Thanks for the formula and other info. The part about overinflation being a possible hazard is particularly informative. I had never heard that before and I think I will share it on other sites I visit just to add to their imformation base. Some hybrid vehicle owners are inflating their tires to ridiculous levels to maximize MPG and they may not know it can cause problems.

Goodyear's web site shows that my 215 Marathons will support my 3200lb TM at 40psi but I run 50psi. I assume 10psi over is OK since that's what TM recommends but 20 or more over could be detrimental. Am I right on that?
