It’s a funny sort of artificial terrain in a lot of places.
The Llanberis path, is a mix of fast smoothish bedrock/gravel, that you can absolutely hare down, but that leads you into much larger, steppier, & sharper short sections, where line choice matters, and the ability to hop the bike over stuff confidently and at short notice (especially if you’re busy looking at the front wheel and not down the track far enough 😉
Telegraphy valley is a very smooth fast wide track, but has pretty sharp steep waterbars across, so get your timing wrong and your tyres/rims are going to get a beasting.
In places like the Lakes and the Peaks, the terrain is much rougher, and looser, so it’s difficult to build up quite so much speed (without being a skilled confident rider in the first place), and so what i would call “catastophic” tyre impacts are not as prevalent ime.
It’s also perhaps, for quite a few riders, their first taste of riding on a steep enough gradient where braking is not optional, ie, you gain speed very quickly when you come off the brakes, and so controlling your momentum is a requirement. (Lets face it, in most of the UK, you can ride for most of the time without even using your brakes!)
