Tire going flat - thoughts?

[MikeG]

SO last week I took the rim and tire to the local dealer and had them remount it with a new tube. THe tech has decades of experience and said everything looked fine. He said there was a pinhole leak in the tube but that there was no corresponding tire damage.

I rode 25 miles last week and 60 miles yesterday. I went out last night to take my gf to see a show and the tire was super low again.

This is really p!@@##g me off, I was supposed to be riding with a group today and now I won't be able to make it. Of course there are no service places open on Sundays

fill it up and monitor it at all your stops

Same recurring issue with a trail 90. I purchased a rubber band designed/sized to the diameter and width of the rim. The PO had wraps of duct tape that apparently failed after 30 years. So I don't actually know the cause, but I got the cure and that cabin bike sits all year, gets no highway miles and overloaded when used.

Ditch the tube & fix whatever is leaking, tire, valve, or wheel. A tube may stop the air from coming out, but it won't fix the original problem. Rekon why most all modern tires, except on spoked wheels, are tubeless, just my opinion, the tubes are more trouble than they are worth.

im pretty sure his are spoked

You could have just been really unlucky, and the fitter did not check the tyre properly for anything sticking through. A thorn projecting 25 thou into the carcass can cause this.
Is the rim rusty? A flake of rust could do this, and may even stay in the tyre and get "refitted" with the new tube, or maybe he just pinched the tube on the way in.

One thing for sure, it will only get worse, so do not attempt to ride on it.

Remove the wheel, pump it up to 50 psi, then put the whole rim upright in a trough of water, deep enough so water covers the tyre and a few spoke holes. Turn it round bit by bit until you see the bubbles.

Mark the place (on tyre and rim) and you know where to examine minutely when you remove the tyre.

Throw the tube, don't repair it.

The fitter has 15 years experience at the Harley dealership, he took his time and did a good job. I'm going to bring the wheel back some night this week along with my spare and he's going to make it right.
