The post on the door states all tires should be at 33psi, when i measured the pressure, its at 36psi. I assume this is what the dealer inflated it to when I got it since I first measured the tire pressure 2 weeks after I purchased the car. Should I leave it like that

 

It's entirely up to you. At 36psi you will get slightly better gas mileage, but your tires will wear a tad quicker. At 33psi you'll get better ride quality and slightly better handling. Personally, I keep mine at 33psi.

 

If you have OEM wheels follow what the door sticker advises for the best ride
and wear.

 

Thanks, I will put it at 33psi

 

This may actually just be a question of when you measured them; were the tires hot or cold? I keep mine at 34 cold, which means they probably get up to 37 or so while driving. Always measure cold, because temp differences can be significant - if you fill them to 33 psi hot, they'll be much too low.

 

I measured them when cold as instructed in the manual

 

I measured mine cold at like 38psi a couple weeks after buying the car. I just dropped them down to 33psi. I would never go more than 2psi above the door sticker, personally.
