2005 Chevrolet Colorado suspension problems

I have a 2005 chevrolet colorado 4x4 truck. I was getting over in left hand lane to avoid a truck and trailer that had stopped about 4 car lengths ahead of me when the front passenger tire snapped off the spindle and sent the truck down into the road. The hole tire snapped off and flew by the window taking the mirror and door handle with it. The tire was not flat and still had lugnuts fully locked on it when I picked it up off the other side of the road.

I took my 2005 chevrolet colorado (purchased in late june 2005) in for a pennsylvania required vehicle inspection. The inspection station refused to inspect the vehicle due to tire ware and improper front alignment. I made an appointment at the dealership to check the problem and vehicle inspection. The dealer informed me my vehicle had to many miles on it for the warranty to cover it. I have not had the vehicle for a year yet and the alignment is already out and tires are worn.
