What are your tires getting eaten up by? Is it a wear problem or is it a tire rubbing the fender well issue? If your tires are just wearing funny, the putting bags in is not going to solve the problem, it might even make it worse. Sounds like it is an alignment issue.

It is a little more than just taking the springs out and putting in bags and brackets. In order for it to ride nice there is a whole lot of design that goes into getting the ride height where the bag is at its optimum pressure. Think of bags like tires. when you have a tire that is low on pressure and you turn a corner the tire will compress and roll and the vehicle will feel loose, same if you have over filled the tires, they will give a hard and bouncy ride as the tire is bouncing like a basketball. If you don't get the ride height calc'd in just right and you weld the brackets in the wrong place, and you have a deflated or over inflated bag to achieve the ride height you want then your ride will be worse than with steel springs. but if you do some math and get the proper set up so the bags are at their optimum pressure at ride height then you will have a better ride than steel springs.

Now you will notice that auto crossers and race cars still use steel springs for suspension, that tells me that bags are good for cruising and comfort but not great for performance, it all depends on what you want your truck to be.
