The axles have no measurable tow out or toe in.
The axles are square to each other.
Checking from the front axle tires centerline to the kingpin center the left side if forward 1/2".

The fact that 3 of the 4 tires have an abnormal tread wear and the bolded statement tell me that something is wrong. The axles can be parallel to one another but if it isn't square to the pin/frame then it's going to "crab" going down the road resulting in the tires scuffing and premature wear as the force on the tires will not be parallel to the tread.

I hope you get the alignment checked before ruining that new set of tires.
