I'm running 225/75/15 on stock wheels on my '98 2 wd with no rubbing. The speedo is not really affected either according to my handheld GPS it's right on. One word of coution on hte ford wheels. I know that the wheels on the shops '92 F-150 here have a smaller center hole opening, and do not fit, also most of the factory dodge truck wheels have the same problem.
