Hi all!

Iíve got a new (to me) fat bike. This winter I have gotten burp flats any time I ride with my pressure below 6 psi. Both times it was on my rear wheel which is a 27.5 Mulefut 65. The first time I was running a Vanhelga 4.0 tire which had come with the bike but had new sealant in it (Orange seal standard mix). Thinking that the tires might have been too worn, I replaced them with new Vee Tire Snow Balls in 4.0 and Orange Seal Subzero and it happened again. I talk to people on the trail who are running 4 psi or less and they donít have any issues. What could be going on with my setup?
