I bought 4 part worn Continental tyres today.....
They let me have a good look at them before they were fitted and they all have 4 - 5 mm of tread left, and are generally in good condition... :y
The 4 tyres cost £120 fitted and balanced which I'm pretty pleased with, and I'm hoping being a good brand that they'll last nearly as long as a cheapo set!!
What do you think Guy's and Gals?? :-?
-
I have major concerns about them, mainly becuase they dont require testing before being sold and many come from accident damaged cars.
Now of course, the accident may have been little more than a shunt but, what if it wasn't and caused unseen internal damage.
-
check the production date.. a tire older than 6 years old must never be used..
ps: which my experience says 5 years..
-
I suppose by nature of a tyre being fitted to a car it is immediately a part worn. I know quite a few of these tyres come from Germany where you have to replace both tyres on the same axle in the event of one being damaged etc but as Mark says, you really don't know the history.
I have a couple of cheap tyres fitted to the front of my DTi that came with a set of wheels I bought a while ago. I only fitted them as a stop gap when the wishbones were worn out and eating tyres. Really trying hard to wear them out (not easy now the Geo has been done!) and will pop some Kumho KU31's on as per the rear wheels, seem to be a good balance of performance / cost.
-
Yep, that's a fair comment Mark.
The guy at the tyre place reckons that they get them from Germany where lots of people just fit new ones rather than hang on to the old ones when they swap winter tyres for summer... ::)
It might be good story though and I can see your point of view! Thanks :y

but at least you can check the inside of the tyre for damage, which is more than you can on the tyres of any second hand car you might buy. ;) ;)

in the past i have used part worn tyres and can not complain have had some good tyres,but each to their own,just put new on now,but as i said have had some really good part worn ones can not see a problem with it :y :y :y

My personal view ..... the only thing that keeps 2 tonne of metal being propeller by 217 Hp on the road are 4 very small patches of rubber.
Even when skint I will not put suspect tyres on. And I include cheap / part worn under suspect. If I can't put something at least half decent on .. I won't drive it.
My life, and my wife and kids lives, might depend on those 4 little patches of rubber some dark and wet night ...... and I don't want to think about the consequences of them not doing what they should .... :(

TBH I would have no issues with them if they were subjected to a basic run test (as per new tyres).
They must have PART WORN marked on them in at least 4mm writing to be sold in the uk (which might give some indication of the honesty of the seller)

Argueably lower risk TBH as you cna see the condition of the car and rims they are fitted to.....of course they could be part worn ones........ ;D

They have/had to have a rubber label on them.
-
That's also a very fair point Entwood! :y
My last set were also part worns, Pirellis and Michelens and they lasted longer than the cheap brands I had bought before... I thought it might be a contentious subject here... :)
As I said they did let me examine them and they seemed in vey good shape, although I do take Mark's point... I don't know whats happened to them and maybe there's internal damage to the structure... :-/
Every time we buy a second hand car though, we are also buying secondhand tyres and how many people go out and buy new tyres just because they don't know the history? ::)

True, but as I say, all my cars have had 4 part worn tyres on them when I bought. I have bought part worns in the past when I was younger, ....

There you go..... I'm still young :y ..... ish!

No .. the paperwork with the car showed the tyres had been bought new some 2 years previous ( just checked the receipts in the folder .. :) ) ... but they were replaced within 6 months as I could not get on with them ... linglongs (?) .. didn't like the way they handled.
IMHO .. tyres on a used car are LIKELY to have been fitted as new .. they might not of course .. but probability ???
who knows .. and everyone is entitled to their opinion anyway ... mine is reasonable quality rubber .... and as I've somehow managed to drive for the best part of 43 years without killing myself .... I'll stick to that !!

IMHO the only way i have been able to run a car for the last 6 years is partly down to the fact i could get hold of part worns and get them fitted by a mate for a few quid.
Without this option, i would long have been pushed off the road. Fuel, Tax, INSURANCE (being a younger driver), and all the rest of it are hard enough.
I WILL NEVER pay £100 a corner for tyres....It just wont happen.
-
Don't have a problem with the personally. But as i'm fussy (apparently) i'm happy to pay for tyres I want and know will work. Rather than take lucky dip on what turns up in axle pairs at best.
Btw, two cars I have owned had dinged rims, and potentially damaged tyre, on the inside rim, not spotted on inspection or test drive at the speed allowed by the salesman before he starts panicing. Get the car home, drive it as I would drive it and the vibration becomes clear. One car was bought at auction. What can you do? As Andy says, used car, used tyres, it's the exact same risk. Although any serious damage would be more obvious of course.

check the production date.. a tire older than 6 years old must never be used..
ps: which my experience says 5 years..
Why?

