Same as the old Integrity's, as high as your bottom can stand. But that's just me.

I recommend at least sidewall pressure. I left the dealership and stopped at the gas station across the street and took them to 51 front and 50 rear and drove to Virginia. I was surprised to find the pressure from the dealership at 39 rear and 41 front. No problems and it handled well. On our return trip, I drove through rain for about 150 miles including one torrential downpour that had the interstate traffic slowed to 35 mph.

MAX Sidewall on the Yokos is 44psi. I'm running 40/38. I reset Trip A and Trip B at last fillup. I reset Trip B again after bumping tire pressures 75-100 miles into the tank. Trip B reads about 1-1.5mpg higher than Trip A. At the initial inflation, I saw 60+mpg, but then my commute set in.

2010 Prius III with Navi:

I inflated my Yoko's to max sidewall pressure on all 4 tires, 44 PSI, when we purchased the car on 05/17/09.

No problem with handling, MPG is averaging over 51 MPG for 3,000 miles, based on gas pumped and miles driven.

I'm a bit confused.
It finally stopped raining here today so I had a chance to check the tires.
MY tires say "40 PSI max" the door label says 35/35!!!!!

they were not properly inflated in any way!
it's been cool here so i went 38/36.

where are you finding 44 pSI??

thanks!

Hmmm... My door label says 35 front/33 rear and the Max Load on the tire says 44 psi for the Yokohama Avid S33. Have you double-checked your numbers?

40 PSI max is for seating the bead to the rim. 44psi is the max cold pressure.
