how does using smaller tyres on a car improve it’s range/fuel efficiency?

220 views

From my theoretical understanding shouldn’t larger tyres give you more range? My reasoning being that larger tyres = more distance travelled in a single rotation.

In addition to the other good explanations regarding tire width, and rotating mass there might be confusion about tire diameter and people miscalculating their range when they change tires. If you swap your stock tires for a smaller diameter tire your odometer will not know that a shorter distance was travelled each revolution, so your odometer will falsely show a greater range than you really achieved, leading to perceived efficiency gains that aren’t really there.
