I never paid much attention to the tpm but what psi should all four tires be for.the 19 inch bridgestones?

 

Isn't there a sticker on the driver's side door jamb and isn't on the tires themselves?

That being said, I think I've got mine at 34-35 right now. When the weather turned cold I started getting tire pressure low warning so I pumped them up.

I've been thinking of using nitrogen, but I understand it's $10/tire and they install green valve stem caps. Not sure how the green would go with the blue themed hybrid colors!

 

According to my tire gage I keep them just above 30 psi which keeps the sensors from going off and yet I don't get as harsh of ride or as much tire noise.

 

TP is shown on the drivers side door jam sticker. Believe the 19 " are 33 PSI.

 

it is 33 psi on the 18" tires and the 19" tires

 

Im pretty sure my door jam says 36psi but I could be wrong. The instrument cluster gauge reads 36-38 psi depending on when I check.

I had nitrogen on my 330 and didnt notice much of a different. I replaced the green valve stems with black ones, haha

 

Just Google nitrogen VS. air. Don't be fooled, dealers found another way to empty your pockets. Air we breath is 79% nitrogen. That small difference is a scam to your wallet. My car came with it and I won't be paying $8.00 per an adjustment anytime soon. What the heck is this BOTOX! There are plenty of credible scientists who state its all a scam. perhaps a car on a race track doing 180mph for several hours may benefit, even that is questionable. Safe your money! This is paying for high octane gasoline are the scams. Our gasoline is watered down with so many additives and yet engines keep running just fine.

 

i keep mine at 35 psi.

 

31-32 here.

 

Dealer pumps to about 35 psi even though this is higher than the recommended pressure listed on the door jams.
I believe pressure listed on tire sidewalls is max recommemded pressure or something like that.

 

Tire sidewall shows the max the tire should ever have, which is usually 44psi. IMHO it is best to have 35psi. Better fuel economy, and the tire pressure light will not come on.

 

The sticker on my 2010 RX 350 FWD made in 06/10 states 32 PSI all around for all loads. Pumping a few more in isn't going to make much difference, but if the ride gets choppy try cutting it back to 32 and see how it rides/handles.

 

I have 18s says 32 PSI on the door but I do not run that more like 35 all year round.

 

i have the 19" wheels on my 450h. when cold, the psis are all at 28. should i be concerned? i havent really check the psi when the car has been driven for a while.

 

28 is too low.
I like running with 31-32 for a softer ride.
