Mouses are too much work.

2. Everything fails at some point...everything. Remember this post is about a Mousse failing. Been running tubliss since they came out. Knock on wood, never had (or seen) one single failure. I can't say that about Mousse or tubes.
There is nothing better then a reasonable broken in mousse. Traction is great, and a dead calm feeling.
But there is big difference in mousse size, feeling and weight and what tire you pair it with.
Mousse escaping tire I have seen several times. Typically when some try to run a 110 Michelin or Dunlop mousse in a 110 Bridgestone tire.
Dunlop rear mousse is around 4.2lbs, airmousse 4.4lbs. nitro around 4.1. Michelin (m199) is lightest and provide best feeling from new at 3lbs but holds up like shit. Maximum 10h.
Front I hate mousse. If I run it, I always try to run it stiff as hell so typically stuffing in another 5" of mousse from a old one.
Also had more issues with flat when I did run tublis. Soon as I hit something hard the air escaped.
The reason the one failed at Pala was because they broke the bead on the tire when installing it. Basically they stretched it too much. You can actually hear it pop when you do it and know it happened. Been there, done that, one time!
As others have stated you can use different mousses for different things. My son uses much harder ones when he is on the moto track compared to the soft when doing extreme races or Endurocross.
Down side is weight, but we’ll gladly take it not to ruin a race or even a practice day.
Tubeless is great, but slice a tire and your done for the race.

easiest way to make bike feel 100lbs heavier.
same with HD tubes, ill instantly notice a HD tube in a front tire in the first 50feet especially if im doing a wheelie.
I run 8lbs rear 8-9lbs front on at81s no issues on rocks logs etc
I have no experience with Moto...but for off road racing, as I look around, Tubliss isn't much better than a tube in terms of flat prevention. Trail riding, though? They are perfect for that.
For me? I've been racing USRA desert for 10 years on ultra heavy duty tubes...have had two pinch flats...ever (interestingly enough, they've both happened in the 2018 season).
Apparently, the particular rim that Ben was using is known as a double humper. Besides the outer bead (the sidewall of the rim), it also has an inner bead closer to each side of the raised center. That makes it really tough to get the bead of the tire into the raised section during installation with a mousse. Ben apparently made a late decision to change tires, and the installation was said to be a bit hurried.
Experienced installers (like the one who installed that tire) know if they've broken the bead wire. (Of course, so will everyone else in the vicinity, as it's quite loud.) Apparently Ben heard it pop on the track before it came apart.
Just as an FYI, Grant apparently got the brand wrong on TV. It starts with a P, not a D.
No matter how the mousse might be damaged or aged, this can ONLY happen as a result of something wrong with the tire or install damage.
The bead had to break for this to happen, as some stated (who seems to know the situation) Ben heard a loud POP and then it let loose… That was the tire band breaking. Most likely caused by hasty install causing damage to the steel wires in the bead.
“Exploding tube” can’t and won’t cause this issue. This is also why using a rim lock with a mousse is important, it helps to hold the bead on in the case of a tire failure.
This is 100% a tire/install problem, NOT a mousse problem.
