The tires are fine...its probably my rims. They are the old Outback 15" rims. Weird thing is...rear tires will keep their pressure for months at a time...but the front get really low. I am to cheap to buy new rims now, so I was looking for something else. Is there like a glue or something I could put around where the tire meets the rim? Any idea why the from loose pressure and the rear don't?

Mattocs:

 

Had the same problem with one of my 15" OB rims, some weeks it lost 1 psi per day. Took it to shop #1, they said there's nothing you can do. Tried again at another shop (don't give up), they said, "Oh yeah, those Subaru rims have that problem sometimes, I think we can fix it." They buffed the bead of the rim to smooth it out, put the tire back on, and that fixed it 90%. Still have to check it periodically of course, but now I can go for weeks w/o having to put air in it, as opposed to a few days or a week.

Ok, thanks. I was just thinking about going with some steel rims and hubcaps if these kept leaking. I might look into some alloys depending how much a nice set will cost...but that'll be this summer if I do buy any.

One thought: If you haven't tried snugging up the valve cores, that might be the next thing to try. Sometimes they're not completely tight and they'll give you a slow leak.

Mainly just a reiteration of what's been said, but I remember I posted in this recent thread too, same question.

I have an 89 Taurus with wheels that are a bit corroded and they were starting to leak at the beads and in one case at the stem hole. The local tire store did a light polish by hand which helped on two of them. The other two were dismounted and remounted with some sticky black stuff made specifically for the purpose of sealing the beads. It completely fixed the problem.

Yeah, make sure the person mounting your tyres uses a sealant on the rim.

take it to a shop, tell the guys to take off the tires (all four, or just the worst) and tell them to sand the rims to get the corrosion off from between the rim and bead of the tire. Also, you need to air up your tires every couple of weeks. tires lose pressure, thats just how it is. especially in the winter, your tires can lose up to 5psi per 10 degree change in tempurature.
