I have a 2015 scion and got all black Rims 18inch should i use the PSI from the Toyota manual or raise the PSI since the rim seems heavier then my previous ones .
the rims are the same says as my previous factory ones
?
The correct pressure is written in your owners manual and on the drivers door post. The rims have nothing whatsoever to do with the correct pressure you should use. That is based on the weight of the car and cargo. Use what Toyota recommends and nothing else.

The weight of the wheels has nothing to do with it. The folks that install the tires will put the correct psi
