Tire slow leak
 

How often do you need to check the tire pressure on newer tires? :confused:

Seems like I have to add air every few days to keep them up above 32psi. Seems like they should hold better than that for longer. I am going to take the car into discount tire today and see if there is a slow leak somewhere, any suggestions on where to have them look and to make sure they don't try to blow smoke up my .....:(

Thanks

Spray/dribble some water with dish soap around the bead as well as on/around the valve stem- then watch for bubbles

Even when I didn't drive the Buick for a year the tires were still @ 30 PSI when I started to drive it again. I would get those tires looked at. Also have them look @ the rim. On my old 74 Chevy there was one rim that no matter what you did, the tire leaked. I even replaced the tire and the new one leaked. I put an inner-tube on that wheel and considered it done. Never had a problem after that.

I took it in and three of the stems were shot and one had a nail in it so all four had issues. I guess living in phoenix I should get used to checking for dry rot. Thanks for the responses.

Discount tire co? They have an ongoing recall on valve stems.

The heat will kill tires fast!

1 psi loss a month is about average

Valve stems should always be replaced when you get new tires, something I've had to specify before when getting new tires. Glad to hear you got your slow-leak issue resolved.

I've also seen corrosion on cheap alum rims around the bead , the tires leak fast. Also on the electronic valve stems, they sometimes leak at the base after replacing a tire, they now have just the small seal available thats in between the valve and rim, you don't have to buy the $130 valve stem anymore.

-over 1psi/month should be looked at.
-if a shop doesn't replace your valve stems with a new tire, take your stuff and get out.
-leaking or not, check your tires at least every month. that way you find out if you have a leak before it's visible (which is pretty low for most people).

I've found aluminum rims are usually OK for the first set of tires or 5 years. once they've been ground with a brushwheel to clean them or regular weathering for a few years they usually need to be cleaned/sealed every 2 years. (unless you have chrysler rims, then it's every 10 months. or chrysler chrome rims then it's every 3)

The shop I went to said they replaced them and did not charge me because I am a long time customer, ok cool. Well today I decided to check there work. I found that the stems were not replaced and if you move them you can see large cracks. :eek:

I am going to try another shop, the one that I usually go to for my cars. They have gone down about 4psi each since I took the car in. I am frustrated but I guess that is to be expected when working with a national chain, the service is going to be hit or miss.

Thanks again for all the info here, it has helped me a ton with upping my mpg. :D
