Have had a problem with the nearside rear tyre losing pressure over about 2 weeks. Had the tyre replaced as it was end of its life anyway and the new trye is doing exactly the same. I suspect there maybe something wrong with the alloy wheel. HAs anyone every experienced this and also would this be covered by Skoda warranty. I have not kerbed the wheel at all it looks a1 from the outside.

If the wheel is under 3 years old and the one fitted to your car then I'd be paying the dealer a visit.

They will most likely be able to take the tyre off and see if the alloy has any gaps etc in it or any damage. If it is damaged and caused by bad fitting you can go after the fitter.

If it is a warranty job they will deal with it and if neither, do you really want to be driving around with a dodgy tyre?

I had exactly the same on a Passat about 4 years ago. Tyre was losing about 2psi per week. I had the tyre removed and refitted by a tyre specialist who could find no problem. They inflated the tyre to 60psi and tested it in a water bath with no result. They suggested a porous alloy wheel and that an air loss would not show up; cracks or holes in the alloy would be too small to see but could still let air out over a period of time.

To be fair the VW dealer then replaced the wheel under warranty with no fuss and the problem was solved (still using the original tyre).

I too have had this issue, over the last couple of months with the nearside rear tyre needing pumped up approx every two or so weeks. i have noticed that with the colder weather that i seems to require pumping up less often.

I had originally thought it was a slow puncture but the infrequency of the tyre needing pumped up made me think other wise.

My first alloys were on a 1995 Xantia that I had from new. No problem at first but after a few years I experienced pressure loss like a slow puncture on (as I remember) most wheels.

Turned out to be the protective lacquer inside the rim gets damaged when tyres are changed.

The damage is where the tyre bead seals against the rim. After a time corrosion occurs in the form of white rust which pushes the tyre away from the rim and a very slow leak appears. I guess that air seeps out all round the rim so not easy to detect by submersing in water.
