Note to Moderators...you can move this to General Discussion if you want....
Yes, interesting that they didn't actually test the different tires for rolling resistance to see if the manufacturer claims can be substantiated. But then again, it's the myth that "tires with low rolling resistance are a good choice" that they are debunking.I've always been curiuos how much an "eco" tire really attributes. It's interesting to note that they didn't give any real numbers. The theory makes sense, but how much does it truly help in real life driving?
I've seen that test. Do you call 45mph your highway speed? Not in my world. They seem to have chosen 45mph as an average of ALL driving speed, not 'highway'.Mythbusters did the windows up vs. windows down and showed windows up w/ AC on was more economical on the highway. And I trust Mythbusters much more than Yahoo....
Drag force goes as speed squared, but drag power goes as speed cubed.Drag is a function of speed squared.
