Monday, September 29th, 2008When car companies want to increase fuel economy one of the first places they look is the wheel and tire setup; the less rotational inertia and frontal area the better so the narrowest, smallest tire that will effectively carry and redirect the car’s mass is best.
Would you notice? Some would say no, but as someone in the market for a Prius recently pointed out those with the optional 16” wheels report having a hard time matching the observed mileage of those with 15” wheels. So I’d argue that you can’t break the laws of physics (and tell Prius buyers if fuel economy is what’s most important 15” alloys do best of all).
So when you see someone in a hybrid on larger, wider, heavier aftermarket wheels do what I do…
...shake your head and look at the driver with a mixture of pity and disgust.
