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..... Thumbs Up!

Some intersting and well considered advice here:

http://www.rospa.com/roadsafety/adviceandinformation/vehiclesafety/tyresafety/ty...

The tyre industry continues to express concern about the sale and use of part worn tyres

about says it all! Roll Eyes

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. Thumbs Up!

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.

half life is approx 6mm, you have to take into account fitting costs...

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

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 Wink

[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..

I er.. couldn't comment what they drove like on the road in that condition. On account of valuing my driving licence!
