Help!

My truck is currently broke down. Bearings need replacing. If anyone is willing to help please let me know.

Your truck has several bearings. Which ones are bad?
Choices:
Wheel
Engine
Axle
Differential
Muffler
I don't mean to be sarcastic, coudn't resist.
Hope you find a solution.

It was the wheel bearings. That is fixed but now having trouble finding good used tires in my size. Then the truck needs an alignment.

What size tires?
