Hiya, I bought my Panda a month ago, its only got 23000 on the clock, and its two years old.
Have just noticed that all my tyres keep slowly losing pressure, when I went to check them one was sitting at 10psi. Any idea on what could be causing the problem? It's only wheel trims that are on, and they are the standard ones that came with the car, and its still got its original tyres too.
I would understand if it was just the one then, it might of been a puncture, but all four are slowly going down - though one more than the others.

Thanks for your help

Have you noticed (apart from the tyre pressure) any unusual wear on the tread?

If it is the original tyres they might be starting to degrade, plus most tyres lose presure.

How often u checking them???

Personally, I'd be getting the valves checked. Had this on a previous car where I had a new tyre fitted and it just wouldn't hold pressure. Tyre place replace/reseated the valve and all was well.

If you suspect a puncture, you could try the classic technique of inflating the tyre, removing the wheel and dipping it in a puddle or bucket etc and roll the tyre all the way round, if there's a puncture you'll see little bubbles emerging however it's not the best/safest technique and if it's a slow puncture you could be there a while.

It will be valves or that the tyres were poorly seated onto the rims. So a solution may be to get the tyres reseated on the rims and check the valves when you are at it.

Obviously check for punctures.

The tread on the tyres are all fine and legal. I never checked the pressure until I had the car for three weeks, and now I'm doing it every three/four days just to be on the safe side.
There is one going down a lot more than the rest which I'm thinking is a slow puncture, but the rest seem to be slowly losing pressure.
Will check everything you've suggested, Thanks for all the help so far guys - much appriciated

As trackdayqueen says it'll be the valves or the beads leaking, especially if all four are going down. You may well have a puncture too in the one that's going down quicker.

Almost certainly due to external temperature changes - hot weather makes the wheel expand in the day, then contract in the cool night period - and loss of bead seal. Advice astrackydayqueen above - have you got it sorted then?
