2006 Toyota Matrix suspension problems

Jan. 2007 anchorage, ak driving 50MPH on a highway, as the road bended to the right, we went into the turn and began to slide sideways. It was 30 degrees f, so we must have hit black ice. I tried to correct and sent the car fish tailing to the other side. We whipped back and forth a few times, before the car started to spin. We did two full circles before we gently hit a burm of snow and came to a stop. No other cars were oncoming so we did not have any significant damage and there were no injuries.

Own a 2006 matrix and had all 4 tires ware out on inside of thread with 21000 miles on car. Did not notice the problem till car went off road hitting a tree. Repair shop said tires were worn excessively, and car shouldn't be driven. Upon repair, car was taken to have front end aligned and was told it was within toyotas specks, but could be corrected to a tighter standard.
