Front/Rear Tire pressure Question

After searching several posts on tire pressures, I noted that people were either running equal pressures for the front and rear tires or a few pounds more pressure in the rear.

Is the greater rear pressure used to overcome the infamous 911 oversteer at the limit during DE or race conditions?

Would it not make sense to run a little higher pressure in the front tires "FOR STREET USE" to compensate for the initial understeer conditions one finds with street driving in the 911?

The basic rule I learned during my karting days was: less pressure = looser and more pressure = more grip when trying to create a balanced kart.

What is the expert take on this?

Thank you.

Mike

My take is that the increased pressure in the rear gives the rears a bit more "grip" and they will be less likely to swap ends. Softer rears (than the fronts) will make the back really loose.

I think the pressures recommmended were not for track, but rather for street to input a little understeer to add a margin of 'safety' for the general public. Porsche was covering it's rearend.
