Astra (not that that matters?) tyre. It's fairly new and lots of tread but it slowly loses pressure over a couple of days. There is no obvious damage to the tread/sidewalls etc so I had it in the bath-it showed a couple of tiny bubbles in a couple of spots round the rim. The wheel doesnt appear to be damaged or bashed and bent, so my question is can the tyre be made good? Or will I have to get a new one? TIA frank
It won't be the tyre. It just isn't sealing to the rim properly. You want to get a tyre place to take it off, check the rim and brush it clean and refit it again. You could also put a can of tyreweld into it instead which would be cheaper.
frank ( snipped-for-privacy@lakehome.freeserve.co.uk) gurgled happily, sounding much like they were saying :
Steel or alloy wheel?
Tyre'll be fine - unless you run the car on it underinflated (or get caught by the missus putting it in the bath) It just needs re-sealing on the bead.
It'd make it a bit messy for next time the tyre does come off and also screw up the wheel balance. If you want to be really cheap you can unmount and remount a tyre at home.
Get tyre taken off rim. Grind all the s**te off the rim around where the bead seals and have the tyre refitted using bead sealer.
If it's an alloy wheel, refurbishing it will solve the problem. I had terrible pressure loss in 3 of 4 alloy wheels, and now they stay the same for months. It's corrosion around the bead seat.
I assume ill need more than mams tablespoons to get it off the rim?

I've changed car tyres in the dim, distant past using decent motorcycle tyre levers. To break the seal to the bead I put the wheel under a car, and used a hydraulic bottle jack.
I would have to be bloody desperate to try it now, especially with a low profile tyre!

He doesn't need to remove the tyre so all that is needed is to push the tyre off the rim, using a press or other method. You really need a compressor to get the tyre back on the rim as I doubt a footpump would work fast enough. Lighter fluid is fast but can't say I've tried it.
I've reinflated them in the past with a footpump by the time-honoured method of tying a rope around the centre of the tread.

It could be a nail in the tyre, that will also produce a slow puncture. It has happened to me twice after visiting a well known DIY store. I observed the loss in tyre pressure over 24 hours, then could extrapolate back to the exact time when I had parked at the DIY store. Presumably, some bits that were dropped from a builder's van.
A nail in the tread will be causing air bubbles to leak from the rim how exactly? Perhaps you need to read the OP's post again.
