Just picked up a new Animal GLH tire which has a 110 psi rating and every time i start blowing it up, at around 68-70 psi the inner tube blows out. I've tried 3 tubes already and all of them blew out. Does anyone know why this might be happening?

Taht's weird that they keep popping at 70psi. Try using a tube from somewhere else and see if the problem persists

Your PSI gauge might be fucked, giving a lower reading?

either the tubes arent designed for that high psi, you arent seating them correctly, or they are just shit

Pump till solid and if it hasnt popped let it sit and the tire adjust to pressure being on it? I bought a brand new tire one time and went straight to 110 psi and blew out some of the bead and ruptured the tire on the middle of the tread after about a month. Im superstitious about some stuff though.

This too. Make sure that you don't twist the tube, Pinch it in anyway, the tire doesn't have a cord/thread showing from a defect or something &also be certain that there isn't anything sharp around the valve stem hole on the rim or on the rim in general.

might be a good idea to use an air compressor to blow out any debris still clinging onto the inside of the tire and rim

Or you may need a rim strip because your spokes and or nipples maybe puncturing your tube.

why would you need more than 60 psi anyway?

It sounds like the tire is not seated properly in the rim. Did you buy the tires from us? If so, next time just give us a call if you need help!

The most important part is to make sure the bead is fully seated in the rim. To do this, inflate your tire to around 10 PSI and then rock it back and forth on the rim to make sure it is seated properly. Inflate a little bit more and then repeat. If the bead has slipped out when you were inflating the tire, check it for damage. If it is torn you may need a new tire.

Make sure the bead of the tire is correctly positioned. I've blown out a few tubes because I beaded a tire wrong.

Ah I think thats it. Thanks a lot for the help. And no I bought it from Cyclepath Calgary. But have ordered stuff from you guys in the past. Great service, love your shop.

Inspect the tire bead, the rim and find where the tubes pop. That will help narrow down what they issue is. Then correct it. I would bet you pinched the tubes.

check to see if there is something in the tire and check the rimstrip for a hole.
something sharp is probably in there causing the puncture.
find out where the hole is and look at the corresponding area in the rim/tire.
hope this helps!

This.

I weigh 245 lbs give or take depending on if I pooped, and I run 80 MAX on the BMX. Usually I air em up once a month or so (I don't ride a lot these days).
