Poor mpg 37/38 / Pulls legt when breaking

[bee13]

This happened to my Prius, too (i.e. pulling to the left on braking). My mileage dropped from 50 to 43 mpg so I knew something drastic had changed. After a little investigation, I found the left-front tire was about 20 psi lower than the other front tire. Pumped it up to where it was supposed to be and, viola, the problem disappeared. I figured I had developed a slow leak in the tire or valve stem and watched it closely for the next couple of weeks but the pressure never deviated again. Not really sure what caused the low pressure...

My problem turned out to be simple to isolate and fix. Hope your is the same.

Well, it depends if you want traction or mileage. I was getting about 43 mpg with stock tires but they were crap and car was unstable on wet roads expecially in windy conditions at high speeds. So I changed to 16" rims with proper rubber and mileage dropped to 34mpg. However, the car was stable
