It is possible you could find some spacers to move the wheels out slightly. This may or may not help, since you may still hit before the steering stops are hit. I am assuming from your post that you have the tires on the rims and they are not hitting the frame. Odd, you would think the tires would hit first. If you put spacers on, you should make sure they are suitable for your truck, because they create some leverage on the suspension - not much, but some. I would suggest you refrain from any performance cornering if you do put the spacers on.