I've just changed the tyres on my trailer as I decided the old ones were a bit beyond the joke. Starting to show some signs of cracks in the sidewalls.
Apparently my Grandad gave this trailer to my Dad before I was born (so we're talking 1960's) and it had these tyres on then. :o
-
IMO, a replacement brand name part worn is safer than many of the Chinese budget tyres. Had it not of been for the availability of Part Worn tyre, my Miggy would have been off the road when I was made redundant 2 years ago...
I always have a good look at them and keep a close eye on the tyre pressure for the first few days... The only thing I will say is make sure you get them to change the Valve (many places don't)
-

Why?
do you eat a curry after a month in a refrigerator.. ;D
answer is simple, like everything tires are bond together with chemicals.. there are some oils used in tires which evaporate with time.. and when tires dry up the bonds start to break.. 6 years time is a norm which is also accepted by proffesionals.. however it can be shorter depending on the conditions which I found it to be shorter for here..
"The British Rubber Manufacturers Association (BRMA) recommended practice issued June, 2001, states "BRMA members strongly recommend that unused tyres should not be put into service if they are over six years old and that all tyres should be replaced ten years from the date of their manufacture
More recently, The Japan Automobile Tire Manufacturers Association (JATMA) recommended practice issued May, 2005, states "customers are encouraged to have their vehicle tires promptly inspected after five years of use to determine if the tires can continue to be used (recommends spare tires be inspected as well). Furthermore, even when the tires look usable, it is recommended that all tires (including spare tires) that were made more than ten years ago be replaced with new tires. Additionally, because in some cases automobile makers--based on the characteristics of the relevant vehicle--stipulate in the owner's manual the timing of tire inspection and replacement. Please read and confirm the content of the owner's manual."
Several European vehicle manufacturers of high performance sports cars, coupes and sedans identify that "under no circumstances should tires older than 6 years be used" in their vehicle owner's manual. However, it should be noted that European recommendations must include driving conditions that include roads like the German Autobahn, which allows vehicles to be legally driven at their top speeds for extended periods of time.
While American driving conditions don't include the high-speed challenges of the German Autobahn, Chrysler and Ford Motor Company joined their European colleagues in 2005 by recommending that tires installed as Original Equipment be replaced after six years of service. (General Motors declined to offer a recommendation until a more scientific analysis of driving conditions and tire aging could be completed)."

it depends.. if you prefer a 2mm thread famous brand old tyre with an 7-8 mm new chinese tire, I'm afraid you will loose the bet.. apart from that tire age is also a very important factor.. when the tire looses its softness even tire with a 7-8 mm thread can not be considered safe ..

:o Blimey Chris, you've commented on a tyre thread without once mentioning Falken's!! ;D
On a serious note, I picked up a set of original MV6 wheels from egay last year that had 4 part worn (almost new in fact) Dunlop SP Sports fitted and they're still going stong. I'm buggered if I was going to chuck away 4 perfectly good tyres and fork out for 4 new one's! ::)
-
Not something I would do to be honest, although I have in the past (more to get correct wheels though). But I wouldn't change the tyres on a 'new' 2nd hand car until required, so thats no different.
I think Lazydocker thinks I should change those useless Michelins on the Elite... ...but he was sat the side that was about to be jousted ::)
-
Part worns have recently struck me as a cheap way of trying various tyres without making an expensive mistake.
That said, they do worry me being your only contact with the road, and I am not sure I would ever take the risk.
I appreciate they are little different from buying a 2nd hand car but would like to know the history and that it had been tested to its original spec.
-

Like I say, I'll check the tyre first, and I'll only have a tyre that has at least 5-6mm of tread.. And with the roads I have to drive on, there is no way, I would consider budget tyres...
-
there really is no point selling a partworn with less than 3mm, and realistically, the only ones worth buying are 4-5mm+
You're getting half the tyre life, for much less than half then money of the original tyre.

