I run tubeless no snakebites this way and with snakeskin sidewalls they take a pretty herd beating...what tubes are you running with schwalbe tires? single ply 2,5 in front sounds like good idea.. how foldable hold up in ust and non ust versions?
Id run freeride over the UST, I like UST and they have there place but they are a bit more flexable than I like and they dont have a snakeskin sidewall... The freerides hold up to stans amazing and I have had NO ISSUES with this on a multitude of terrain and temperatures...
If I ran freeride and I tubed Id probably go DH tubes, or welterweights and more PSI. Snakebites will happen with almost any tubed set up...
Id get a 20" schwalbe tube with the threaded schrader valve slice and dice to a ghetto tubeless setup its super easy and RELIABLE... Had 2 snkaebites by fellow riders in the rocks on last nights shuttle and none for me... Ive had 1 issue I put a jagged rock through the tread and dented the center of my rim so any tire would have taken a beating ....
