tire / wheel width range penalty
Over the weekend I found a few more cars which have optional wide tires/wheels which also suffer:
VW ID4
FORD Mustang MACH-E GT 'Performance' ( 10-miles lost )
Subaru/Toyota Solterra 'Limited' and ' Touring' ( 6-miles lost )
-------------------------------------------------------------------------------------
Mercedes-Benz reported that the front wheel aerodynamic drag of their VISION EQXX concept constituted 33% of overall drag ( Cd 0.0566 ).
Rolling-resistance is 20% of overall road load.
The proprietary Bridgestone concept tires designed specifically for the EQXX work out at a coefficient of power absorption of 0.003390449732, which can be compared to as high as 0.015 for some contemporary tires.
