MG4 wheel swap efficiency hit tested

[JonnyG]

.... plus he has mud flaps fitted ?? ... I guess every little bit adds up

I wonder how you swap out the wheels and get accurate readings when full rotation is now PI*19 .....

He says in the video that the rolling diameter is exactly the same ? ... but wider wheels & tyres.

Regardless of the rolling circumference, there is a clear difference between 215 and 245, I also knew that when I was still driving a combustion engine ;-)

In this case, the new rims are heavy ones. But I'm thinking about what would happened if the new 19" rim were a "light" 9kg one like superliggera or Similar, and not a 12kg model like this. The change in the surface in contact with track would be higher but not the weight.
