    Slow leak in tire

    I have noticed a VERY slow leak in one of my tires. It looses about 3 psi after about a week or so. I've never heard of something like this before. I'm wondering what I should do. Don't want to spend a fortune. I have been going by the DIC and app for my readings. It's been really cold here and I haven't checked with a tire gauge. I was first made aware by the monthly email from OnStar. I usually fill the tires to 38 psi, being that they're not cold after driving to the gas station air pump. TIA

    Re: Slow leak in tire

    If it's leaking at that slow of a rate, check the tire valve stem core. It may need tightening. Sometimes these are not fully tightened from the factory. There are two basic types of tools to accomplish this. The latter is also a valve cap.

    Always check your air pressure with a "real" air pressure gauge. I prefer an analogue gauge for accuracy. The tire pressure display in the DIC should only be used as a general guide. Several variables prevent it from having pin-point accuracy. Also, no need to go to the gas station. You should have an air compressor in the floor of your cargo area. You have to disconnect the hinge on the storage bin door. Then, pull up (Velcro attached) the hinged front portion of the door. You'll see the air compressor sitting in a molded compartment.

    Thanks! Is this something I could get the dealer to do on my next service visit as part of my maintenance?

    A tire shop can find the leak and patch it for only a few dollars. I would not take a chance on possibly having a blow out.

    Yes, but I wouldn't wait if I were you. Just stop at Pep Boys or some other auto parts store. A tire valve stem core wrench is a good thing to keep in the glove box anyway.

    If it is not the valve stem leaking , I would check the seal around the rim, I have found a leak myself just my using some soapy water and a brush .

    The question is, can I simply tighten the valve stem core? I've been reading online and seeing that the car needs to be jacked up and the tire deflated. If that's the case, I'm not doing it myself. I'll get to the parts store to pick up the tool and see what I can do. I should mention that I don't know if this has been happening since I've had the car (7/27) or if it developed along the way. The other tires seem to be consistent. I'm at 29% oil life, so it's too soon for a service visit. Thanks for all of your feedback Sube

    Re: Slow leak in tire

    You have bumper to bumper warranty, use it as you may have a leak in the wheel and needs to be repaired.

    Thanks. I wasn't sure if that was covered. I'll call my dealer. I'm going out of town with the SRX for work very soon and need to get this then care of.

    The dealer is saying its not covered, but I did buy wheel and tire warranty coverage. I'm bringing it in tomorrow. The oil is at 29% so they'll do that too. Now I have to dig out my wheel and tire coverage.

    Yes, you can simply tighten the valve stem core without jacking the car up and deflating the tire. It's a simple threaded core. If you try to turn it and it won't turn, that means it's already tightened. If it's not fully tightened, it will turn a little. The procedure you described is for "replacing" the valve stem core.

    That's a premature assessment. How can they say that without even looking at the tire? You could have a crack on the inner surface of the rim. Did you do a visual inspection of the tire's exterior surface? If not, you should do this before you take it in. Have someone else sit in the driver's seat and slowly roll the car away from you as you inspect the surface. Nails, screws, etc. are the most common cause of a slow leak and they are usually very easy to spot.

    Even though they may be fixing it, whenever possible you always want to know what the problem is before they address it.

    OK, keep us posted. You may still want to pick up that tool just to keep. You'd be surprised just how common loose valve stem cores are in bicycles, motorcycles and cars.

    I had a nail in the tire. The tire and wheel insurance covered it. My oil life was at 28% so they went ahead and did an oil service and tire rotation. I only have 2700 miles on the car, which was purchased new in July. I have to recognize Crest Cadillac in Syracuse for fast friendly service. Dave Thompson, business manager, was very proactive and got me in today. Bob, service consultant, was also great. I will have no more air leak, a PM, and clean car in about 2 hours total. All at no charge to me. The wheel and tire warranty is good piece of mind IMO. Thanks Sube and Katie.
