alignment can change from 5 months ago....and any type of pothole, rut, etc, can pull your wheels out of alignment or change the specs from last time.

Some places will look at it for free and only charge you if they change anything....

Talk to your dealership about it.

Even wear on the inside is usually camber is set too negative. Feather inner/outer wear is the toe being off.

BTW there are a lot of other specs you are missing.

Rear wheels dont have any camber adjustment since its a solid rear axle. Hows your tire pressure?

Did they rotate your tires when they did the alignment? Maybe used to be up front.

If you mean down the center of each tire, that'd be from too much air pressure, balooning out the tires. Tread not sitting flat on the road.

I have very unpleasant experiences with most dealerships, most are incompetent and sloppy. I havent hit anything that i know of that would change my rear so it should still be the same since 5 month ago.
Does toe out cause outer wear and vice versa? does it always cause feathering? When i ran my hands around the tread i didnt feel any feathering feature per say.

I did a little test with a quarter today, i have the backside of the quarter with the 2014 craving on the bottom of the coin stand on the tread wear indicator on the outside and inisde shoulders. The difference was not significant, outside shoulder wear stands exactly on top of the 2014 letters while the inside shoulder wear covers slightly like a hair or a tip of a needle above the 2014 letters. The difference feels alot more when i ran my hand back and forth. Also wouldnt that mean the outside shoulder is wearing more if the inside is covering more of the coin?

My tire pressure is up to spec recently, slacked off few month ago but the inner wear doesnt seem to be tire pressure related.

Personally i dont find tire rotation necessary if your alignment is in check, so long answer no lol.

No im talking about from outer edge to inside its wearing towards the inside.

Make sure the rear axle is tracking straight with regards to the front tire
It may look straight with the body lines but be out of square as far as suspension setup goes

Thrust angle is -.15 but still in range of -.5 to .5. Im still confused as why when i did the coin test on tread inside tread cover a hair more than outside when i feel more inner wear with my hand.......
