I have all season 20 in tires. Was running 44-45 psi on all tires. I recently tried 32-33 psi (comfort pressure) as I rarely go over 100mph. Car seems more comfy as well as better planted.

Any comments?

More pressure saves fuel. Flatter tires are used at dragstrip for better traction in rwd cars. A flatter tyre bends in corners and upon hard accelration and tire ware happens mainly on the sides of the wheels, in a hard tire in the center. My wheel expert suggested high pressure, 3.0 bars. It all depends on what you like sporty vs comfy, except in this case sporty is also more fuel efficient.

 

I have noticed the same - when I am about 40psi my mileage is far better then it is at 33psi
