Settng tire pressure to load is a matter of getting the proper tire to road contact patch. The reason those who have used the tire manufacturer's tables feel a more stable ride is a tire overinflated for load has less contact with the road surface, actually overheating at the contact area, causing higher center tread wear and less side to side grip.
Silver, this is exactly what I did (except for adding the 5psi to the 75psi). In my op, I just wanted confirmation, because 75 psi sounded low. To all of you with knowledge and the willingness to share it--Thank you.
For those who don't know and don't care that they don't know--there are none so blind as those who refuse to see.
Revised solution: 110 for steer and 85 for everything else. I just can't bring myself to go to 75 or 80 (at least until the Michelin man calls on Monday).
