YACT: Is it possible to inflate a tire with 0 pressure?

That happened in only a few thousand miles, if I checked the tires when I think I did.

The other side is just as bad. Guys on freshalloy say it's toe out, so I'll have to get an alignment too.

You weren't really driving on that or using it as a spare, were you?

I was driving on that. I didn't know it was like that. Like I said, it went from decent thread to that in a few thousand miles.

No alignments at discount tire. If your tire did that in a few thousand miles then something broke, and an alignment will not fix it.

Camber tilts the tire in or out in relationship to the ground, so more pressure is on the inside of the tire if you have a negitive camber. This will cause the inside of the tire to wear faster than the outside.

Toe in points the front of the tire towards the engine so the tire is actually scraping on the gound. This will kill a tire REAL QUICK but generaly, the entire surface wears relitively evenly. If your tires are below a certain pressure (don't ask me what that # is) the leading edge will wear faster as the other edge will lift off the pavement, so it is possible to get the wear you have shown, but it will be a mirror image for Toe in. Toe out and a low pressure may do that. maybe. ( too much toe in is worse than toe out.)

I still say that was too much Camber. Not that it matters in the end diagnosis. A alignment machine will have the final say.

<edit> your link doesn't work.

Could the camber be related to the clattering noise I've been hearing, that Mad Indian said is worn bushings?

Print up the tirerack page showing the price. Discount Tire will pricematch.

There was a huge thread in Hot Deals about 6 months ago about this.

Sure, the clattering can be caused by worn bushings along with 200 other things including debris The thing is, to cause the tire to change Camber or Toe, somethign has to be applying force to the assembly. It is not exactly easy to hold a tire out of plane of rotation. Loose or worn bushings usually cause a wandering feeling or clunking when turning.

My guesses:

Assuming it was caused by toe in: Something smacked the cross link in the steering linkage and bent it towards the rear of the car. This will cause the tires to point in towards the engine since the linkage was just effectively shortened.

Assuming it was caused by Camber: You taco'd both upper a arms. (since you sais both front tires are like this)

It could be worn bushings, but tire wear caused by that is sually splotchy, not even like that. But the clunking could easily be worn bushings, expecialy the ones on the anti-roll bar.


The steering wheel off center can be fixed by re-indexing the pitman arm on the steering box.

the thing that 007Silvia is talking about is called the "Valve Stem Core". It requires a spectial tool for removal. Just in case you wanted to know It also requires some skill to get back in since air will be rushing out as you are trying to screw it back in.

I did manage to put a 33 x 14.50 R16 tire back on a rim after the bead was blown with a 5 galon air tank by removing the core. It was all I had. I blew the tire when I hit a rock at a wheel speed in the 60's when I was mudding with about 15 PSI in the tires. I love my air tank. only cost me $15. I still have it in my zuk.

It's easy for tires to go to crap really quick if you don't pay attention to them, especially the inside edges. I once ruined a set of tires because of bad alignment. Basically the same thing happened--the inside edge was destroyed, and I never noticed. Now, every time I check my oil, get gas, etc, I run my hand across the inside and outside edges of every tire. If it feels smooth, you're usually OK. If it feels rough (the tread depth is uneven), it's time to have them rotated or aligned. This is a very simple check, and can save you hundreds of dollars plus possible flats. It's saved me before, and some friends whose cars I noticed it on. Hope this could be helpful to anyone.

Evadman, I said both REAR tires are like that... I think I said that anyway.

Edit: NM I didn't say F or R. I did in the other thread.
