Dyna Beads causing tire failure?

I've seen a few videos about folks using "Airsoft" pellets in their tires to achieve the same results, as a more affordable alternative.
Not promoting it by any means... Just tossing it out there. :oldsmile:

Knows some things
Well I'm going to bring up a dead horse, because I just ran into something I've never seen before. I even went back and looked at the several used tires I have laying around here. None of them show any wear on the inside of the tire.
@Forsaken stopped by on his way up from Florida, because he was having some high speed wobble. After checking the neck bearings and wheel bearings, I spun the tire and seen it had a broke belt in it. Tire date is 7715, and was put on two years ago, and has less the 2000 miles on it.
The first thing I saw when I took the tire off was powered rubber all over the rim, and looking inside the tire, you can see the ridges were all wore off the inside. And it had a big crack in it. He probably ran over something.
I don't believe the beads caused the tire problem, but was surprised at the loose rubber in it. Weighed the beads, and there was 2ozs.

That is interesting one of your pics looks like a slice on the inside of the tire?

Those wear marks are unusual almost like something was in there that shouldn't have been..like a much harder compound (metal). I know there are lots of companies out there making balance beads and some make them out of metal, glass, cermamic you name it.

With that said I have a front tire on my k9 dated 4914 so it's not even 3 years old and it's showing signs of aging. Granted it has 8k on it, but the tread is still 50%. I'm not sure what's up with the rubber these days.

That's unreal wear on the inside, I wonder if it was the beads or not? Avon tire? I do know the Avon's are quite a bit softer than some other tire companies. Maybe a bad tire from a bad batch or something. Next set I replace I might go with the new dual compound Michelin tires which are harder in the middle and softer on the sides. I ran those on some street bikes with good luck.

I looked a while back and don't think The Michelin Man made tires for our dogs.

The Avon bad batches were about 5-6 years ago I researched and made some calls before deciding to go with new avons when I go to Andrew Barnes this Friday also it was all sizes in Avon that was affected not just the 300
I sent him my bike in March, He's doing some upgrades and some PM, can't wait to get it back. He must be super busy these days and I will not bother him. Take a picture for me lol. Good luck with the new rims and tires.

Last winter I replaced tires on my K9 and put 1 oz of dyna beads in the front which is whats recommended on the dyna bead tire chart. It does bounce a little but just noticed some are running 2 oz in front. Is this what I should do?

Really there isn't a specified amount if you get correct on it, the shop that does mine, spins em on the balancer and whatever it calls for is what they put, re spin and it usually zeros out.

Yes you can try going up 1/2 ounce at a time until it balances out.

Check the tire pressure too. I notice I get a wheel hop at 60-65 if my tire pressure is a little low.

Makes sense. Since I dont have a shop close, I will try the 1/2 oz steps this weekend. Im pretty religious about correct psi before each ride so thats not the issue. Probably just not quite enough beads yet. Thanks guys!!!
