I've got
Cupra with 235/35/19, according to the specs it should be when not heavy loaded with 36 psi back 39 psi front and that what I did for year and a half, as a robot.
After I went to tire
shop to swap my front and back tires (~20K Km), apparently I've found that the front wheels were almost slicks (back ones were ok), so the guy in the tire
shop told me to put a bit less, and that what I do no - front gets 36 psi, rear gets 34 - a bit softer behavior, much much better grip, hope the tires will live longer too.
