    Cruising along standing up about 30 mph on Switzerland Trail in Boulder, CO and front tire blow out. I hit the ground so fast I had no idea what was even happening. Couple scrapes and scratches, luckily no big rocks in my landing zone!! Ah good times! FullSizeRender[5].jpg

    " Any idea what caused it? "

    Most likely UTTER STUPIDITY caused the blowout. Many riders automatically lower tire pressure when they go off road, to ridiculous low levels, because it " feels good ", and they just automatically follow " myths " they have heard about this. They go over a rock, the tire pinches the tube between the rock and the edge of the rim, and instant blowout. It is called a PINCH FLAT, caused by to low tire pressure....

    The bike in that picture has about 10 inches of suspension travel. If the rider is so fragile that he has to lower the tire pressure to get a smooth feeling ride, he should just stick to driving his car. Whenever I buy a new Honda, they always give me a safety manual that says in large letters on the front cover " STUPID HURTS ".

    JettPilot is off course as usual. Anyone with half a brain knows the lower tire pressure is for increased traction. And yes, a pinch flat is a calculated risk.

    Thanks for sharing your story with us.

    Jettpilot, you can add me to the ever-growing list of folks on here who believe that you are a butt-hole.

    You know,Jetpilot, they make the Tubliss system so low air pressure can be run without pinching tubes. I personally run 5-7 lbs on my Gas Gas to get as much grip as possible and I've got lots of susp travel.

    Tubliss is brilliant. But your running dual pressures really. 5-7 lbs on your "outer tire" and 80+ on your tubliss "inner tire". That is very different from running low pressure on a big ADV bike.

    Another thing to keep in mind is that if your running real low pressure with a tubliss system the "inner tire" of the Tubliss does give some lateral support to the walls of the "outer tire"... this is what makes the combination so damn good.

    I've run low pressure on the Tenere is deep sand washes and some rocky stuff, but you have to be very aware of rocks that might harm the tire or rim.
    I would also keep a damn good eye on the pressure using Fobo Bike blue tooth sensors with audio warning in my helmet.

    On a big 500lb+ bike I find that traction is not really increased that much by lower pressure, however the stability and less nervous behavior in deep sand washes really improves. Also makes for smoother front wheel control... the front wheel does not get "ping ponged" around as much.

    Running low pressure on ADVish bikes with alloy rims is more risky as it's easy to crack a rim and then your really in the shit.

    However it's just much better to do that stuff on a lighter bike.

    I don't see the tubliss giving my sidewalls any support as the inner carcus only contacts the tires bead where it seals against the rim. I've punctured ,or should say gouged , tires that were not pluggable and rode for miles to get back to my truck and the tubliss system kept the bead from unseating on the rim ,which was great, but otherwise the tire was flat and very hard to control. Now this is offroad only riding. I did some damage to the inner carcus but nothing major just some scuffing.At 5-7 lbs and basically riding rocks I've not put any dings in either wheel 'yet' but its a light bike and low speeds for the most part.

    Da*n man- again one of your trademark triple-long-jumps to a conclusion and, as usual, delivered with the tact and understanding of a lobotomized alcoholic father.

    LOL, if you haven't caught on that JettPilot is an immature trolling imbecile you're late to the game. I keep him off ignore for the "feel good" entertainment value he provides. After reading one of his posts it's hard to not feel just a little smarter than average. ;)

    Ha...yes, I am familiar w/ his "work" alright. I'm kind of surprised that I was surprised that he's still a monumental douche.

    JettPilot- if you ever go to an ADV rally please let us know...I think there are many here who would love to get your feedback in person. That would be fun.
