[Mgs] FYI

[Max Heim]

That’s what I was suggesting. Temperature was also raised as a contributing factor. Exposure to ozone is another I have heard. But how long, is the question?

I wasn’t ready to give up on mine yet. But YMMV. Poor Jay Leno has hundreds of cars, all of which are valuable, and which he likes to drive regularly. So keeping that stable shod has to be a massive ongoing expense (especially considering that many of them have unique or uncommon tire sizes).

So they might date back to 2014 or even 2012. Still at least 70% tread left and the sidewalls look fine with no cracking. They have always been parked out of the sun under a carport with a car cover. I am not too concerned about sudden failure since they contain inner tubes.

>> Many 'authorities' advise that a tyre should be examined closely at 5 years and replaced when it reaches 10 years old irrespective of wear.  This tyre was 12 years old but had only done 18k.  Certainly not mileage expired and if just 2 years over the 'recommended' change point is enough to cause this then I suggest it was either faulty or they are just not made to the standards they used to be.
