Frequent air level dropping of tires

[sltcdma]

I have a problem with left hand side of the tires of my car. Frequently the air level is dropping. First this was happend left-front wheel, when I checked the tire (alloy wheel) with U_H wheel at Malay Street. Tire shop guy told me there is a leak between the edges of the tire and rim. The alloy wheel was given some kind of repair by them and OK for about two weeks. However once again the problem is there. Rear-left alloy wheel also now have the same problem. When I checked for possible “patches” in the tires, they were ok.

 

Can anyone help me please.  Thanks.

Obviously there is a leak somewhere. 

From the photos, it looks like your rims are in pretty bad shape (not just the oxidisation, but it looks like you have some damage as well). My guess is that you have oxidisation build up in the edge of the rim. Assuming this is where the leak is, It needs to be cleaned up and a good sealer needs to be applied.

Define "frequent air level dropping". 

How many psi does it drop in one day?

How old your tiers are? Check for manufactured year and month. No matter you used or not tires, but rubber starts to degrade after some time.

How old your tire valves are? Press the valves from your finger to different sides and make sure quality of rubber valve is ok.

I suspect the Valve in the 1st instance as Sampath mentioned!

By chance if that Alloy is bent, you could expect the same.

Once this happened to my iron rims.

Pls do let us know the rectifications.

Thanks Davy,

As you mentioned front-left rim was repaired due to bad edge. Can you recommend me a good place to oxidization cleaning and sealing the edges. Hope it will bring my rims shiny look.

Thanks for your interest.

Not per day. once the air level is ok, it starts to dropping.

From a safety point, why not consider installing inner tubes on your rims?

Thanks. Valves are ok, will try to find out manufacturing dates.

Thanks. As I know my tires are tubeless, therefore can I still install inner tubes on my alloys?

[Twin Turbo]

Yes, without  the tubeless valves.

Hi All,

One of the alloy wheel in my Vitz has a small crack/hole and leaking air in a slow rate. Anyone knows a place to repair the alloy wheel using any method. The tires are ok, no punctures or anything.

@walkernetI haven't used either of the services personally but i believe Macro Autotech does

There's a small place called 'KBL Tech Welding' along the Rathmalana-Mirihana road in Pepiliyana near the Pepiliyana grounds. They did a decent job on one of my damaged alloy wheels 2.5 years ago and it's still well intact. You might wanna try that place if you are around colombo. There location is available in Google Maps.

Was about to recommend this place. They did a proper job on an aluminum sump repair for me.
