Hi

I need to keep inflating my 2 front tyres every couple of days
They don't have a puncture as they have been replaced and this has been an issue for a while now

Any ideas?


Thank you

My first guess is faulty valves. If not, have they been installed properly.........ie, are they close fitting on the rims ?
Yes a leaky valve. Did you replace the valve when you changed the tyres?
Eddie....wouldn't most tyre fitters have automatically put new valves onto the new tyres ?
They should but they don't always do it. Especially if you go to a cheap place.
Just thinking, as you say 'it's been a while now' do you mean the previous tyres had the same problem? If so it is more likely to be damage to the wheel rims that means the tyres can't seal fully.

Yeah been an issue for ages but I've been too lazy to get them sorted :) if it is the rims is this expensive?
So you had a problemwhich started some time ago; you then replaced the tyres but the problem remains?
If it is the wheel rims , which now seems the most likely answer, then you need new wheels. Two good wheels from a scrap yard is the cheapest option. If you have alloy wheels it will be more expensive than plain steel ones. But there are places that can repair and reseat alloy wheels and remove dents and dings that are causing a problem with the air seal for the tyres. Get a good tyre fitting specialist to look at the problem.
As EDDIE51 says, wheel rim damage or as in my case, the inside of the rim has deteriorated and is pitted. This allows air to escape between the rim and tyre. Mine were fixed by having the tyre removed, the rim cleaned in acid and the edge sanded to remove the pitting. The wheel was renovated and the problem cured, cost about £100 per wheel.
Bready....how old is your car ?
Alloy wheels can be a mare. I had a problem with front nearside a few years back. Despite valve change and the tyre off 2 or 3 times and the inside rim being scrubbed and cleaned it still needed air every 2 days. A pal in the local , a very experienced garage workshop owner, pointed out that some alloys particularly if they have sustained a shock blow due to say potholes and the like develope a very fine hairline crack that allows the air to bleed out. I was lucky enough to source a wheel on line from a write off and took a chance. When fitted it cured the issue. I was also lucky that it was the same age and appeared just as the other 3. I will have a look and see if I can find the website. It may have been ebay.
"They don't have a puncture as they have been replaced"

Famous last words, there's no magical time in the life of tyres when they won't pick up penetrating objects.
In any event, take the car back to where you got the tyres fitted and get them to check and remedy the situation.
Often due to kerbing (hitting kerb while driving). Replacement wheel required coz yours wont hold rim sealant.
If you have an oldish car with alloy wheels they could be knackered. I first came across this many years ago when a colleague with alloy wheels suffered the same prolems as you and was told the wheels had become permeable with age. I had a Vauxhall Cavalier many years ago and after about 10 years I started getting the same problems. I persuaded a garage to fit tubes, which they weren't keen to do, but it fixed the problem. You might end up with new wheels.
They may be cracked.Take them back to the fitting bay and ask them to put them in the water bath.
leaky bead
The water bath is a good idea , if there is a leak you will be able to see where it is coming from.
Do you inflate them at a petrol station?

The inflation device in these places has to be pushed down onto the valve, and if you push sideways a bit it can cause the valve to unseat and leak. Put some soapy water around the valve and see if you can spot the leak.
Have you sorted it yet breadstick? It would be nice to know the answer for future questioners.
