This looks nasty, but I wanna get a reality check on how worried I should be about this. I've been running them tubeless, typically aiming for about 35 psi. I've stored the bike indoors in my apartment. I've got the same sort of cracking front and rear. I'm reluctant to replace them already, because I've only used them for one season of frequent riding (though mostly pretty modest distances).

I’d be tempted to say you’re fine because that’s the sidewall rubber that covers the inner casing, though I’d also wait to see what others here say.
Potentially I’d also look into contacting whoever you bought those from and asking for a replacement, seems like they were either old stock or stored improperly. They shouldn’t do that after a year of being stored in a heated apartment.
They definitely shouldn’t be doing this, but I don’t necessarily think it’s catastrophic. Depending on how long you’ve had them installed, I would contact either Panaracer or the retailer you bought them from and find out if replacing them under warranty is possible.
I’d keep riding it if it’s not leaking. Gumwalls are always doing this kind of shit.
How old are these tires ? That’s the kind of thing you see on new old stock.
Tyres degrade with time it’s a pain but it happens, As tyres degrade they start to get stiff and crack. The issue is that unlike car & motorcycle tyres cycle tyres don’t have a system of markings to show how old they are so a tyre that’s new to you can have been sat on a warehouse somewhere for years before you buy it and may already show signs of failure.
Yours are nowhere near as bad as some that get posted here but they are definitely telling you it would be a good idea to start planning their replacements. If you can avoid amberwall tyres and go for black these seem to last a bit longer before they start to go.
