The stock Comp t/a tires on the 95 Impala were very worn on the inside of the front tires.

What could cause this? The car doesnot have alot of miles on it.

Does the weak idler arm make the tires wear like this?

Check the front end parts (i.e. idler, centerlink, etc), and have the alignment checked.

Excessive negative camber or (far more likely) too much toe out can cause the tires to wear like that.

I had the same problem or worse my tires looked good on the ouside but on the inside the tread was gone some mettal was actually starting to show. I thought it use to rub on the frame or something when I turned to much but all I needed was an alignment. I had to replace the tires and my wallet is hopeing that the problem was fixed.

after several years of perfect wear, in 8000 miles from last fall through march I had the same symptoms.

The alignment guy said it was neg camber due to my sagging front springs.

If this is your case, ask to sit in the driver's seat while they align it. Guys have had measured results with and without driver so it is worth it.

I have the stock tires aswell, with 7 almost 8k miles on them. How do I notice if my tires are doing the same?

If the inside wear is severe, I would first check front wheel bearing adjustment (lift wheel up and push in on top and pull out on bottom of tire and then repeat in reverse order) and lower ball joints for play (both ball and stud).

I'm tempted to call BS on this statement. Don't our cars have backwards camber curves as the suspension compresses?

Yes, our camber curve is backwards (i.e. compression causes POSITIVE camber) until you get severely compressed.

That said, it is possible to align it so that negative camber becomes an issue....

I had the exact same problem. I just upgraded everything to a Moog front end kit. Not it's perfect and it also firmed it a bit in corners.

Also : I'll add that while sagging SPRINGS wouldn't cause negative camber, a sagging FRAME would cause it.

I think inside tire wear can simply be attributed to having a slight amount of negative camber. Any deviation from the proper amount of toe (either via improper alignment or worn tie rods, or ball joints) will only exacerbate the wear that the nevative camber was already creating. My 9C1 appears to be wearing the inside of the fronts noticably more than the outside. I do have some negative camber, but less than a full degree. I also drive it like I stole it most of the time. The one wheel peel is also not out of the question.

Same thing on mine, even down to the razor-sharp cords. Except the first alignment guy at an NTB said it was 'excess toe-in'. So, you can get multiple opinions on the same symptom. Everybody remarks on my "neat lowered front springs", -the stockers just really sacked out bad between '98 and '02. And that's ". . . A Good Thing . . ."

With the benefit of a 3-hour alignment on Hunter's best machine, the tires have been wearing great. No more cheap alignments for me.
