Nested Fat tires

[Vin]

Hello:
I have read elsewhere on these forums where someone came up with “recipes” for nested tires to prevent punctures.
I have searched YouTube and googled to see if it’s a common practice but found nothing.
Has anyone else tried this on fat ebikes? How’s the ride? Is 3-tire weight an issue for ebikes? How fool proof is it? Would you do this or go tubeless?
Example recipe: 4 inch, 3 inch, 2.4, then tube.
I have reached out to username “Sic Puppy” the writer of these recipes but haven’t heard back. His posts were usually long and detailed with a plethora of very useful information.

I'm not sure what you mean when you say "nested". Are you talking about using a spare/old tire inside of another tire? I've done that but it was years ago, it wasn't for fat tires, and it seemed to work OK but if I was having problems with flats today I'd be looking at the Tannus Armour , those seem to be getting some pretty good reviews. I'm not sure if they make them for fat tires.

Hi Vin,
I responded to your "conversation" inquiry soon after you contacted me. Did you not receive it? As for tire sizing: go 4",, 3.5",, 3",,etc.. To go in 1" increments (4",,3") will be too much-- use 1/2" increments at the maximum due to "dead air" space being excessive. Also, I too, am confused by the term "nested". Finally, on Feb 7th, 2020 I once again updated my thread on the M2S forum for Fat Tire recipe.. Also, thanks for the shout-out above..

I've never heard of this, but I'm hardly a fat bike expert. What I can say is that my fat bike rides are through areas full of prickly pear cactus and puncture vine/goatheads; I'll get dozens of punctures on a typical ride. I've run tubeless for several years now (currently 26" x 4.8" Schwalbe Jumbo Jims tires running at 6-12 PSI and Stan's) and I've had no flats. On some longer rides I'll need to stop and pump in a few extra PSI if I've really been running through the cactus, but beyond that it's easy and effective...those wonderful mid-ride tube-patching-changing experiences are now a thing of the past. I know some folks have been frustrated with tubeless; seems a lot depends on making sure you have 'tubeless friendly' rim. I'm running a Mulfut 80 up front and Bontrager Jackrabbit in the rear and both are real easy to mount tires on and seat.
