Do you tighten the nut on the valve stem on a inner tube? I've had 2 tires where the valve stem pulls out of the tube and I am wondering what I did wrong.

Only kind of valve stem I have seen that is threaded like you talk about isn't on tubes.

All the tubes I ran just had the valve stem stick out, but I did a google search and found this one that matches your description:

Since there are two nuts on it, I'd only assume one goes on the inside of the rim, and the other on the outside and tightened down.

I use those on bikes,yes you tighten them......Ive never had a tube last at all on our old 90.......just eats them...... I think tubes move around too much in the atv tires?

Describe your process for putting a tube in a tire and airing it up.
I've run tubes in various atv tires and never had a problem unless it was my fault.

I do bikes all the time without issue. Cant get my old 90 to keep a tube....always ripped at the valve stem....Like the tube is sliding around or something.Originally Posted by f76

Got the holeshot
I put a tube with a regular style valve stem in one of my 85 250r wheels . It has held up fine for years. I put a small hose clamp on the valve stem to hold it.

After you air up the tube and set the beads, do you leave it like that or let the air out of the tube and then refill to desired pressure? A tube shouldn't be "sliding around" inside the tire once air'd up.

I air up to seat and then let air out and bring back up to bout 8lbs......I do it the same as I do my motorcycles. It never has punctures, just ripping at the base of the stem.

Can you put a washer before the nut on the inside of the rim, then push through and put the second nut on from outside?

You can never have enough! ATC250ES is still the best!

I was talking to a guy at a tire shop and he said you take both nuts off but leave the angled washer on.

Catch me if you can
They tear because the tire spins on the rim and our air pressure is so low.
One of the best mechanics I met told me to leave the nut near the top and loose. When you see it angle over, empty the air and straighten it.
Tubes are useless.......

Awe you beat me to it, but completely agree. If the tire is old or has been ran flat and slipped enough to eat away at the bead, it would slip even after aired up. About the only fix is new tires or over inflate to the point they don't slip any more.

Agree on tire pressure- you are gonna have to run more than 8. If the tire is cracked on the outside then it's cracked on the inside and the tube could be getting pinched or spun. The way I do tubes is the washer then a nut then thru the rim then the second nut. Fill the tube till you have no sag in the side wall of the tire I'd go till its moderately hard.

When I was putting my YTM together I wanted to use the tires it came with, but the beads were mangled, so I bought tubes. The first set tore at the stem idling down the street, so I ordered $uper heavy duty tubes that cost more than half a new tire. They lasted about 10 seconds longer, so I bought new tires. I swear we used tubes without problems back in the day. I wonder if the tubes were better reinforced back then for low pressure tires??

.
They make standard and heavy duty [thicker] tubes for many apps . . The heavy duty ones cost more but are far less likely to do that . . I used heavy duty tubes on all my bikes when I raced Motocross and Desert to reduce the chance of the valve stem pulling out of the tube . . I also did not install a nut on the outside of the bikes that had tires slip on the rims . . This greatly reduced the force on the valve stem, and once the tire had slipped far enough, I would simply let the air out then rotate it so the stem was pointing slightly forward of 90 degrees to the rim opposite of the direction to tire would slip in to allow for a little more tire slip before I had to re-position the tire.
In addition to using a heavy duty tube if you can get one, you can try an old school racers trick of putting baby powder on the inside of the tire and on the tube . . This reduces the pulling forces the tire has on the tube because it allows the tube to slip more freely inside the tire . . You could also try not using the nut on the valve stem.