Explain?
If a new tyre has 8mm (most do, some have 10...but for the sake of this example it has 8)
if you take away the minimum legal tyre tread depth of 1.6mm, which leaves you with 6.4mm of useable depth when new.
Half of this useable depth is therefore 3.2mm....which when combined with the 1.6mm or legal requirement gives you 4.8mm of tread.....which is half....
i think i'm right
but correct me if i have made a mistake in those calcs
-
and with regards to fitting costs,
even if i pay £10 a corner for fitting and balancing....which is the going rate around by me (a steep one at that),
i still save massively on the original cost of tyres.
A new 225-55-16 tyre for the omega at the cheapest of the cheap new is £65 fitted near me.
A decent make is more like £100
it costs me £10-15 for a decent make partworn with 5mm tread, plus the £10 fitting and balancing.
i'm out £20-25 for half the tyre life.
Yes please

from a quick search methylnaphthalene is the best material as factories also use that.. but its extremely dangeorus for health and dont know they sell it ready to use :-/
-
i've been using part worns for 6 years and never had an issue....not one problem.
Me too.
In fact when I got my Toffee box MV6 wheels refurbed, I had Conti part worns put on. Never a problem at all. Interestingly enough, when I took the tyres off the CDX wheels that had been fitted 'new' (so the dealer told me when I bought the car) - they were all puncture repaired.
One cheeky bastard of a car dealer (what's new?)
When getting part worns I always check 'em over and get them tested on the wheel, and so far never a problem.
As I currently have 452's on my 19's (now I know why my car likes to make sudden, unexpected detours in a different direction) I'm looking for part worn Contis or Potenzas to replace 'em

As this thread has now gone off on a tangent and missed my original personal original point, I will re-state it.
A large percentage of these second hand tyres come from written of vehicles.......i.e., they have suffed an accident bad enough to cause them to be beyond economical repair.
Now clearly if you buy a second hand car, its normaly pretty obvious the state the car is in and hence you have a much smaller risk (and its all about risk here)
And as for the second hand tyre seller saying its the likes of the Germans dumping good tyres when they change to winter ones, thats a load of rubbish as they have a second set of steel wheels with the winter tyres on (as you dont want chains on good alloys ideally!).
Now clearly an inspection is a way of helping to minimise the risk but, I personaly wont use them until there is a compulsary tyre test introduced for them which is carried out before they are sold (and to me its crazy there isnt as they are sold as fit for purpose). :y

yep.. and in case they are scratched by the wheel-shop some fight like I did saturday :P
-
The tyre industry may well voice concerns, they are loosing sales...
While obvious safety risks need to be essesed it's equally criminal to bin some of these tyres.
-
Part worn tyres are of varying degrees.
Some come from Germany due to the 3mm wear limit.
Some come from accident damaged cars.
Some come from cars where the owners change them to a preferred make rather than whats supplied.
Whats required if you want to use them is that you assess the risk and, like Mark, think there should be a universal testing standard so that they can be properly tested and graded.
When I ran my Cavalier TD - from 6 months old until I scrapped it withalmost 200K miles on - I used to use part worns at times. Back then, two young kids etc etc money was quite tight. I was choosy though. The new panda and other cars came fitted with, as I recall, Michelins, from the factory. The fleet ran on Goodyears. Result was that Tyre Services/National Tyres were contracted to change all the tyres and I then purchased a few of these 'part worns' from them afterwards. The wear was, literally, factory delivery miles only.
So, there are degrees of wear out there..... :y

As you would expect but, RoSPA are more independent and presonaly, if I was buying somehting as important as a tyre and it had a high probability of coming from a vehicle that had been invovled in an accident, I would want a basic test done before it was mounted on my car. :y

internal damage to carcass can not be seen easly by eye inspection.. :-/

And of course, if buying a second hand car, one could argue that the previous owner has carried out a 'running test' for you (at thier risk) :y ;D

New tyre is 9mm normally, tyre worn out at 2mm, nobody takes down to legal limit surely
I can assure you that wear rate increases as the tyre wears. Assuming it didn't, that would still be 5.5 half life. But it does. And by more than just circumference difference

Actually.. they did a track day like that.. in the wet (obviously not teeming down with rain, no standing water but wet track) and they gripped fantastically once they had some temperature in them..
Needless to say they're not particularly a 'road' compound ;) [edit] Although they are a road tyre - Yokohama Advan Neova LTS, original fitment on the S1 Elise, but they only last 5-6000 miles so they are a very, very soft compound!

