-What Tire PSI is your Prius running?

I get the longest tire life at 40 PSI Front 38 PSI Rear.

 

~38psi all around.

 

I run 42 PSI front and 40 PSI rear in my Prius tires which are rated as 51 PSI Max cold.

Ecopias ---> 47psi in front & 45psi in rear

 

My Volt and 1999 Insight stay between 50-60psi in the summer

Much better tire life

 

i run 20 at each corner. the traction, braking and handling are amazing, and it is your fathers oldsmobile.

 

ONLY until one of them explodes because of chronic over-inflation.
Stupid is the only word that comes to mind.

 

Got 80,000 out of the OEMs that came on the car, helps when the sidewall is rated over 50psi

 

35 PSI Front
33 PSI Rear

I have tried higher pressures up to 44/42 and found no significant improvement in MPG over a couple of tire cycles. Tires had to be scrapped early due to the centers wearing out before the sides. So went back to the Toyota recommended pressures above. Tires last much longer. Traction and braking are good, too.

 

If so, then Wayne Gerdes and his cadre must have considerable experience with these explosions.

 

36 psi all the way around.

 

Explain please.......or not.
Somehow I think it will not be useful information.
