5mm of tread, and that's why it's important to rotate rear to front on a FWD car.

I can't agree with that. I don't think they're always a good idea, but I'm not a big fan of wielding the banhammer as a unilateral response. I've bought used wheels and tyres before and had no problems, sold old ones on and not had anyone say they had an issue with what they got.

I deeply dislike preventing people from being allowed to do something which is not innately unsafe or problematic, when the real solution is taking a little care and using common sense.
I guess we'll disagree then. I won't do secondhand tyres as I don't know the history of them & for the tiny bit of rubber between myself & the road is an unnecessary risk. I resent others potentially crashing into me for the same reasons. I wonder how many people who can't afford new tyres have the requisite 'common sense'?
What do yo do when you buy a second hand car then, put new tyres on it?

Well yes, actually...

But then I regularly rattle up and down the Autobahn at warp factor snot, so I consider high quality tyres to be rather important.

It's not usually about tread. Germans replace their tyres based on age (usually 6 years), and that's why we get their used tyres. How many people (general public, not the good PH collective of course wink ) read the DOT number on the tyre?

Nope. 1.6mm at the lowest point both for summer and winter tyres - at least that is the official rules. However, in wintery conditions if your winter tyres are below 4mm, it will heavily bias any blame (and potentially insurance payout) in the event of an accident. Winter tyres have 4mm and 1.6mm markers in the tread.
