West - I am hesitant to comment again on this topic, but after talking to some tire folks I felt it important, if for no other reason than your safety. I was told in no uncertain terms that inflating a tire to significantly above the tire manufacturer's rated maximum pressure can be very dangerous, in part because you've exceeded the design loads for the cord and fabric plies (and perhaps the rim itself) and ultimately cord or ply separation may occur with potentially catastrophic consequences. Of course do as you wish but I'd feel better about this if you discuss this with a technical rep of the tire manufacturer.

I appreciate your concern, both for me and fellow enthusiasts. The advice I've been taking came directly from the tire manufacturer owner, also a super-big-time old-car enthusiast, engineer, and one who did a lot of touring at high speeds. I will not mention his name.

I completely rebuilt the front end of my car, shocks, springs, etc. There is absolutely no wander, except in severely deep ruts, in which case I automatically slow down or change lanes. With a tight rebuilt front-end, even if it does wander, it is easy to keep under control. There is less heat build-up at the higher pressure, and since I drive 70-75mph on the freeway, I am more confident in the tire than if it were at 25psi.
