VW T5 tyres losing air - worth getting new alloys?

[CliveM]

I've got an irritating problem with my camper van. One tyre in particular - but all of them do it to some degree - loses pressure over the course of 2/3 days.
They're van tyres running at 48-54psi.

The tyres themselves have been replaced because they were worn. Is it worth looking for new alloys (mine are pretty corroded - but it's not a showboating van, it gets used) just to try to cure this?

Anything else I should try first?

Other option is to get the tyres taken off & the gunge that tyre fitters use painted on, or get the wheels refurbed.

I'd get the wheels refurbed, it'll improve the looks and sort the leakage.

I had a set of ferociously porous alloys on an Alfa in the 80s. Solved it by stripping the tyres off and painting the insides of the rims with a thick coat of Smoothrite to seal them.

Job jobbed.

Corrodoed wheels may well leak a little, but worth checking that they aren't cracked at all, that can cause a leak but means the wheel is junk really,
If it's just corroded her the worst one refurbed and I bet it fixes the problem. You could just take it to a tyre place and see if they can add some sealant to the rim before putting the tyre on.

I'd originally looked at refurbing the alloys but then thought it might not cost any more to just buy another set?
Or is there a drive in / drive out sort of place for refurbs?

I'll ask - cheers

OK - so I got the alloys replaced with a set of Wolfrace alloys.

One tyre is still deflating - not spectacularly but it goes flat over the course of a week or so.

Is tyre filling foam an answer? Anyone got any experience of using this stuff and any recommendations?

I've had problems with one Tyre having a slow puncture. I'd put it down to little git over the road taking exception to me & dog chasing their peeing Tom cat out of garden as for weeks tyre would hold normal pressure, then overnight go down . Today, I changed the pair, and inside of alloy was manky(enough for fitter to suggest that this was source). But if new alloys, then perhaps time to try some gunk.But be aware that if you get a puncture, then it may cause problems to tyre repair process. ( Leastways ,that what the can of gunk says)
