33 is the right number. Trust the engineers that designed your car. They put more air in the tires at the factory in case it looses some during transport and storage. The dealer is suppose to correct it before delivery.

It's more because they are transported on top of car truck carrier platforms, and they want to minimize the sway during transport. It's not meant to be actually driven like that.

...saying that that's what Toyota recommends. My manual says my 19" should be filled to 33 psi. The sticker on my driver's door says 33 psi.

Toyota recommends what's on the door sticker and in owner's manual. He is a moron.
Some people think that, inflating the tires more, will give better fuel economy. Reality is that, after a certain point, there is very little reduction in tire rolling friction. That point is about what manufacturer tells you.
If you go above that, you won't decrease significantly the rolling friction.
You will, however, increase the road shocks transmitted to suspension components and body of the car. That will lead to accelerated wear on those suspension components and increased operational costs (to fix those earlier).
Also, that decrease in rolling friction comes with another safety penalty - road grip is diminished. Braking takes longer, lateral skidding in curves increases (and wear on tires), chance of losing control basically increases. Sure, the Traction Control will try to help against that, with some differential braking, but that braking action, to control the car, is actually decreasing the gas mileage. So, we're in a worse situation than if we follow the manufacturer's recommended tire pressure.
Those Toyota engineers were not dumb.

 

Im not that smart but since you changed rims does that not mean that your psi can change as well? I do want to know since i wanna downsize my rims from 19 to 17. Does the psi still stay the same?

 

Tires and rims will impact your recommended psi. The door jam sticker is what is recommended for the OEM tire you got. For example, the Rav4s with the 19 inch rim and OEM Toyo Open Country recommend 33 psi while the Rav4s with 19 inch inch rim and Yokohama and Michelin tires recommend 35 psi. In this example, just having the different OEM tire but the same rim size impacts the recommended psi by 2 psi.

That's technically not true, brand itself doesn't matter...
If it was, the DOT would have required Toyota to put that brand on the sticker, besides the size of tire.
However, besides the size, that tire size description on the sticker also has the speed and load rating. Those are sufficient to fully describe a tire.
If the manufacturer installed same sizes, but different speed and load rating tires, in my experience they all will be listed under the sticker. And yes, in that case there might be different pressures listed for different speed and load ratings.

Still, IMO the sticker has to be obeyed, not whatever Internet people feel like it would "work".

 

When you change the tire, you need to replace them with ones with the exact specs. I was offered, for one of my cars, a few years back a tire with the same "size" but a lower load rating. I accepted it not knowing better, and I found out that that set of tires were looking "deflated" at normal PSI. Even at higher PSI it was still not looking "right".

Different wear rating, speed rating, yeah not many people are going to do that. Especially if you want to upgrade to a better tire than the weak oem tires. The Michelin crossclimates are popular here, those are much different than the oem tires. The only way you’ll get the exact same specs is with the same exact tire.

 

Keep in mind, Toyota has different tires for the Rav4. You can win the tire lottery and get the Michelin Primacy which have a much better wear rating (almost twice that of the Yokohama) and ride in comparison to the Toyo or Yokohama. I wouldn’t recommend anyone with the Toyo or Yokohama tires to replace with the same ones.
