...but smooth on the inside running on 17" rims (according to the Discount Tire dude). 215s front and 255s rear.

What's going on? I'm lowered around an inch all around. My alignment settings are very close to the stock settings.

Can I just flip the front S0-3s right to left, left to right?

Got any pics dude? Getting the tires flipped on the wheels and swapping left to right is a start, but I'd be suspect of too much Toe-In too. Let me see some pics so I can scratch and sniff

who the hell asked you? just kidding.

the cuffing isn't so bad that they'll show up in pictures u know what i'm saying?

but the toe-in may have something to do with it. what if i flipped them and realigned back to stock settings?

I think the term is "cupping". This is when the lugs on the tires don't wear flatly causing each lug to be somewhat higher on it's (usually) outside than inside. It usually comes from inflation problems but can often happen with no obvious reason. And it usually results in a lot of tire noise.

Are you sure you just arent talking about uneven wear from the inside to the outside?

"Cupping" can also be a result of imbalance. I'm not sure what he means by "cuffing".

My wife's civic recently cupped some tires badly, of course I didn't hear about it until they were humming nicely at speed. The tire guy showed me the tires, each chunk of tread at the outer edge of the tire was clearly wearing unevenly. After having them replaced I immediately had the car aligned. The before/after sheets showed that the toe was WAY out of spec (I forget which direction), everything else was fine.

My bad. It is cupping.

Cupping on the inside, not the outside like I had posted.

Is it the toe? I can't imagine it could be the negative camber cuz it isn't anything abnormal. And it's weird to me that the cupping is occuring on the inside since I'm running the fronts with a lil' bit of neg camber.

But I think I did mess around with the toe a bit... I am lowered on aftermarket coilovers.

What to do? Appreciate y'all's input.

Zero toe in the front feels nice, and should be easier on the tires...
