magwheels and tires
i just want a confirmation if my understanding is correct about mags and tires.
it doesn't matter if you are using 13s or 18s because:
smaller diameter overall=one revolution of your tire covers less ground but effectively spins faster per minute
bigger diameter overall=one revolution of your tire covers more ground but effectively spins slower per minute
what will affect economy will be the width of the tires. the wider you go, the higher the friction your engine's power will have to overcome. more contact patch=more friction=more energy needed to overcome that friction.
is this true?
