I remember that thickness of the runway is one thing but the
major factor really depends on the "distribution of weight"
over the wheels of the aircraft.

I forgot where I read it but the distribution of weight on a
MD-80/DC-9 type of aircraft is not as even as, or not as "light"
as a 747.  The 747 has more wheels to spread over its weight 
while the MD-80/DC-9 has fewer to do the same.
