Quick tire question for you guys - lost PSI on a new tire
I posted this on the tire forum too, but I figure you guys may be a bit more focused over here. 
So I got 4 new tires today, and had them mounted. After a little bit of driving, I stopped, and pulled over to check them.
One of the tires was almost flat, down to around 4 PSI and sagging on the floor. There was a hiss coming out of it. I filled it back up to normal PSI, and drove to a place to check it out.
They said that there was some air escaping through a bead in the tire, I guess some corrosion on the rim got a bit of the tire bead and made it leak air. The tire was driven on a bit with the low PSI, it did get a little bit of the lettering on the side scrapped off, but nothing too deep - the guy said it seemed fine, no bubbles, etc. He resealed it, and filled it back up, and it seems fine.
Is the tire really fine after all of this, or should I try and get it changed for a new one? I got it from tirerack. Will this tire be safe? It seems fine now.

Re: Tire Leak
I'd get it replaced, the sidewall will be weakened from driving at 4psi. The installer should have caught this leak before you left. You bought 4 new tires, not 3.

The tire seems to be fine, another guy who seems knowledgable looked at it. He said there were no bubbles or anything, just a bit of the rubber had been rubbed off from driving it a bit at lower PSI. I'll see the next few days if it holds the PSI, any small issue and I'll replace it. Otherwise it should be safe right?

This is a picture of the damage, the rim/tire are a little dirty from the installation grease and brake dust, but you can see a bit of the rubber was edged off. The guy who looked at it said it was fine and no damage was done to the internals, so is it just cosmetic at that level?

You paid enough for your car, I am sure you can spend another $200 to keep it right.

Make sure your rim is not bent or leaking air. take light soap water and run it through the rim and tire border a few times (both sides would be nice) and see if any soap bubbles up and are being pushed away
I would also find a new tire guy!

I just ordered the new tire - and I am very impressed with tirerack! I called them, and told them what happened, and they said no problem, Continental has a warranty/road hazard program for any reason - so they are sending me a new tire, and will credit me back that tire when I send my old one back in.
Awesome! That resolves it.
