Tyres losing pressure
A couple of the tyres on our alloys keep slowly losing pressure. The local tyre depot said its rim corrosion and a common Mazda problem. They removed the tyres, cleaned the sh1t off from round the rims, smeared anti corrosion grease round and re-fitted.
Unfortunately the problem hasn't gone away. What's my next step? Can I get the wheels more extensively treated or are they knackered?

Re: Tyres losing pressure
Not a Mazda problem but a wheel problem surely? Are they steel or alloy? My alloys were a bit like that until i had them restored and powder coated and new tyres at the same time. Surprisingly cost effective and the air loss problem vanishedbrianjeff50 wrote: ↑Sat Sep 08, 2018 8:58 am A couple of the tyres on our alloys keep slowly losing pressure.

Re: Tyres losing pressure
Alloy wheels degrade and become porous and or corrode allowing air to escape the only way to resolve the issue is to have them refurbished or you could try a nitrogen fill as this apparently has bigger molecules which permeate more slowly?!
I had mine refurbed end of last year in anthracite, as the one's on my van were in a truly awful state yet the bodywork and chassis is absolutely mint, perhaps as the garage has indicated Mazda have a bad rep for alloy wheel finish and longevity.

If your tyres are in good nick you could simply fit tubes.teenmal wrote: ↑Sat Sep 08, 2018 11:05 am Worth a try...…..

Re: Tyres losing pressure
Out of interest which wheels are Mazda alloys? Is it those 15" 5 spoke ones? There seem to be a lot of different types fitted (mine are jap fitted aftermarket Precious diamond cut 17" alloys, and they also got a bit leaky with age, now cured it seems by refurb and powder coating). I'm wondering if maybe the tyre fitters are making it up as they go along?Flanners wrote: ↑Sat Sep 08, 2018 4:14 pm Alloy wheels degrade and become porous and or corrode allowing air to escape the only way to resolve the issue is to have them refurbished or you could try a nitrogen fill as this apparently has bigger molecules which permeate more slowly?!

Re: Tyres losing pressure
Yes they are the Mazda ones - pretty messy inside when he stripped the tyres off. Sounds like a refurb is in order - unless I just revert to steels.

My van is the Aero and has the wheels like this pic: https://www.google.co.uk/search?q=bongo ... kP0e2mD2RM:mikeonb4c wrote: ↑Sat Sep 08, 2018 7:10 pmOut of interest which wheels are Mazda alloys?

Re: Tyres losing pressure
Link seems to be showing lots of pics but think i know the ones you mean. I reckon a refurb/recoat might be on the cards. Wonder what singles out Mazda alloys as poor

Re: Tyres losing pressure
Hi,
Not uncommon problem with all brands of motors with all brands of alloys. Had this pronblem with many alloy wheeles over the years as they've got older & corrossion has set in. Whenever I have my tyres changed I ask for them to ensure that the rims are cleaned well & that the more heavy heavy duty rim sealant used when the new tyres are fitted. I have used the same tyre depot Dexell Tyres for longer than I can remember & have built up a good relationship with the staff. when I first had the issue of air loss due to leaky rims. I noticed that when I went back to the van the rims had a thicker pink residue arount the tyre bead. When I pointed out that it looked different to the usual stuff you see left around the tyre. I was told that it was a product they use to help seal rims if they know there is likely to be problematic. So I always ask if they would kindly use that when I have tyres fitted. It has reduced the problem for me , but ultimatly its a refurb that is usually the fix all.
Cheers
