What is reasonable here? (Details)

A kid rammed my parked car in late March. The auto body shop had my car for 2 weeks completing $6,500 of work on the front end of my car, including fixing a bent frame. I got my car back April 5th.

Two days ago I was giving my car a quick look over and discovered that my back left tire is dangerously worn on the inside. By that I mean there is a one-inch worn area where the metal threads are exposed several millimeters. The tire could blow any minute.

All 5 tires (spare) were purchased at the same time last fall. I drive an average of 8,000 miles a year. I need a new set of at least two tires because of the worn tire.

I went by the auto shop this morning and the mechanic told me they failed to align my tires after putting everything back together again, and this is what caused this unusual wear.

I feel it was only common sense that they should have aligned my tires given the bent frame and the tearing down of the entire engine compartment and front end of my car. I agree I should keep a better eye on my tires and I went 2 months without noticing this extreme wear to my tire.

The mechanic told me he intends to call the kid’s insurance company and put in a request that they pay not only for the alignment that was originally neglected, but also for the new set of tires because it was the accident that ultimately caused the damage.

I don’t know how I feel about that. Obviously I need the alignment and the tires, but who is responsible financially?
