Had a new one on me - rim tape split mid-ride, obvs no amount of pumping or even a CO2 was going to work. Using a Rockstop insert and Silca Ultimate sealant - I believe no combo of anything would have prevented this ride going south.
So yes, don’t trust single layers of factory tape (38mm Tesa 4289 on order).
But this is the second ride in as many months where a catastrophic tyre system failure has called an end to play - the other was a large sidewall cut.
Now thinking ‘what if’ had been miles into the hills instead of a 10min walk to a road for the Mrs to come collect. Removing a seated tyre with an insert in the wild does not appeal (snapped lever/fingers), nor does carrying a sealant-soaked insert like a bandolier all over jacket/hippack etc.
So am now thinking Tannus Armour inserts over tube. Positive feedback from a chap running a hire fleet that in 2000 hires they’ve only had 2 flats. And a repair seems much more do-able / tidy in the wild.
It’s an eMTB so really don’t care about weight, and Tannus+tube will be roughly Insert+sealant I reckon.
But what do they feel like? I’m running Minion DHR/F 2.8 and 3”, in the EXO casing. Will I hate my bike, or love the confidence?
Thoughts from people who have/are using Tannus much appreciated. Cheers

I didn't get on with them.
do you need an insert? a lot of the industry appears to be moving away from them. I'd try running no-insert and taking a spare tube with you, rather than a tannus which is likely to ruin tyre compliance (coming from somene who runs marathon plus on the road)
Having killed two £80 DHR’s with big impacts, and dinged up a few rims, I believe that are of benefit. If the industry is ‘moving away’ from inserts, what are folks suggesting solves the issue of the question inserts answer?
Is it higher pressure? That was always the answer - but grip etc.
Is it a new sidewall makeup that’s impervious to cutting when squished against a rim?

This is why I'm still lugging about a spare tube and a mini pump, the ultimate edge case can still be addressed by that "old tech". at some point you have to accept that every once in a blue moon you'll need to piss bout with a stupid tube and probably get covered in manky latex. sounds like you've had more bad luck that is typical of late.
My recommendation is having a couple of folded up Zip-lock bags or something stuffed in a pocket/pack for the next time you need to fold up and transport a soggy foam snake...
Have you tried just wrapping electrical tape around the rim for a few layers instead of official rim tape? I’ve never had it split on me with both ghetto tubeless and regular tubeless.
I have them in the gravel bike wheels, and really like them, and although they do alter the ride a little, they aren't as 'wooden' as you might imagine. But, I did also try one in the back of my 29erMTB, and really didn't like it in that siuation - they made the wheel monumentally heavy and sluggish.
Yeah, would be curious as to what the 'new' answer to inserts is. I've pinched tyres against rims and also dinged rims so gave assumed I still need inserts.
A winter on narrower CX tyres pumped up harder has made me think I could afford an extra 5psi in my gravel tyres right enough...
Im worried that my feedback might not be a indication of how everyone else gets on with Tannus, but I absolutely hated it when I tried it. Felt so heavy I thought there was something wrong with my bike. Squelchy too.
a lot of the industry appears to be moving away from [inserts in tubeless tyres].
this is news to me!
OK its not the previous de-facto answer to anything and everything that it was a couple of years ago (see other fads such as adding fork tokens, putting a shorter stem on)
But they seem to be useful, and used, by a large variety of riders of all abilities and intentions
