Loss of tyre pressure

[Kithmo]

I'd replace the valve core. Tyre fitters usually unscrew them when they deflate the tube or tyre, they may not have tightened it back up enough or it could be bent.

Gerd, I run tubes in radial tyres on wire wheels. The inner surface of most radial tyres is not designed for a tube and can abrade the tube to the point where they are no longer airtight. However and whatever the reason for air loss a new inner tube will only cost you about £10.00 or €12.00, should you decide to stick with tubes. End of problem and so
A HAPPY NEW YEAR.

My guess would be a valve - I've just taken my Discovery for an MOT and was told that the valve was perishing, so they changed it. More crap rubber from the far east ! That may be why I've had two trailer tyres burst on me when pumping up to the proper pressure. If the car and therefore the tyres don't get used very much they aren't changed very often, so perishing is much more likely to be an issue than in everyday cars.

Let us know what the eventual diagnosis was then we are all better off.

Probably not related to this particular issue but I once had a problem with tubeless tyres on my TR which with wire wheels needed inner tubes regardless.

One by one the tubes were letting go, Finally we determined that there were some small stickers on the INSIDE of the tyres, production numbers I would guess. The glue from them was seeping out and eating up the inner tubes. I now always insist on all of those labels being removed and the glue residue cleaned off..

Just to finish this thread: the problem seems to be solved, by swapping to a new tube.
Thank you for your advice.
