whats the cause of this tire wear? Options

[diegohiga]

So my both rear tires looks like this one on the picture.
I have megan racing coilovers and I know this wear sometimes is caused the the suspension and not because of toe, camber or caster.
Bt if my suspension is only 1 year old what could be causing this?

When I pass my hand around the tire I feel the thread going up and down

I don't think that would be caused by a wheel bearing.
In all the cases i've had bad wheel bearings, it got significantly faster as I sped up, and it was nothing like a scratching sound.
Although it doesn't hurt to check.

if the bearing is bad enough that your rotor moves a noticable amount it can start scraping on the brake wear sensor or even the caliper bracket causing a sratching/squeaking sound, happened to the front wheel bearing on my 94 GT once. You are right though that a bad wheel bearing usually makes a growling/humming noise at about 40 mph+ that progressively gets louder with speed.
