Tyre valve stem leak

[Burnerman]

I have to say that Laser tool is quite natty!
It maybe not quite as straightforward on a thick alloy rim but there's nothing to stop you trying!

My last post on the subject. If you have a new valve in an alloy rim and it’s leaking, it’s not the valve that will be the problem and changing it won’t solve anything. You need to be able to clean the corrosion before fitting a new valve and you can’t do that without breaking the bead. Do not use washing up liquid as a lubricant otherwise you will be back to square 1 in a few months.

Post in thread 'Puncture repairs'

4 Jun 2025

Went to go out on my old scooter this morning, flat back tyre. Pumped it up and had a Quick Look, thought I saw the tip of a nail in the tread centre. On my way home, I popped into a tyre fitting shop. It’s not as quick or easy doing a bike puncture compared to a car. The principle is the same but you can’t get the wheel off with 4/5 nuts, you have to strip stuff off. On my bike you have to remove the exhaust, a shock absorber, the brake caliper and one half of the rear suspension swing arm. I asked the shop if they could do a proper plug/patch repair if I brought the wheel up to them...

However, if you just want to make this into a multi page thread complete with arguments, refusal to accept advice and no solution or report on how it actually panned out, carry on, I’m out.

Are you though?

Absolutely. You’re not though. Any advice at all for the OP?

Change the engine oil and filter!

Seems you're not out afterall. In answer to your question, no I have no advice for the OP, none at all. Do you?

OK, you are starting after you have stopped. You do stuff in a funny kind of way.

I can only take you seriously if you accept a proper argument first. Would you like a 5 minute argument or a 15 minute one?

I don't understand why people keep saying this is their last post, when it really never is.

OK, an F-clamp is good enough to open a breach on my play tyre: 215x45R17. The clamp is just big enough to do my target tyre: 225x40R18.

Deduction: a second F-clamp (that I don't have) can ride on the breach to open it some more. Unclamping and reusing the first clamp will allow me to clamp inside the breach, eventually leading to breaking the bead.

Tomorrow: I will insert plastic wedges into the breech, then release the clamp and clamp on the thick end of the wedges. Theoretically, the sharp end of the wedges will break the bead.

I don’t think OP was ever after a solution , just wanted to prove the accuracy of his title .

You mean, like, I deliberately wanted a leak and have nothing better to do?

No, you're a Nutjob and a highly successful one too.

Not like.Any sane person would simply return to tyre shop for a free repair .

But, I am looking for a lifetime free repair, though. I like everything to be life time. If it wasn't for the shop, I wouldn't be here. You think I should go back for more?
