Tire burping on tubeless

I have had a few episodes of tire burping on my mountainbike tires with a tubeless set up. These have occurred when I have been running low pressure while taking aggressive turns where there was some tire squirm.

Would having higher pressure prevented these burping episodes?

a lot of this depends on what tire/rim combo you are using...so it is hard to say without knowing

i had crazy burping problems with enve rims and any schwalbe tire...higher pressure helped marginally, but i still managed to burp em...but mostly happened coming off drops and not cornering

i finally went with WTB tires with an UST bead. haven't burped since. they were a b!tch to get on the rim though. i could get the schwalbe tires on w/o levers.

Interesting, not the burping but the mounting issue. I've got enve rims and almost couldn't get schwalbe tires on the them but WTB bronsons went on without levers.

If you need a tighter seal between the tire and rim you can try adding another layer or two of Stan's tape.

How tight does the tire fit when you install?

Sometimes as the tires age they get a bit stretched out and more prone to burping. A year old tire will burp easier than a brand new one. Burping alone is not too big a problem, but if you burp one flat it can be a pretty big deal. Carry a tube. Ride gently.

Riding with 25 psi and the front tire burped when I leaned hard. I felt the squirm before the burp sound.

I only ride tubeless on my road bikes (no mountain bikes in my stable, right now). The only time a front wheel burped, I added a few psi and the issue resolved itself.

It should not burp at 25 psi. Add some more tape or try different tires. Are your wheels or tires tubeless ready? Converted? UST?

Yep, and help to protect your rims as well.

What rims/tires?

FWIW, I'm 160 lbs and run mine at 17 psi front, 20 psi rear. 2.35 Nobby Nics and 2.25 Racing Ralphs on Pacenti's TL28 rims. Never burped a tire, the bead seal is TIGHT.

Go tubular, only burping is from the rider.
