I've always used specialized tires tubeless and have been able to get the bead to seat with a normal pump. I get a new Maxxis, pump won't get it to seat. Put in a couple little red cups of stans, pump my ass out (say what?) Won't seat. Drive to gas station, and with use of the Shrader to Presta adapter, it seats and inflates and holds air. Leave it overnight…still holds air. But I'm a bit paranoid as I believe half of the stans I put in was lost in the original shit show of trying to get it to seat at home and enroute to the gas station. So I deflate, break bead open enough to dump in another red cup of stans. Pump my ass out again (say what??) Bead won't seat. Air and stans flying out everywhere. So I just hose theh shit out of everythinig (yard, rim, tire) and use a tube.
I guess the lesson here is:
1. Maxxis EXO TR are harder to mount than Specialized.
2. My home MEC pump isn't what it used to be.
3. I should have done the whole damn process at the gas station.
4. I'm an idiot.
Thanks for listening.
