Debunking the tire age myth

[LAB3]

Here's an interesting video that come across my news feed this morning about tire age. It shows a guy testing a brand new set of tires vs a seven year old set on a track bike and finding no difference in the amount of grip.

it serves to show what I've been saying for years, truth is more a function of what people say amongst each other regardless of the facts! Get ready for the "whatabouts" after seeing this, another common theme when "truths" are debunked.

Of course there are "whatabouts." It's because they are valid. Such as, how was the 7-year-old tire stored?

Uh, I'm pretty sure he covered that in the video.

In about 2015 I bought a rear wheel just to have another spare ready to fit. Like many wheels you see for sale, the seller wasn't willing to strip the tyre off it, but the price and the shipping was cheap, so I went ahead with it.
When it arrived I was surprised to see that the tyre was an almost unused Conti Blitz. I carefully examined it for dry rot and any other defects, but found none.
It eventually wore out, but turned evil during the last couple of hundred miles, when there was still at least a good thousand miles of tread left, so I binned it then.
I counted that as a bonus buy - never did figure out the DOT code, because it was only a 3-digit one.

Open air vehicle pools use covers for tires.
sunshine and heat are nasty to everything.

We used to get tires that you could see were left in Sunshine. I think that a lot of tires people think are new are in fact a lot older than you may think. The Pirelli Diablo's smelled, and had a film on them that made them feel they just popped out of the mold.

Gotta agree with Nessism here, how they are stored makes a huge difference. My bikes in my Barn, which breaths, but has no Sunlight keeps the tires are great.

That's because it was stored in an environment SO perfect that tire scientists use it today in order to calibrate their instruments.

How old does a tire have to be to not have the 4 digit date code?

From the ancient times, before Al Gore invented the internet (pre 2000)

20th century, they dropped the 19, so you get the year 9, and week 00, for 1999.

I suppose what it boils down to is that if you are putting your neck on the line, who do you trust more.
I've ridden a set of practically new Pirelli Street Demons this year that are at least ten years old with no complaints but were for most of that time stored in a dark corner of the garage.
Green light does not mean safe no more than red means no go. There is a long German word I forget which means, in essence, finger feel it to know.

Just a funny aside - my '82 Mr Turbo came with the original Bridgestone 'Mag Mopus' with nubs still on. Stored in a garage all those years and no visible cracks or rot. I used them to roll the bike around the garage while I worked on the 18" EPMs, hacksawing off the Goodyear slicks. Those originals have been good on a museum piece perhaps but they're long gone now. Very tough to pry off. Those pristine '82 rims with brand new '82 sprocket fit perfectly on my 79 GS1000E
