"leaking" alloy wheels?

Do alloy wheels "leak" air?



I've never had the "luxury" (?!) of having alloy wheels on a car before and have found that I have to keep topping up the air in all 4 tyres every few days.



At first I thought it was the airline at the local garage being out of calibration, but after using several different garages, I have the same symptoms.



It normally only drops 2-4 bar, but on one occassion it had dropped by



10bar which made for an interesting drive!

The weather has been very changeable of late here in the frozen North, but I wouldn't have expected such a dramatic drop in tyre pressure.

Is it a new car or old car?

It's almost certainly either a poor seal on the bead or - if the alloys are old - corrosion leading to them being porous. The only solution is to take the tyres off and get the wheels sealed.

Dropped by TEN BAR?

Normal tyre pressures's only 2-3bar...

Ah....you spotted my deliberate mistake!!

Silly me, of course I mean psi.

Anyhoo, the wheels are the originals (1998) and the tyres were only fitted in January, 3 weeks before I bought the car.

My money's on the beads then.

Should be quick, easy and cheap to sort.

Where do I go to get this kind of work done?

Is it a specialist job, or do I go along to Kwik Fit?

Actually, if I have to go to kwik Fit, I'll pass- don't rate the local branch too highly................but that's another story

Any local tyre place. There's others than K-F, y'know... Just have a look in the Yellow Pages, and ring a few of the back street ones - they'll probably do a far better job cheaper.

Wise move...

Thanks for the advice.

There are plenty of other companies in my area, K-F were the first ones to spring to mind when I was writing.

If you're likely to want the tyres repairing, it is. Otherwise an aerosol of sticky usually works.

Sorry to go off thread but do you pronounce your surname Dee -al? (like the fictional TV Copper!)

"D.L.", you mean. Yes. Why would I pronounce it wrongly?

I know a couple who insist on it pronounced Dal Zeal.

I would've thought 2-4 psi quite possible due to temperature changes, but then you're only seeing drops and never rises? Alloys shouldn't leak any more than steel provided there's not corrosion round the seal area. Could've been a batch of defective valves fitted?

Gladly. :-)

On the other hand, they are ministers, so would probably have God on their side....

I had the same problem and the only real cure was to have the wheels refurbished, which cost around 100 quid and they made a super job. the tyre places just wire brushed the bead area which inproved it but never cured it. Other than that you could always fit inner tubes bit old fashioned but it will work! Rob

That's quite possibly the most dangerous piece of advice I've seen posted to Usenet in quite a long time.

Ah, but I have Wikipedia...

's not a zed, it's a yogh. Apparently.

Depends if you're a normal person or trying to be a trendy.

It's like the BBC news readers who now pronounce the country Niger in a french stylee.

It's hardly a battle of the giants...

I've had that on older cars. Alloys are a pain. Have someone take the tires off and then clean the rims with a power wire blush. Then lacquer the rims. It can't be done in 5 minutes as the lacquer has to dry properly before the tyres can be replaced. 10 pounds per tyre.

You could also try some of this tyre sealant stuff. You deflate the tyre, remove valve then inject the sealant liquid which stops punctures should they occur. Replace the valve and reinflate with an air line. It should seal the leaks. Should work out cheaper than having someone lacquer the rims and you won't get punctures!
