Tyre insert fad has been and gone over the last few years. There are a shitload of options, not just cushcore.

Decent tyres are better than an inadequate tyre with something stuffed inside.

Dirt bikes are so much faster, heavier and powerful that comparisons with mountain bikes are mostly unhelpful.

So faster, heavier, more powerful, but the comparison isnt useful?

Just so we are clear, I don't have any air in my tire. No tubes, no messy sealant, no tubeless. It's a foam core. It can't go flat, and you get traction for days. It's not cush core, or any of the alternatives, which is where I think they went wrong, because those all still require air. Air is one of the biggest, if not the biggest failure on a mountain bike. They don't weight all that much either, I'd take an extra few ounces of rotating weight vs futzing with air trailside.
