Fitted wheel with new tyre, sound like stones in it?

[Eddieb]

so

Got a new tyre fitted to my front rim a few days ago, took the rim off the bike and dropped it into the shop saturday morning and picked it up with new tyre fitted Monday afternoon.

I fitted the rim back on the bike this evening and if you give it a spin it sounds like there are stones in it and if you stop the tyre with your hand you can hear and feel things rattling to the bottom of the tyre.

The rim is tubeless but had a tube fitted when I dropped it off, I can't see how it would have anything rattling around in it if a tube was still fitted.

Thoughts and comments?

I'm thinking of popping into the shop tomorrow morning to see what they have to say.

hell yes take it straight back and make em listen !

Are your spokes all intact? (if you have em)
The shop might have lost a tool.
Time is very quickly running out... the big day looms

Dumb question, but does it have those weight things on the spokes. Mine come loose every now or then, and at slow speeds, they click as they slide up and down the spoke. It's pretty cool. Like kiddies with clicker things on pushbike spokes.

ask if any of the mechanics have lost their keys

Thanks guys. No Bart, no spokie dokies or bits of margarine container pegged to the spokes.

I have a cheap tube (cheng shin or vee rubber) and there is now a small ball of rubber loose inside it - wasn't like that when new. Possibly all the loose bits inside the tube have clumped together or something. Never noticed this with a jap/euro tube.

They beaded the tire?

O.k, never heard of this happening before. from memory the tube I had in there was a heavy duty Vee Rubber. It sounds like there are 2 or 3 of whatever it is in there.

I had the same happen with a 'spensive Bridgestone heavy duty one. Weird, eh?

So I took the bike back to the shop and got them to have a look. The tube was in the rim and whatever was making the noise was inside the tube.

Neither the guys in the workshop or I had seen anything like it so not wanting to have it fail unexpectedly I made the call to put another tube in the rim and we cut the old tube open to see what was going on.

Rubber balls?

Did you inspect the inside of the tube - any signs of a weakness or fault or anything of concern?

Couldn't see anything wrong with the tube, and I watched John install it in my garage just 2 weeks before. I'd had it a while but it was new out of the box.

And those 5 little balls are only about 1/4 of what was in there.

Eddie this is quite common on tubless tyres when they are removed for replacement they usually look like black rubber by then. In the manufacture of tires and tubes they use french chalk (like talcum powder) to stop the rubber sticking and make them move into place. I am picking that the air used to blow up your tire had a very high water content which mixed with the chalk has formed small powder balls they wouldn't have caused any problems. Workshop compressors that are used heaps at this time of the year produce alot of condensate in the tank and should be drained at least weekly if not more often most small workshops have very little air line filtration in there systems.
