Yes, both those will fit same rim
Tires fit onto the wheel rim
Which trim level and factory wheel option!? Depending on whether you have a Base model or Z26 (or any of the optional steel or aluminum rim sizes), you may have any one of the following: P195/70/R14 P205/60/R15 P205/55/R16
No, the R15 means that it is a radial tire and the 15 is the rim size. Never try to mount a tire and a rim that are different sizes.
No, that's going so narrow they may not inflate properly on a wide rim.
no you need a 16" rim
it not a question of if the tires will fit the truck, it is if the tires will fit the rim on the 04. check if the rims are the same size
15 inch tires from 185 to 225 width.
