Is this a common problem?

[BriTXbike]

When I had my new set of tires put on my bike about a month ago at the dealership they had to keep it another day, close to closing time when I took it, b/c he said the front tire would not seat and they needed to acid treat the inside of the rim for corrosion and pitting. They said it's a common issue with older bikes. It was hard not taking offense to that but I obliged. Now the tire on it and it will hold air but about every two weeks I have to add about 15 pounds to get her back up to spec.

Anybody else have this kind of problem?

I've never had this problem. If a rim looked rough or pitted, I've cleaned them up a little with a steel brush before mounting the tire. Never because of a problem, always to keep from having one. Have you found the leak for sure, Possibly a valve stem leak or a flaw or small crack in wheel.

Spray the tire with a soapy mixture like 409 and see where the bubbles come from. Might be a defective tire, I have see one leak through the tread on a friends bike.

Bead leakers

Part of my job is running the tire shop for a small vehicle fleet and I can say that tires that leak around the bead are no fun at all. If it was my bike I would want to know where it's leaking and why. If the shop told me what they told you, I would ask to see the pitting before they did any etch to it. In my experience with car rims I can recall only once in 10 years where we had a leaky bead on an aluminum rim. Usually it's a steel rim that has rusted (the inside of a tubless tire is a damp place since compressed air almost always has moisture in it) and has pits in it. Now, having said all that, there is a product out there that is a bead sealer. It's like a heavier adhesive that you liberally apply to the bead before mounting the tire. It would seem that this might be your next option. I know the company that makes the kind we use at the shop has a web site. I will try to remember to get the company name and post that but I don't plan on being in the shop til monday. Now that I sit here and think, I think the name of the company is Safety Seal. I'll check. Either way, I would get it fixed. A tire that goes flat is a safety hazard on a bike. And it probably will get worse before it gets better.

Oh, also check that your valve core is not the leaky culprit. It may be that simple.

I don't use it but with the slow leak Maybe use a smalll amount of tire sealer. The other option would be to put a tube in it
