recently went to workshop. front left tyre had a nail, front right rim dent a bit. Got all this done (patch and repair rim + balancing) at RM60....next time will be careful for pot holes..

maybe the tyre is faulty. it could also be the valve. simple solution...change the tyre.

I had similar problem like yours. Eventually found out it was tire problem. I asked the shop to loan me an old set of used tires just to be sure. After 2 weeks there was still no leak. Confirmed tire problem. Like you we did soak the whole wheel inside to look for leaks. There was none.

hmm... i recently had a problem similar like this, where my left rear tire would mysteriously but slowly be deflating over a weeks time (every SUN had to pump air into the tire)... went to the workshop... said tire ok, but when put in the water basin... WAHHHHH... it was the rim that had a hole on it... don't know how it happened but my stupid metal rim was punctured wei.... anyways, went to SUNWAY and got it patched up for RM35... so check ur rimslah, cos you never know rite???

had same problem wif my front left tyre.

soak in water, no bubbles, but my rim got repair mark that is only visible when u take the tyre off.

suspected that the mark was the problem, i changed my rim (thanks to zth, got it from here !)and problem solved.

ask a tyre shop to loan u a tyre. use it for few days and see. if ok means ur tyre got problem lor...if using different tyre, same problem appear, it might be ur rim laa..just like mine. sometimes soak in water oso no bubbles...

hope u'll get over it. i know how irritating it is.....2-3 days gotta pump air..

cyt,

how old is your tyre, i suspect some part of your tyre become hard, it wont leak air when u take out the tyre. only leak when u park your car at certain angle only.

try to check the tyre at nite, push the car by yourself and get close to hear when there is some air leaking noise.

or u can check after tyre wash, u might see bubbles when u turn your wheel.

 

[gohkokeng]

the best way is......u take your leaking air tyre.....take to workshop there...ask them put the whole rim with tyre in the water tank and slightly pump the tyre.....see got bubble coming from anywhere or not......if got the u know where got hole liao......tampal it.........if don have........

change all 4 tyres la......change bigger and nicer RIM as well hahahaha

 

[andy_lka]

haha, mine got 2 rims kena ketuk

kesian....thiking wanna change rims...but most of the design there doesn;t suits my car...

wut u say r true, MUST REALLY CAREFUL OF THOSE POT HOLES...
