I never take chances with a flawed tire - I do live in the hills, so 60 kph descents are an everyday ride.

Tires do come off rims in blowouts, but you have cause and effect reversed.

A tire coming off a rim is a common cause of blowouts, but blowouts don't cause tires to come off rims.

In any case, even accepting the risk that the tire magically jams the wheel (which by your analysis is very small), how does that compare to the general risks of riding in traffiC?

Let's be realistic and consider that the risk of catastrophic failure is small, and the likely consequences of failure are minor, so, by riding this tire one is taking a small chance of an event that's not likely to have dire consequences. Now think about all the stuff that are far more likely to happen while riding every day.

That is the sillyest thing Ive ever heard. The chances of a properly mounted and inflated tire coming off a rim is just about impossible. I believe you are arguing for the sake of arguing on a subject you know nothing about

Ignoring the issues of my depth of knowledge or credentials, what you say is true.

The chances of a properly mounted tire coming off are slim to none. But the operative phrase here is "properly mounted".

Here on BF we have countless threads about tires blowing off rims, so it obviously happens fairly often.

But, we don't hear of it leading to injury, which was my point.

In any case, I was responding to a your claim that a blowout could cause the tire to come off the rim, which you now claim is just about impossible.

you are impossible. Please continue to give false information

I'm fairly cheap, but for a tire that runs around $20 new, I'd replace. And ride at rated pressure. There is a reason they don't list them for 50 and up.

Not to take this too far off topic, but how do you like them, crack notwithstanding?

I didn't ask for it, but thanks for giving me your permission.

You are right. I have a pair of 28mm tires at home. Maybe I will put one of them on the front and the non-cracked schwalbe on the rear (it's 35mm).
I like this tire. I think it's good value to price (without the cracks...)

Yea but no.
If the rubber outer layer cracks exposing the cords, then road grit gets into the cords and abrades them internally.
The general consensus among RV and heavy truck operators is that tire cracking means "your tire is very close to failure".

Replacing cracked tires isn't a big deal, as long as "not crashing at speed" isn't a big deal.

Also I repeat again, for those who think they know better--send pictures to the tire manufacturer and see what they say about the tires still being safe.
