Hi all,

     Are the standard NA wheels known to go porous?

 

I have a slow puncture at the rear. I took it to a place to fix the tyre - they did something but the slow puncture remains.

 

I guess if I had a large enough container I could submerge it and look for bubbles. Or I could just get a new tyre, but I was wondering if it could be the wheel itself - or if that would be very unusual?

Not to the best of my knowledge.
I've had the wheels as long as i've had the car - 10 years - , had two sets of tyres, and not had issues.
Granted my wheels are the anthractite and not silver but I can't imagine the paint makes a difference, unless it's thicker and masks porosity.

I'd be looking at the rubber of the valve body or the cores in the valves first, unless they were changed by the tyre place.
Check the tightness of the cores. Or replace the cores to get new o rings.
After that i'd still be looking at the tyre before porosity.

Are the rims clean where the tyre bead fits ?
Hairline crack in the wheel?
Valve and core should be changed on tyre fitting so shouldn't be that
Not much it can be really

Thanks both. I'll have a good look at the valve. I forgot that you could change valve cores relatively easily, I'll have a go at that and have a look around the bead seat.
