use the sticker inside the door as a starting point. you can add 2 to 3 psi more than what's indicated. manufacturers indicate a figure/figures with some (rather big) consideration on ride comfort. mapapansin mo tread wear sa gilid.
i put 34/35 psi vs 32 psi on the door sticker. the RX350 is almost 2 tonnes, so tama lang 34/35.
there's no such thing as "33 psi standard", depende kasi sa sasakyan 'yan. i put +2 or +3 psi for better treadwear - 32 sa sticker, i pump 34/35. makes a difference to treadwear sa bandang gilid ng gulong.
'yung Gen 1 CR-V ko dati, 26 lang nasa sticker, but i used to pump 30.
also di naman sasabog basta-basta. there's a big gap between the pressure on the door sticker vs the tyre's maximum pressure. in my case, door sticker = 32 psi (210 kPa) vs tyre maximum 50 psi (350 kPa). that's for a Continental Ultra Contact 6 SUV.
