True, but these specs are given from the factory, and don't include the endless possibilities of aftermarket wheels and tires. Mopar factory wheels normally have a 1/2" positive offset, and thus the track, from center of tire to center of tire stays the same regardless of wheel/tire width. They provide this positive offset so as to better place the load more in under the inner bearing on the front spindles, which is more equipped to handle the load, as well as the spindle itself being stronger the further in you go. I am not in favor of wheels that have a negative offset, especially on the front. I like to see a minimum of 1/4" positive offset. The rear isn't as critical but still, the further the center of the tire is offset from being under the bearing, the more chance of stress on the axle shaft and bearing.
