    I'm pretty psyched... I just installed a 4" pro-comp lift with springs in front, 4" blocks in back w/1" add a leaf... I mounted on 15X8's w/35x12.5.15 Question: It seems to look kind of narrow but I like it 'cause I didn't have to cut any sheetmetal... Would I need to do any trimming if I moved up to the Eagle 589 15X10's with the same tires??? What would the offset be? Any cutting necessary?

    Eagle 589's 15x10 have a 4'' backspacing. Your truck looks narrow because the rear axle is 3'' narrower than the front, maybe invest in wheelspacers for the rear axle before you drop the cash for 15x10's

    15x8's will keep the bead seated better on the tires. I think backspacing determines how much your tires stick out vs rim size.

    While I don't doubt there is no rubbing while driving on the street, if you ever do get into any type of flexed out situation off-road they will rub.

    Going from 15x8's to 15x10's (assuming they have the same backspacing) will probably cause the tires to be closer to the fenders and thus more likely to rub when turning. Years ago I switched from the stock 15x7 rims to 15x10's and they definitely put the tire closer to the rear edge of the front fenders when turned.
