I also am not sure what the weight difference between a 215/55/R16 vs a 215/50/R17 tire is?
We debated this on another thread a while back. IIRC both are between 20 and 22 lbs.



Car and Driver did a study on this. They showed predictably that increasing wheel diameters on the same car resulted in increasingly slower accelerations and lower fuel economy. But reducing the wheel/tire weight by 5 lbs (e.g. 18in to 16in) increased acceleration by 0.2 seconds and fuel economy by 1 mpg (4.5%). Not really a great tradeoff for giving up some handling ability.
