The tires on my commuter bike (schwalbe durano) seem to get brittle and get these tears all the way through. I do keep the bike outside, but this has never happened with other tires.
Maybe they were old stock and detiorated much faster?

They are old and dry rotted. If they are not that old, the perhaps the bike was stored in a dry environment perhaps next to a draft, a dehumidifier, an AC vent, heater, or stored standing on concrete for an extended period of time.

When did you buy them?

They look like they are 30 years old.
If they’re not that old, is the bike stored close to a source of ozone or chlorine maybe?

Age, mileage, and exposure to the elements will degrade tires. Some deteriorate faster than others.

A car tire will have an age stamp when the tire was made
How old the tire is , is the question
Not when you bought it
Could have been in the ship for a long time
Next time look closely at the tire when you buy it
Maybe the shop will give you a discount on the new tire
I think schwalbe tires have a date stamp
The older a tire gets the more it turns into ‘dry rubber bands ‘
Of course if you live in a hot dry place
Or bike takes a lot of uv that accelerates the process

I had the same tyres as those, and after a year, they almost looked like yours. Even if I keep mine inside.
I know other people with Schwabe tyres having had the same issue. They especially seemed to degrade when not used much.

Some higher tier tires are actually more likely to do this, apparently continental gp4/5000 known for this also. Yes, keeping, unless you store inside, it will continue. Better and more supple rubber, I guess it breaks down faster.

Must just be crappy/faulty tyres that are exposed to the elements by keeping them outside. I’ve found old ones that have been in the garden or elsewhere that have showed similar degradation. Just get some new ones. Sometimes shit just happens. I had some Continental tyres that kept slipping on the rim and ripping my innertube valve. Never had that before. Bought a new pair of a different brand and they were fine.

Outside storage, sunlight (i guess specifically the UV spectrum of sunlight), and general weather will do that to ANY tire, its not limited to one specific type.

UV light will happily do that to rubber

Old age, direct sunlight, ozone, some chemicals.

Sometimes “new” tires have been sitting in a warehouse for 15 years, aging.

Ehhhhhh yeah you probably live in a hot country – that doesn’t happen to those tyres here in northern Europe

Have you always checked the pressure? Too little pressure causes side cracks, and too much can tear the profile, like in the picture.Or they’re simply too old, and tires have a lifespan. I suspect too old.

Jest regular old wear and tear.
Over several decades

Age probably. Some tyres last longer than others.

Are bike tires date coded like car tires? They look old.

UV and heat from sunlight. The more grippy (softer) a tire is with light compounds, the more sun and heat kill them

Bike mechanic here 👋 this is classic dry rot more than likely due to long exposure to the elements, this looks like expansion dry rot, even if you stored it properly outside, expanding and contracting happens from going warm to cold with the day/night cycle. As the day goes on the heat expands the rubber and as it’s cools off at night the rubber contracts causing these types of tears in the tire. Hope this helps!

You said you got these tires a year ago, so this should not happen that fast.
Ozone, ethereal oil, ammonia and some other chemicals can increase dry rot, and UV doesn’t help.
Something went wrong, either in QA, a long storage in the shop or something I can’t think of at the moment, but this is not an acceptable amount of rot in a year.

A few durangos have let me down now, 2 of them explosively. Made me change to the continental GPs and they have been excellent
