I agree for sure on this point.  Keep in mind that the tire
manufacturers allow up to 3/8" or so difference in their tire dimensions
on each model, not to mention the difference in contours/radii if you
change from one tire model to another.  A perfect fit for your first
tire set may not allow enough room for your second set...  Always swing
the gear when you change tires to make sure you have good clearance.
