True, it is winter, and I wasn't really going that fast. But they were at "operating temperature" for the winter. So I want the pressures at that temperature to be correct. Then when summer comes along I will re-adjust.

You sure? These are not race tires, just DOT-R compounds. The fronts are medium compound, rears are medium hard.
All the reports I heard from the track and autocross guys were that the A048s don't like too much pressure. Above 30 they reported them beign greasy. Some Lotus used 27/29 hot at the track.
Now that I think I have the clearance problem fixed I will try to scrub in the rear tires and if the understeer is still there I will drop the front tire pressures since I did not have understeer with the much lower pressures. And I will watch the tire wear to see if the rears have too much pressure. I think I was running them right about 28 or 29 warm before and the wear pattern was good. The shoulders are still there since I am not racing or autocrossing it, but the scrub goes to the little triangle marker.