They're awesome tyres with some tread on them :) Absolutely the best thing this side of a track compound on the MR2, IMHO anyway..

if you mean because it coss them money!
And those tyres have already been through a fit for purpose test when they were new.
If you are indeed proposing some kind of test, then maybe you should make every driver have their wheels tested every 6months as a precaution. because technically, any tyre becomes a part worn once its been used on the same car for several thousand miles........It's the same thing.
Every car is on part-worn tyres.......because tyres are a consumable item.
They wear down,
They are replaced.

yes i take my tyres to the limit.....but no further,
and if its winter i'll change hem slightly earlier becuase although i am aware, and take account for the change in handle characteristics as the tyre wears, a tyre at 1.6mm is much less effective in the wet.
The legal depth is 1.6mm.....so no reason why people would not take it to that.
In fact.....i see literally 10 or more cars a day....with less than 1.6mm of tred on, which i dont condone, but hey ho, what you gonna do.
I've been in the position before where i couldnt afford even part worns, but still had to drive to work.
I'm not proud of it, but i did what i had to and no one got hurt.

I count myself lucky if an Omega tyre gets down to the limit across the whole tread before one of the shoulders is down to fabric. ;D
In seriousness, yes, 1.6mm is about sensible. I find a tyre is still performing well enough in the dry at that level but starting to get a bit dicy in the wet and it's not something I'd want to run around on in the winter.

what sort of test would you suggest?
I, personally, buy from a part-worn supplier who I trust, having dealt with him for 15 years.
He checks his tyres visually on receipt and I insist on having them pressured to 60psi on fitting, then deflated to correct pressure before installing on the car.

The standard test used on new tyres e.g. an inflated, loaded and at speed run test (they have auto rigs to do it).
-
by the time that's been done on *every* part worn tyre, there would be no point in buying them.
I assume that not every new tyre is tested in this way? Just a sample of each batch?
I think I'll take my chances

No, all new tyres are tested that way.
Its not a long test.

Just remember, I am saying that I would buy part worn tyres if I could see some evidence that they had passed a basic test to prove they are not damaged as a result of thier previous life. :y

that's fair enough :.)
I just can't see it being economically viable, tho.
Fit a tyre to a wheel.
run test
remove tyre again
gonna take, what? 15 minutes per tyre?
that's going to add at least 10 quid to the price, not even taking into account the capital expense of the testing machine itself.
Worthwhile in the case of a big, heavy, fast car like an omega, I suppose - I think I'd take have them tested if it was available, certainly for the front tyres

it would be interesting to see a test of some tyres to see how many already fitted to cars would fail.
By which I mean tyres which were fitted to the car new, and run on the car, without "accident" for say, six months?

All new tyres are tested individually. Its an automated, high speed, rig with no manual input other than as an overseer. Test takes literally seconds per tyre and it is how tyres are graded for OE and aftermarket and/or discarded for out of balance.
The tyre you buy at an aftermarket outlet, despite it being of an identical make/size etc etc, is a 'second line' item and not first quality. They are reserved for the car manufacturers.
Look at a brand new wheel/tyre on a car in the showroom. The balance weights used are minimal, sometimes if any, in comparison to an aftermarket fitment, even when the aftermarket one is correctly fitted and located on the rim as per the light/heavy dots on the sidewall. ;)

How much would a machine to test part worn tyres cost tho?
Beyond the budget of a one-man-band tyre part-worn tyre fitting shop, I'm guessing?
Something that only a company like kwak-fit could afford?
I can imagine how *that* would end up... ::)

Probably a lot more, as, if MDTM is correct about written off cars, they have to lose the cost of the tyres that fail that would otherwise be offloaded onto unsuspecting Joe Blogs

Mmmm!
First place I look in for a new tyre is the scrapyard. :-?
They have to be looked over carefully of course but I've never had a problem. 8-)

yeah couple of time i bought a few 14" steels for my old mondeo with near new tyres on.
Were £10 each. saved on the fitting of the tyre then too lol
