Date of manufacture

[xtpete]

just wondering how meany of you's realise the date of manufature
is stamped on a road motorbike tire... some dirt tires...

I just got this Shinko 705.. ordered it online...
it's already 2 years old.. Something I check
before buying from a shop but online yer can't...

Date code on this one is "2711"
Made in the 27th week of 2011
yer can see the stamp was held in the mold by 2
philips head bolts...

so theres a bit of useless info for next time yer buying tires
if yer don't already know...

((MODS.. move this to the tire section... don't know how /why I put it here..))

Helmets are date stamped also. Things that deteriorate with time, maybe? But how long is too long?

Just received two Shinko Raven 009 tire and both are less than six months old.

I've read elsewhere on tires that 5 years is acceptable. By that I mean if they are stored correctly (away from sunlight and ozone).

Bingo correct! 5 years for tires, helmets and leathers. Moister content leaves these products. All three should not be used after 5 years.

Personally it is a risk whenever you buy "blind" from any shop (internet or post etc).
It is also to me, ok for a 2-year old tire. I am sure many shops also have stocked them for 2 years, and then they give sale, etc.
Internet shops usually give a huge discount because they do not stock their inventory, they just place an order to the direct factory or a wholesaler, who will probably sell you the "oldest" stock first.

It is not unique, just look at your supermarkets. Milk, yoghurt, eggs, etc....

PS: Do you seriously expect a tire from say made last month?
Not unless you live next to the factory.

I always wonder if the tires used for the US market are the same as for the UK one,
as US riders seem to get many more miles from a tire, are they exactly the same
or maybe a different compound in the US?

Maybe road condition plays in as well? I don't know how good your streets are in the UK, but even from state to state here there are HUGE differences - I live in Louisiana and crossing the state line into Texas feels sooo smooth! I think any of my tires would probably last longer if I drove on TX roads instead of LA. Our roads are... not really a point of pride for the state

I am sure road conditions do play a part not only are the uk roads poorly
maintained but except for motorways we don't have many places were you
can run at a steady speed, in the last few years they have switched to a
different tarmac mix that is much quieter and hopefully better on tires, but
there still seems to be quite a big difference between US and UK.

Most U.S. states do not have safety inspections looking at tire wear and some of us run them longer than we should.

The "youngest" tires I have ever bought were the Michelin Pilot Road 3s on the bike now. The pair was 4 months old in June 2013 when I received them. The youngest tires I have ridden on were a month old when Bridgestone shipped them from Japan for a beta test on my ST1300.

When the years of sun, sweat, wind, and rain have faded the date stamp so badly you can no longer read it.
