Leaking tyre valve - easy fix?

[Benjaminpalma]

I decided to check my tyres today. They were a little low, so I pumped them up. The valve on one of them started to leak as soon as I took the pump off.

Waterproof grease applied the inside of the metal valve cap should slow the leak (the valve caps also have grub screws to keep them in place).

Is there an obvious cause for this, and an easy fix?

Thanks.

the valve core will unscrew just try nipping it up

Thanks.

Not sure what nipping up is, but would a pair of long-nosed or circlip pliers be sufficient to get in there and unscrew the valve itself? Or would this damage the inside of the valve body?

should be OK don't over tighten, you will see if its loose
bike puncture repair kits sometimes have the correct tool

Google "tyre valve key"

Thanks very much, guys!

Looks like a trip to Halfrauds is on the cards, now that I'm starting to get my head around tyre valves...

I imagine I'll need to jack the car up and deflate the tyre fully before working on it...

I don't see that you need to do that, if you have the key try tightening up first, then check the pressure if the value is broken just unscrew and replace then pump up the tyre again

Or a little cheaper than Halfords (no surprise)....... clicky

Thanks for that! I just got the bits from Halfrauds today. Will give it a whirl tomorrow...

I would at least support the car if you need to take it out... don't want to break the seal on the trye to the alloy... BTW... how do you intend to re-inflate?.. got a pump??

Thanks. Yes - I was going to jack the car up to take the weight off. I only need to deflate so as the valve doesn't pop out into my face (I think!). I've got an electric air pump all ready...
