Re: Tire Size Question
In that case you remember this.
"Every object in a state of uniform motion tends to remain in that state of
motion unless an external force is applied to it."
This is Newton's First Law of Motion, which is essentially the same as
Galileo's concept of Inertia. You do not observe this principle in the case
of a vehicle, because rubber tires dissipate energy and there is friction in
the wheel bearings and air resistance. These three factors have nothing to
do with the mass of the wheel and tire combination. However, mountain bike
tires will be filled to a lower air pressure than road racing bike tires,
and so will dissipate more energy. The same holds for any larger than stock
tire on a Jeep.
I have not done or seen any formal study, but I think that the main factor
to consider when changing tires is to maintain the same rpm to road speed
ratio. This is what we call "gear inches" in the bicycle trade. How far do
you go for each turn of the crank? If you change this factor, you will
change available power and economy, in many cases for the worst.
