I have been offered a Michellin tyre (new) but date stamped 2012. Is this tyre past its sell by date? It is a road pilot 2 ,190/55/17. The size I want. They are not readily available .
Just dumping mine, they are 7 years old,dont want to trust them incase it rains,,but two years,should be fine
2012 to 2016? Even if they've been wrapped, sealed and stored properly I still wouldn't touch them. Is it just the pr2 you're having trouble getting in a 199/55? Over here it's probably the most common size of choice for 1000s.
I wouldn't for the sake of it, it's not just the age, it's the heat cycles too, if you come off and thought that a new tyre might of saved you, what would you be thinking n saying then ??
I wouldn't have any issues with using it, In principal, a tyre’s lifespan is around ten years, however a 'new' tyre is designed to last between one to five years if it’s properly stored when not in use. Both physical and chemical reasons cause tyres to age and this can also happen to tyres that are rarely or never even driven on. Compounds containing anti-oxidising chemicals are used to slow down the natural aging process of rubber. In this way, a tyre that has been correctly stored for long periods should still meet the specifications of, and perform like, a new tyre.
I'd say 2012 is fine. Anything 5+ years you should inspect annually for deterioration until 7+ years when I would then replace. Just my opinion and light research in the past. But... For the sake of saving a few quid, just buy a PR3 or 4 in that size. Shouldn't scrimp on tyres.
No worries, bit like me and pilot powers! Just a quick search but have you seen this... http://www.bikespeeduk.com/tyres-tu...ichelin-pilot-road-2-rear-tyre/prod_2649.html Worth checking DOT date for this maybe?
A quote from Michelin's web site. The 5 year test – before it’s too late! When they’ve been in use for 5 years or more, tyres must be examined annually by a professional mechanic. If they need to be changed, follow the bike manufacturer’s recommendations concerning the replacement of original equipment. As a precaution, any tyre which has not been replaced after 10 years must be changed, even if its general condition seems good and it has not reached the limit of wear.
When are tyres no longer considered new? Tyres are generally developed and produced so that the production features remain effective for their entire life span. Still, each tyre is subject to an ageing process, which also occurs during storage. Due to the different profiles, rubber compounds and constructions the ageing process is different for each tyre. The tyre manufacturers add substances to their rubber compounds, which slow down the ageing process. If a tyre is stored properly it will keep its full performance even after several years (up to 5 years) and will be considered "as new". The age limits generally is around 10 years - a tyre should not be mounted and used thereafter. If a manufacturer asserts different recommendations, they must be complied with. Test results: old tyres versus new tyres The tyre manufacturer METZELER has tested a set of motorcycle tyres aged five years and a brand new set of motorcycle tyres in racing conditions and has then compared the results. The five-year-old tyres had been stored properly. The old and the new sets of tyres were driven over a distance of 200 km and tested for 5 laps with the same motorcycle on the test run Vizola. The differences between the lap times between the old and new tyres were so minimal that there was no clear winner and that the quality difference could practically not be determined.
