Porker:
 

I have them at 2.0F-2.3R cold now, too much?

I run for street driving 1.8 and 2.1 . They are good up to 2.0 and 2.3 on the street . They heat up pretty easily in summer so you are quickly over the ideal running pressure .

I would not want to drive with any pressure above 2.1 and 2.4 on the street  when tire are hot .
