Not sure what you are looking for here, so my answer might just fit my thinking on this. Wheel base is measured fron center of front wheel to center of rear wheel, this measurement is wheelbase. Track , the way I understand it is measured from center of tire tred left front to center of tire tred right front, this measurement will give you front track width. Rear track width is measured the same way only on the rear. Tire size(width) and wheel ofset or back spacing affects track width. For example reverse offset will widen track width and a wheel that is back spaced deep on the back side will narrow track width. This may not be what you are looking for as I could not understand by your question exactly what you mean't. Hope this helps.
