i dont know the width size i need. im looking for a 50-55series sidewall on stockers... anyone know of any tires?

 

Do you have 16's or 20's? I will assume 16's on an 02'.
I really want to say that a 50-55 profile tire on a 16" rim will be a little too short.
Try looking at some 60-65 series tires. I really cant tell you an exact tire to put on your truck. Is it dropped or at stock ride hidth?
I would say a profile between 60-65, and a width between 275-305.
The best thing to do is see what your local tire shop has to offer for your truck with the 16" wheels. You will know if you like it when they mount one on your rim and install it on your truck with it setting on the ground.
Good luck.
