i have the falkens 512 (235/45zr17). i was wondering what the tire pressure should be, whether they are the same as the stock potenzas or if they have a different psi. thanks for your help.

 

tire pressure dependent on the tire size and car weight ... it doesn't depend on the tire brand So, if we are running stock size, then it's the psi indicated in manual .. if not you need to do some math to derive the psi.

 

0 psi. Take them off and put on some decent tires. If you must, you can get the confort and handling of a Lincoln Clown car at 35 psi.

When I had the 512s on, I got them from 40 up to 47 psi trying to fix their nasty squirmish tendencies, without any success.
