Yey me... After my tire blowout on the freeway (http://forums.bradbarnett.net/showthread.php?t=475490) I had two new tires installed in the rear... So far so good...

When I came back from vacation (was gone for two weeks), my battery was completely dead. I jump-started it once and everything was okay, but when I tried again yesterday, dead again.

Sooo, I went out and bought a new battery and it was starting again. I took it to the gas station, and the rear RIGHT tire didn't have hardly any air left in it. Filled up all the tires to 35 psi, but when I checked again this morning, now the LEFT rear tire is empty.

Did the shop mess up when mounting the new tires or am I just reaaallyyy unfortunate? Anybody experienced anything like this before, I mean new tires not holding air?

This Mustang-Year is not off to a good start....

 

aint got a neighbor thats pissed at you or something do you? hope noones messin with your car.

 

Hope not, I park in the parking structure at my apartment complex, so I can't really **** anybody off... It's also not THAT loud...

 

Sorry to hear this, maybe it's the tire bead that's bad? Happened to my girl's firebird. The tire wasn't installed properly. Good luck!

 

I'm reasonably sure we're talking aluminum wheels. I'm also reasonably sure we're not talking rust. But I've see this before, and I have The Fix:

Go overinflate the tire by about 5 or 10 PSI (This is a temporary thing, so don't worry about it.) Go to a store and get a rubber mallet. The order of these two items is up to you. Then go home.

Take an affected wheel/tire off the car. Place face up on the ground on a soft surface, such as the grass. You may want a towel between the wheel and the tire.

Now take the rubber mallet and *BEAT* the sidewall of the tire. Dont' miss, but that's why you got a rubber mallet. I mean give it a good whack. Do this around the entire circumference of the tire. Probably about 12-15 whacks.

You may notice how little silver ***** show up at the rim of the tire. These are little ***** of aluminum that are generated due to friction of the beads in the wheel. This is what's causing the issue, most likely, the ***** cause pinhole leaks about the beads.

Once you perform this task, flip the tire/wheel over, and repeat on the other side (this is the soft surface/towel reason.) Flip it back, and repeat over and over until you stop seeing new *****.

Reset the PSI in the tire to the correct pressure and put it back on the car.

This happened to be on my 86 SVO, just after I got new tires, the front ones kept leaking down. My mechanic at the time showed me this trick, and explained it. It worked like a charm, they never again leaked down.
