It might be that, but most old dry rot I see takes the form of crazed checking, or spiderweb cracking.
I ran the tires at 85 PSI, which turns out to be underinflated. Why I thought 85 was ok is detailed in my long winded post #20 in this thread.
Anyway, looking at the tires, I see "1618" hot stamped in the sidewall. Everything else is moulded in. No way for me to know for sure, but taking into account European date style, 1618 may represent June 1, 2018.

In addition to being exposed to ozone, chemicals, etc., mentioned already it would be good to know the production date of your tires. Tells how to find the date here. https://www.continental-tires.com/bi...e-construction

Thanks for the photo. It makes me think of dual compound tires. I haven't kept up with tire tech in a while, but I remember some tires were made with a harder compound down the middle with a softer compound on the sides.
