Actually the H rating is something like 85 m.p.h. (hence my "highway").
I was gonna get the "Z" rated tires because I will probably travel at
sustained speeds over 120 m.p.h. in my two ton loaf, but only through school
zones and in town.
I would therefore assume "Z" is for zero because how many people drive at
sustained speeds over 120 m.p.h. anyways?
[You live somewhere where vehicles travel at 145 m.p.h. on the highway
routinely? Must be the fabled German Autobahn? Funny, the stoic Germans have
the greatest incidence of overtaking collision in the World; where death,
dismemberment and serious injury occur routinely. A little too much faith in
the flashing of their Bosch headlamps?]
