I had a leak in my LF of my SS from day one, lost 5-10 lbs a week. Turned out to be a bad bead. Then, 3 months later, my RF started losing 3lbs a week. Took it in, they found nothing. Got it back and noticed that they jacked the tire pressure from my 28-31psi to 35-39psi. Haven't lost any air since.

The cold reading (30 degrees outside) is 35psi. Warmed up, they reach 38 or 39. No more leaking but does this seem right?

The SS tires are rated for 44 psi...maybe the higher pressure seated the tire better?

 

The problem with mine (ss) was leaking of 2 tires near the bar code label which is vulcanized right on the bead. The dealer took care of it with a bead sealer, and I haven't had to add air since. GM must be a bit pissed with Michelin, since this seems to be a very common warranty repair/complaint with the SS.

 

Glad to see I'm not the only one. My LF loses air also, seems to have gotten worse since it has gotten colder outside.

besides going to the dealer or tire shop to get these leaks corrected, as I said in my earlier post, go to the local auto store and pick up a air pump for your ride. I bought the least expensive one for $20. And although it takes a little extra time, it works great. I bring up the tire pressure on the DIC, plug the pump into the socket on the SS and let it pump. Also I check the reading with a tire guage, and it matches the readings on the DIC, so I know it is accurate. Again you should check your pressure every week or two. It only takes a few minutes and you will be surprised at how long your tires will last. I have always had great success with tire wear.
I have close to 14,000 miles and my tires look brand new......
As a side note, I always run 30 to 31 psi in the tires, I have found for myself that is the best pressure to use, anything higher or even lower, you lose ride quality. And I do feel that there are better tires out there, but they will have to wait until these wear out, and that may be a long time.......

 

I too have started out at 30 PSI on my tires. I am glad they are wearing for you at that amount.

I also have put in air pumps in all my cars. they can be a life saver to get you out of an area where you can't change a tire safely. Also I have had times the rear tires on my GP do not want to come off the hub without a good hit with a rubber mallet while rotating the tires. On the road and no mallet or pump could be an issue.

 

I also carry fix a flat in my other vehicle....that also has been a life saver..
I think if more people keep up with proper tire maintance, they would eliminate some of the complications that may arise.......

yes 30 to 31 psi has always worked for me, I have over the years tried higher pressure, but did not last long, the ride was not good, not bashing anyone, but I don't understand running 35 psi or even higher...what benefit does it give you???? and don't tell me better rolling resistance and better gas mileage, because the increase you would see from that is so minimal, that the harsher ride is not even worth it....
oh well just having a mind vent
the lesson for everyone here from all of us to ourselves is that "safety first."
proper upkeep of what we have will give us years of fun and enjoyment

 

Well, add me to the list as I have one that constantly looses air.
us know what you fimd after the dealer fixes it.

 

I agree people do not care for their tires as they should. The many times I am behind someone with a tire that is 10 pounds low and they just keep driving.

That whole Bronco thing with blown Firestone tires was all about Cheap OE tires under inflated and over heating till they lose the tread. The owers were more at fault than Ford or Firestone.

As for Fix A Flat I hate the stuff. I worked through High School and Collage at a gas station and people would put that stuff in and you would have a heck of a time finding the leak. Unless it had a nail or large leak it was near impossible to find till it leaked again. I would clean it out and over inflate the tires and hoped it leaked.

I know it is good for many people but it still haunts me!

 

I hear you on that, but you have to admit it does work
