A normal tire loses around 0.5 to 1 pounds per square inch of air pressure in a month, according to Popular Mechanics magazine. If your tire loses much more than this, you might have a tire leak. Losing air from your tires as a result of leaks is frustrating, particularly if you have to keep stopping at service stations to fix the problem. Checking all elements of the tire and the wheel rim is vital to try to identify the cause of the leak.
Check your wheels, rather than the tires, as this might be the cause of the problem. The wheels might be damaged or uneven, particularly if the vehicle is old and has alloy wheels. As a result, you could be losing air and getting results. Simply changing the tires will not help. Take your vehicle to a service station and ask a mechanic to straighten your wheels before putting on new tires.
Inspect the tires to make sure there are no obvious signs of punctures or damage to the tire casing. If there is a sharp stone or a nail stuck in a tire, this could be leading to a loss of air. If there is a small hole in the tire, you can buy a small kit to repair it from a good auto parts store.
Look to see if the rim is damaged. A rim that does not fit properly can be the cause of leaks. Another possible problem is air leaking from the area where the tire seals to the rim. In this case a specialty tire outlet could clean and apply a sealant in order to try to fix the problem.
Identify whether the tire is seated correctly on the rim. If not, you might have to change the tire.
Check that the valve stem is not leaking air. The valve might have failed, and you will need to replace it.
