for my 03 rx300...i noticed that the recommended psi is listed at 30 for all 4 tires.

is this what everyone is using? if not...what is the ideal psi for the rx300?

btw...i have the bridgestone dueler (either h/l or h/t...not sure) tires. i requested these over the goodyear integrity tires.

in other vehicles...i usually run 2 psi over the recommended...but that's on cars. never owned a suv before.

please help!

The book says 30psi.
The doorjamb says 30psi.
I run 30psi, cold.

I use 34 front and 32 rear and feel great.

seeing that you're on the east coast and that its getting pretty cold here now, you should make sure that you put in the right amount of air.

the tire pressure usally drops about 1 psi per 10 degrees of temp change. so if it gets colder here on the east coast youll have to increase the psi in your tires even more than it is now.

I run 31-32 psi x4 cold. i just upped added more air (to get it back to 31) a few days ago since the temp dropped to about 18 degrees here in the mornings.

for some reason leaving it at 30 makes my tires look like its running low on air??

thanks for the advice. and yes...it's getting pretty cold in the east coast.

i haven't checked since i picked up the rx on saturday. i was assuming that the dealer put in the proper amount of tire pressure. i'll probably check and make sure tomorrow.

i'm thinking 32 psi is a good starting point for me. i like it to handle a bit better. i can withstand the harsher ride. but how harsh can the rx be? hehee.

I keep mine at 30~31psi cold so that it never exceeds the max pressure (35psi) after long periods of driving. I suggest following the book/sticker.

'Up' here in Mexico City at 8,000 feet, I put 33 front, 33 rear. I tried 30/30, and just too soft. Plus gas is really expensive. Does get cold this time of year 40s/50s.
