[b]Maximum Inflation Pressure

A tire's maximum inflation pressure is the highest "cold" inflation pressure that the tire
is designed to contain. However the tire's maximum inflation pressure should only be
used when called for on the vehicle's tire placard or in the vehicle's owners manual. It
is also important to remember that the vehicle's recommended tire inflation pressure
is always to be measured and set when the tire is "cold". Cold conditions are defined
as early in the morning before the day's ambient temperature, sun's radiant heat or
the heat generated while driving have caused the tire pressure to temporarily
increase.
That's great that you've talked to tire engineers. I'm afraid that you have either misunderstood what they told you, or they are giving you bad information. (Knowing the engineers that I know, I expect the former is true.) I also doubt that Tirerack, a company in the business of selling tires, would have missed that engineering gem. To me, they explain it correctly, in as plain English as possible.

Ford Motor Company determined the proper inflation pressure of this car with its weight in mind, and they tell me it's 32 psi cold. On a 205/55ZR16 tire with an "A" Temperature rating. Which is exactly what I have. I know, Ford and Firestone screwed up the Explorer settings. Besides the politics involved (Ford wrote a poor tire spec, Firestone delivered a subpar tire, whatever), the tire rating situation on the SVT Contour is completely different. Niche sports car vs. high profit high volume truck.

But if I was going to lose a tire, this past week would have been it. Have I mentioned the large amount of tire blowout debris fields I dodged last week? Short of driving my car to the Desert Southwest, it was easily the hottest conditions the car is ever going to see on any long drive.

However, I don't have a completely closed mind on this. PM me the tire engineer's email addy and I'd love to hear it right from him/her.[/b]
PA, you said that the pressure rating is for a 205/55 tire. My tires came on cougar wheels and are 215/50, I thought that eas the same size as SVT's?? or just e1's??
