The Effects of Rotational Inertia on Automotive Acceleration
Shaving a pound from your tires is equivalent to shaving at most 2 pounds of non-rotating weight. That's PER TIRE, so a pound off each tire could worth close to 8 pounds of weight reduction. For wheels, the multiplier is closer to 1.6, so saving 5 pounds per wheel (20 total) would feel like

What is the Difference between Molarity and Normality?
Jan 02, 2018 Gram equivalent weight is a measure of the reactive capacity of a molecule*. Unit of normality is Eq/L. “N” is the symbol used to denote normality. For example, 1M of hydrogen chloride gives 1M of hydrogen ions and 1M of chloride ions into the solution. 1M of hydrogen ions is equal to one equivalent of hydrogen ions
