You can do it that way, and you will also find that tires of the same size will vary quite a bit in some cases, and, they do make tires in several "sizes" so you can at least get a pair for the rear that will give you as much stagger as you think you need. Tire pressures do make a difference, these are bias ply tires, so they respond to tire pressures pretty rapidly. I prefer to buy and mount tires, and measure them, then if they are close to what I want, with 8-10 psi, I can work with them to change the circumference as little as a quarter inch, or as much as a couple of inches, depending on how big the tire is to begin with, larger tires, more stretch, and you can stretch a tire by airing it up, and laying it out in the sun, just about anything you can think of, will make a difference. Good luck! Bob
