Here's a funny thing! (1 Viewer)

I replaced all of my Tyres on my Hymer due to cracking and also failing to stay up at the correct pressure. I changed from Michelins to Continental Camper tyres. I'm happy with the Continentals, but I am still having an issue with the Tyres losing pressure gradually. On my Hymer I have got Goldsmicht Alloys and I am wondering whether therein lies the problem. Does anyone think that the alloys may not be creating a perfect seal and therefore losing pressure over a couple of weeks? No issue really as I now have a new tyre inflator which inflates in minutes, but a bit of a b--- ache having to do this so regularly!

Any advice helpful, maybe this is normal with a heavy Motorhome sitting on the tyres. What does anyone think?

Have you tried spraying the wheels with a leak detector spray, might find your issues?

 

[Otter Spotter]

If there appears to be any pitting on your alloys either around the rim or on the spokes, it may be worth finding a quality restorer who will sort them for you

Alloys nearly always leak after a while, they can be a pain at times.

As Borderland says, alloys do tend to leak.... a lot ...
Most usual culprit is they are a little porous
Quick and dirty method is to inject some of that god awful anti-puncture crap.. not something I would recommend but it would work
Another answer would be to have the tyres filled with nitrogen
Nitrogen molecules are larger that those associated with normal air and tend not to leak.. Often used by bikers

But the correct answer is to have the tyres removed, the wheels carefully re-prep'd on the bead seats, and then sprayed with a ceramic coating

But chances are who ever fitted the tyres did a bit of a slipshod job of cleaning any and all corrosion on the bead seats

I was going to suggest nitrogen if you think the tyres are fitted correctly.

Had this problem on my 2003 Seat Arosa, had them reseated with gunge a couple of times, didn't make much difference so had all 4 refurbished at great cost.. Couple of years later 2 of them start going down again.
Got second hand steel wheels for it now and it's been alright since

Did they replace the valves? Prime leakage area

 

[Jugster]

Yes all valves renewed. Fitted by Kwik fit. Will try and get them reseated sometime. Not a real problem at the moment, just a bit anoying.
