IMO the tire pressure posted on the door is a compromise between a ride comfort & reasonable rolling resistance (gas mileage), with the scale tilted towards comfort, hence the low pressure recommendation. I don't think the factory really cares about tire life or performace on the Forester...
The tire pressure will vary between tire brands. I'd suggest starting with the pressure that felt right on your previous tires. I'm running Toyo Proxes 4, 235/50-17, 36/34 (front/rear pressure). After playing around with different pressure combinations, this is what feels right on my ride. A higher tire pressure makes my ride susceptible to bump steering on rought roads & too low pressure makes my side walls roll too much...
