I'am new to running tubeless, so I don't know much. But I'm running Stanz ZTR Flow Ex with Maxxis Minion DHR II tires on my 2011 demo. I have had the tire burp off twice now on the rear wheel, one going through rock garden and another in a berm. I am running the proper amount of sealant suggested, but its still burping off the wheel. Any advice to prevent this would be helpful, i was also thinking about just going back to tubes.

Likely low pressure. I had no problems at the park on the 29er running flow ex rims and continentals.

To determine a starting tire pressure when running NoTubes tires with our ZTR rim use this simple formula.

Rider Weight in pounds divided by 7 = x

x - 1 = Front tire pressure in PSI

x + 2 = Rear tire pressure in PSI

Example: 185lb rider

185/7 = 26.4

Front tire pressure: 26 - 1 = 25 PSI

Rear tire pressure: 26 + 2 = 28 PSI

thanks, I will give that a shot, but I had just put air in the tire before riding and it still came of the wheel.

I would like to know if the TR version is more likely to stay in place. My Conti Trail king Pro is usually wet around the rear bead after a hard ride. I certainly do not want to go from bad to worse.

Do you know what pressure you were running?

No idea, I need to buy a pressure gauge

Yeh, that was kinda my point, 26psi in mine and they feel rock hard, could never get em right without a gauge.

Seems like no matter what you are going to have a tire burp unless you are riding rock hard tires. If im at the park ill start the day off with a hard tire and by lunch i have to put more air in. Worst I ever had it was during a race run by the time i got to the bottom the tire was pretty bouncy.

Seems the stiffer the sidewall the easier the tire will burp, but thats a fair trade off vs ripping a tire instantly.

Depends on casing as well as far as what pressure feels like. I run about 30/32 front/rear on DHF's on my trail and downhill bike, but the trail is EXO and DH is dual ply. The DH tires "feel" much stiffer in corners and like they are higher pressure because of the tire casing.
