I don’t understand what you’re asking about.
Bicycle tires, even the toughest DH tires, are a lot thinner, lighter and weaker than motorcycle tires.
But that’s OK, since it’s near impossible to put as much stress on a bicycle tire as on a motorcycle tire.
Bicycle tires, even the toughest DH tires, suffer flats more often than motorcycle tires. But as far as traction and cornering is concerned bicycle tires do OK for their use.
Ah, it's you.
First your suspension is bottoming out, now you feel your tires are letting you down.
What's happening is that the world is trying to tell you that if you wan't something that can be ridden like a motorcycle, you need to get something that's built like a motorcycle.
There are reinforced ebike tires for road use, but I'm not aware of any reinforced E-MTB tires.
If you're stubborn enough, you can have wheel built with bicycle hubs and motorcycle rims.
it probably won't work though. Partly b/c a quick search indicates that motorcycle tires don't go bigger than 21", Partly b/c those tires are probably too wide to fit in your frame/fork. And it'll drop your BB.
If you're stubborn enough, you can cut the bead off a road tire, and fit it inside like a liner.
This is assuming what you're suffering from are penetration flats. If you're getting pinch flats, the correct inflation pressure, or possibly a tubeless conversion should pretty much fix that.
