super mario Posted May 3, 2008 Posted May 3, 2008 Hi, Just wondering what everyone has their tyre psi on their yokohama's which came with the car (although I believe some models came with Dunlops) and whether its worth plumping them up a bit due to the extra weight on the 450h
super mario Posted May 6, 2008 Author Posted May 6, 2008 I have the dunlop run flats, I run them at 33 psi. Thanks for the reply G man - I was also wondering everytime you change the tyre pressure to do you have to initialise the tyre pressure warning system (switch under the dash)? ( my manual says 38psi back and 36psi front for tyre pressure for above 100mph and 35 front and back below that - but thats not specific to yoko's)
The G Man Posted May 6, 2008 Posted May 6, 2008 No you dont need to initialize the TPMS when you change tire pressure, it should have enough play in it that the alarm wont go off. I cwould check your driver door jam to see what is the recommanded PSI for your tires.
