well if you look at my pictures i have 235/75/r15's.....
when i bought the truck i had 31/10.5/r15's on it i have read threads saying that if you get big tires say 265 or 255 it will need a slight trim

i dont know if i have a lift can somebody help

 

Do you have any larger pictures? All the ones in your album are too small to see much detail.

If you can take pictures of a few places, it's easy to see what kind of lift.
Try and get a picture of:
-The body mounts, just take a pic of the how the body rests on the frame
-The CV axle, turn your wheel out to the side so you can get a good shot
-The rear shackles that attach the leaf spring to the frame.

 

i will see what i can do i will do it later today and have it by tomorrow

 

Also take a picture of the rear of the torsion bar, there will be a verticle bolt which I'm assuming is turned up a bit it looks as though your truck is fairly level.
