Has anyone had problems with tires losing air excessively every few days, particularly in cold weather?
The dealer cannot determine why the tires lose air. They have taken off wheels and sanded
them to ensure good seal yet the problem persists. Have to put in air every few days. No
problems with tires or valve stems. Everything checks out fine, yet problem persists. It is
I had a similar problem sometime ago on one aluminum rim and it was the corrosion on that sealing bead area.Once i installed new tires with the bead area sanded it was ok no more pressure loss.Try installing inner tubes.
Have the entire wheel submerged in a water tank and wait as long as it takes to get bubbles. If air is leaking, it must me coming from somewhere. Tires and valves can leak so slowly that they are difficult to check with only a soapy water spray or brush. More than likely, it is the tire. Cracked wheels are very rare... Are the wheels steel or alloy? Steel wheels have potential leak spots where the wheel is welded.
Thanks for your response. The wheels are alloy. The tires were submerged but I don't know how long they stayed so. I will look into your suggestion.
Thanks for the info. Will give it a try. The dealer did sand the wheels, but the problem is still there.
Thanks. The wheels were sanded, but there problem is still there.
I'm currently having the same type of problem with my 2008 Passat. I replaced my tire and it's still losing air. I've had it looked at by several different garages and nobody can seem to find the problem. They submerged it in water and no leaks. There's no visible problems with the rim or the wheel itself. I'm currently sitting at work and I knwo my tire is going to be flat when I go out to leave. It's so frustrating!
I am sorry you are experiencing this problem also. It is so annoying it makes you feel like getting rid of the car. A week ago the dealer replaced the stems. They attach to the sensor system inside the wheel and are pricey. They are about 200 to replace for each wheel. It has been a week and no air has leaked. However, the temps have been mild, so I will see what happens when the temps get i to the low 20s consistently. That is when it happens. Hope this helps you. Good luck.
We have the same problem with my wife's 2003 Passat. She has ruined several tires because of it. We had the wheel sanded and treated but still have a leak. We are thinking of replacing all the wheels but I'm not sure that will solve the problem.
I have the same problem with my 2010 Subaru, the tires are constantly losing air and nobody can find the problem. On my last visit to Subaru they told me the tires have dry rot....sounds like B.S. to me!
Two things: First is the age of the tires. If they are too old, as in after date of manufacture, they can seep air out in so many tiny holes that they don't show bubbles. No tire should be in use more than 5 years, and never more than 10 years after manufacture. The second problem can be with the rims. Some alloys are porous. If you damage the clear coat, the air can seep out through the rim itself. When you have a chronic problem like this, the sure fire solution is to replace the rims, and I would go with a good aftermarket manufacturer rather than the expensive factory replacements which will only develop the same problem later. One other thing: Never run alloy wheels in the winter. The salt causes all sorts of problems. Have a set of true winter tires on steel rims. They may not be pretty but the are a LOT safer than any all-season, and the expensive alloys will be preserved.
