I dug several mm long glass shards out of my Schwalbe Marathon+ without them penetrating to the tube, but if you want solid rubber, you can buy it: https://tannus.com/tires/

Thanks, this sounds great. But 2 tires cost more than my whole bike :/ Not that I can't afford it, it just feels wrong somehow :)

Just compare it to car tires and it doesn't sound so expensive anymore :)
