Hi guys. I changed my wheels from 16 to 19 inches, and now I'm not sure if the tire pressure should be the same as the one indicated by Honda. Thanks for any info regarding this situation.

Definitely re-calibrate the TPMS.

Uh... I think that you go with what Honda says based on the design of the car. I believe it'd still be 32-35 psi, though.

You follow what it says on the tire. Not sure if tpms was supposed to be reprogrammed.
WRONG!

How is this what people still think is true!?

Tire pressure since....oh i dunno....at least the late seventies has been inside the driver door jamb on the vehicle weight and tire safety sticker.

Please dont spread this kind of incorrect info. Some 16 yr old can read it and go out to his dry rotted set of nexen tires and jack them up to 50psi and cause a deadly pile up on the interstate...

the pressure imprinted into the tire is the absolute max it will hold before it can EXPLODE

he changed his wheels from 16 to 19.. that means he changed his tires as well... but hey if you think your right, thats fine by me. If some kid fills up his tires to maximum pressure (which would be 50 usually) then thats the kids fault. If you change your tires from factory. Then the sticker in the door means nothing anymore. Granted, most tires will be 35psi

I know im exaggerating the response, i just want the correct info to be out there and obvious.

35 psi is the go-to pressure for anyone unsure. There are many methods to find out what it should be but it's ultimately your decision within a 30-40psi range.

33 front/32 rear is the spec for the new Sport Coupe with 18" wheels. If you bought the Honda 19" wheels; I'm gonna' carefully assume that the pressures would be similar. And +1 for the TPMS calibration.

Thanks for all the answers. I went from 215/55R16 to 235/35R19. I have a Canadian version (Civic Sedan EX), so I don't have TPMS. Inside the driver's door, it says 32 psi, and I was trying to confirm if even changing the profile, that recommendation remains the same.

Generally you should stay close to the door sticker but you can deviate a few psi. I run 34/34 because it seems to give me a slight mpg increase. I also sometimes run a pound or two more up front. Something like 34/32 or 35/33.
