I would love to see what other have gained in FE by overinflating their tires. I showed zero difference in my month to month test. First month (last Aug) ran at +5 over recommended (I got 51mpg ave. over the entire month). Second month (last Sep) ran at 51 psi (max), and surprise got the same average. I now run at around 46psi for the gains that I noticed in the rain and cornering... along with braking (in both dry and wet).


As for the part on modding a hybrid, if it's for better FE... sure it makes sense. As for the crowd that will mod a hybrid at the expense of FE, I just don't get it. I see post here where the person doesn't like the OEM wheels and then replaces them for a "better looking" wheel at the expense of FE. At which point I must say, why bother getting a hybrid. You are now getting the same FE had you purchased the non-hybrid version of the car.
