number of things

1) could be a nail in either tire causing a slow leak
2) could be a bad bead around the rim causing a slow leak
3) the needle in the valve stem could be loose and if there is no cap on the valve stem it will leak
4) someone let the air out

How old are the tires?

Aluminum rims can be porous and the air can actually leak out through the rim. GM goes into great detail in the factory service manual describing how to repair a leaky aluminum rim. Probably not your problem, but just something to consider.

/\ /\ /\ Lees right I had an old ass Firebird wheel that leeked air right thru the wheel itself.
True it is very rare but this is the main reason why aluminium wheel are clearcoated.
The clearcoat helps to seal those leaks. You'll need to put the wheels into tub of water and look very closely at the rim itself for tiny little bubles. If you find any the wheel can be fixed but it requirers takeing the yire off and takeing it to a shop that can weld aluminium. They'll remove the bad section of wheel and weld in new metal and the leak will be gone. I know it sounds weird but I had to do it on 2 wheels at 2 different
times. It only threw off the balence by a 1/4 once so it wasn't bad at all. Oh and the fix cost me like $30.00 each so it was worth the price.

good luck.



Semper Fi SAINT. May you rest in peace.

Hi ya'll. I had a Camaro several years ago with the old Cragar Slot wheels, the aluminum leaked right through the wheel. At that time not many people in the sticks
where I lived would weld aluminum. I dismounted the wheel, and liberally sprayed
wheel where the tire usually is with auto clear coat. After about 4 coats, and let it dry
well re-mounted the wheel and it never leaked again. Might be worth a try with
a spray-bomb of clear.
