Last year I have done some testing. Previously I had 4 michelin energy saver (We have 16" tires here).
I drive at constant 70 km/h (44 mph) with this 4 tires and used 570,9 Wh on 5430 meter. This is not a good surface road but it is in a forest then absolutly no cross wind.
I changed the 2 front tires with Toyo nano 2. On the exact same distance, same day ... used 525,9 Wh. So
7,9 % less energy used ! Temperature was 23°C, no Wind. With my P2 plug-in so 55% load on front tires.
Of course now the 2 rear michelin energy saver being used have been replaced with 2 toyo.
