well, see, actually, it's the same answer/theory as the water pump
thread:
if the spare tire is bigger, then the distance around it is greater so
the water pump has to work harder to overcome that greater friction
losses, so the pressure is obviously higher and the hoses have to cost
more. :)

what bothers me is that no one has mentioned the slight, albeit
important, extra pressure induced by driving in clockwise circles
(like around a mall) in the northern hemisphere (or counterclockwise
in the southern hemisphere), due to the coriolis effect. this is the
main reason that watercooled Vanagons cannot be used as racing
vehicles: the cost of reinforcing all those coolant hoses is, well,
just too pricey even for racing team budgets.

is it Friday YET!!??
