Does this look like normal tire wear to you?

Okay, I have Bridgestone Potenza RE950's with around 3,000 miles on them. Not autocrossing or hard driving yet. Not lowered or anything. They are directional tires. I just got them aligned, rotated, and balanced for the first time since I put them on. Cold air pressure was a bit low at 26, however. I'll fix that right now actually.

The file labeled "front" are now on the front, they used to be on the backs. I don't think they are worn too bad.

The pic labeled "back" is now on back, used to be on the front. These ones look pretty worn to me. Look particulary on the side of the tread, looks sort of cracked up. It was always aligned, but I know my tie rods ends and TC rods, along with bearings or rotors are causing some shimmy when braking and crusiign at 55mph.

Maybe I'm just being paranoid, but the set that used to be up front looks alot more worn for only 3k miles.
