We have two tires with radius r and R respectively. They are connected to two almost identical vehicles with same net mass.
"Almost", because Gear ratios are adjusted such that At equal Engine RPMs, both vehicles have same road speed, on paper at least.
So, does this have any effect on the offroad performance, hauling performance, fuel efficiency, and power output of the vehicle?
What else effect could wheel size have?
Would the effect be different for different vehicle builds, like semi-trucks, minivans, bikes, muscle cars, and race cars?
This question is just a thought experiment, so contruction cost, logistics, looks of vehicle etc do not need to be considered.
r is small radius and R is large radius
