Hey, just brought my brand new 2011 (red) Prius home. Looks great in my drive. OK, on my 2005 I had factory tires and at that time people here said to run tire pressure at 42 front / 40 back to get the best mileage. My 2011 has P195/65R15 89S Yokohama. What are those of you in the know running your tire pressure at on your 2011? Also, any other tips for mileage. Dealer told me I only had to change oil every 10,000 miles now. Still plan to rotate tires every 5,000. Thanks for any insight. Prius forever.
