Filtered valve core needed for Dyna beads?

Hi guys,

I'm going to switch to Dyna beads for my next set of tires. Does anyone know if the filtered valve core is required or recommended on cycle tires?

I've got ghetto Dyna Beads (air soft pelets, and lots of em) on my winter beater Ford Ranger. No filtered valve stem on there.

Re: Filtered valve core needed for Dyna beads?

I have used Dyna Beads for two years and haven't used filtered valve cores. But on one occasion a bead got stuck in the valve core and wouldn't come out, so I lost all the air out of the tire. I was at home at the time, so I just put a new core in. Now I carry spare valve cores on the bike and a core tool.

Problem with filtered cores, they don't come in lengths we can use on bikes, IIRC. If I could get some that would work, I would definitely use them.

Re: Filtered valve core needed for Dyna beads?

You don't need the filters, but it is a good idea to put a blast of air through the stem before you check the pressure. It's also a good idea to have the stem positioned between 6 o'clock and 8 o'clock before you check pressure.

If you add them right after you mount a tire, check to make sure there isn't any condensation in the valve stem. The last time I added them, I had just mounted the tire, pressurized it to seat the beads, and let the air out to install the beads. They would NOT go in, no matter what I did. I thought about it for a bit, and sure enough, there was water in the stem from the air escaping. I dried it up with a paper towel, and everything went much smoother.

Dyna Beads.... love 'me. Been using them in the Bandit for tens of thousands of miles and now on the SV. My tires wear better with no obvious cupping or scalloping.... they work.

Re: Filtered valve core needed for Dyna beads?

2Zukis do you reuse yours? I am gonna be mounting a new set of tires and I am not sure whether I should try and save the ones in my current tires.

I reuse mine. Some of them get covered in rubber, but they still work. I've recycled mine several times. You always end up spilling some when you change tires, but you get at least 85 to 95% back out of the old tire.

Re: Filtered valve core needed for Dyna beads?

I know this isn't helpful, but I need to say it. Dyna beads are dumb and I don't approve of their use.

I thought I was the only cheapskate around here. I used some #9 birdshot from a gun shop.


Not sure you need a filtered valve stem for any application. Think about it; what are the chances of getting a bead into the stem? Ypu'd have to be letting out air with the valve as the very lowest point. (pretty much impossible to do)
