Easy Easy, The offset is too much for your truck Simply measure an old wheel as per the following: lay a strait edge (Carpenter's square) across the REAR rim edge. using a tape measure, reach down to a flat spot near a stud hole upwards to your square. Jot this number down it's called: Wheel Backspace. when buying new wheels never alter this dimension. In your case lets fix your problem. Measure the back space on one of your new (Problem Child) wheels. Write the number down. Notice the difference between wheels. You need to machine new spacers that will make the new wheel offset the same as the old wheels. Regular CRS. works fine . If you can't find the diameter you need speed shops have sources for the spacers that you need. I've machined them myself at work. A big shot wandered into our machine shop one day with an old Micky Thomson wheel and it bottomed out on the brake rotor on his Corvette. I'm sure you've heard this story before. Super Dr's. of engineering , chemistry, ceramics and other eggheads are so smart their stupid.

Sounds to me like your backspacing is off. This means that your wheels are basically moved further towards the center of the truck. You should look into getting wheel spacers. I understand why you are confused because I was under the impression that the 89 and 91 were the same unless we're talking about 2wd vs 4wd.

the rims are too big so you need to get a lift kit sounds like the tires may be hitting the inside fender walls because again they are probably to big to fit properly. Go to a shop and ask a proffessional you never know maybe its a simple fix.

adjust your ride height and suspension or shave your wheel wells

Your back spacing is not correct,may have to shim them.
