[Vwdiesel] Tire pressure

[James Hansen]

You want to watch that your hot pressures do not go above the do not 
exceed level as stamped on the tire. You will gain a few pounds pressure 
on a warm day driving on pavement verus checking them cool.
If you can stand the ride, harder gives less rolling resistance.

Might try a couple pounds more on the EV, they will run cooler and may 
last better.
If you go through front brake pads like socks, be sure the rears are 
doing their job. (watch for the front dropping on braking- it should 
normally, but not excessively which indicates the rear brakes are not 
braking as well as they should.)
