I can´t believe these results ...
Even my old P Zero with less tread will beat every winter and all season type in dry and most also in wet handling.
It´s true than not-so-new winter and all season are better in dry than new ones, but they have still no change in dry against a summer tire.
Or is the test made at extreme low temperature?
I'm unsure of testing temperatures, but I'm certain it wouldn't be been at or even near freezing.
What about the speed the tests were done?
The write up indicated both were done from 60 kph which obviously isn't correct so we've left it out.
Dayton looks awful.
No arguements there
Maybe this test can be an answer to michelin's campaign, that worn tires are better than new ones.
Michelins campaign is highlighting that not all tires are created equal. They've independently proven their tires hold performance better than other brands as they wear, so this article backs up their campaign if anything.
That said, no one should refit a tire that's 7 years old and has been kept in poor conditions, so I'm not entirely sure the point of this test.
It is very odd...
I only used my own old tires as they had been stored well enough, passed inspection, and were closely monitored after refitting.
Pulling some out from under a tarp in the garden and banging them straight into braking tests, so to speak, is a bit random!
If testing worn tires, you want a set that are currently in use and have been since new... They've compromised the test so may as well have not bothered (with the worn summers).
I wonder if they run-in the worn tires first??...
I have found even a few months in storage has a profound effect that can take a couple of hundred miles to rectify. My old winter set of wintersport 3d and A001 were horrific once refitted after 6 months, the car would be a big handful in all conditions until the tread was scrubbed back in then all was well again, similar but nowhere near as bad with summer tires stored a while.
On my old car theres a michelin energy e3a which is nigh-on 13 years old now (was unused spare until 7 years ago)(I dont advocate using tires this old btw!) I kept it in occasional use after it was first used to try and keep it 'fresh' so to speak, despite its age it still performs well, solid as a rock on front in the wet (and better than new firestones) but ONLY once scrubbed back in...
(Yes, I know the dangers of old tires, but it has no age cracks even hairline, anywhere, has never been punctured, has been used intermittently since 6yo (still coated in release agent at the time) and always thoroughly inspected. But since it has no ageing signs, no compromise of structure such as a puncture, and, unusually for what tire it is, sticks like sh1t to a blanket, holds pressure astonishingly well (barely ever needs 1psi) etc, I continued to use it with close monitoring. (Though its had some serious punishment in use))
I would hope they'd have scrubbed the tires in before starting the braking tests (which are always done first!)
Tires can seep oils out when left in storage, which is why when refitting they can be a little slippy, especially in the wet!
Exactly, plus the outer exposed layer hardens, double trouble!
You've got to be mad to use a 13 year old tire on the basis of a visual inspection. Michelin recommend 10 years as the max lifespan. What car have you got? I'll steer well clear.
:-)
If you read properly, i havent just glanced over it, and note that I dont advocate using tires this old.
Im quite clued-up when it comes to tires, why old tires fail, why they are generally less than ideal after time etc.... This tire is an exceptional example, most tires of similar vintage would not be fit for use.
