I've used they them work great. For winter used only on snow you should not have a problem. Follow the instructions for install so they don't twist.
What rim are you using? I have one pair of wheels setup for fat tubeless and run stupid low pressure in sand without too much drama, however, I would like to find a tube that can withstand being run similarly. Sand and snow are a thing and I like being able to ride in less than favorable loose sand with wrinkly, spongy tire for the irreplaceable flotation only a fatbike can deliver. Other pair of wheels are Surly Toobs.I’ve run the tires as low as 2 psi for very soft snow riding. No issues with the low psi. Typically I run 3 Psi in the front and 4-6psi in the back depending on conditions. I like tubeless in all my other bikes but at these low pressures I can’t keeps the beads from separating thus the need for tubes.
On the snow they are the way to go. My winter wheels are 94 mm ones that are not tubeless or low air friendly. Maybe 5 psi is the lowest I dare go. I ordered mine from Germany but now you can get them in Canada eh. I also had a tube cut on a sand ride by sand in the rim lots of sand. Make sure your rims are taped/ sealed well.I do keep considering going with the Rev toobs but have a curiosity of how supple they are for low pressure riding. Since I do a large percentage of my fatbike riding with soft tires for the flotation that riding on near full tread width can offer, I really would like to be able to continue that.
RockyJo, you have some snow time with em, whaddya say?
What I don't care for is the mess and cleanup of sealants, so tubeless is kinda ok but a cleaner method to that would be awesome.
On the pinhole front... Been there with SL tubes where I had to immerse the tube to find the leak. Not the end of the world since I keep a reasonable supply of tubes, new and patched. SL's tend to keep the softness/suppleness a priority.
Fortunately, I have Clownshoe and Rolling Darryl for rims that I can run nearly flat tires with and drama free. Just wanna be able to keep it cleanly and such. Thankya, RockyJo!!On the snow they are the way to go. My winter wheels are 94 mm ones that are not tubeless or low air friendly. Maybe 5 psi is the lowest I dare go.
