No, I mean that a P235R15 tire inflated to 22 pis is rated to safetly support the load of a fully laoded Explorer. There are industry standards for P metric tires. All tires of a given size and type should meet the minimum industry standards no matter how they are constructed. The "evil" tires installed on Explorers were P235/75-15 S105 Tires. The industry standard load inflation table for this tire size follows:
Cold Inf. Pressure Load
20 1543 23 1653 26 1753 29 1852 32 1940 35 2028For use on "light trucks" the laodvalues for P series tires are derated by 10%. So at 26 psi, the tires on an Explorer should have been suitable to support a load of 1,578 lbs. This is a tire industry standard, not a Ford standard, or a Firestone standard. A P235/75-15 Tire inflated to 26 psi is rated to carry 1,578 lbs at it's maximum rated speed when mounted on a light truck. Since the Explorers used "S" rated tires, the maximum safe speed is 112 mph. Explorers are limited to 105 mph top speed by the vehicle's PCM.
I've seen vehicles from all sort of manufacturers with the wheels tucked in like the one in the picture. I just saw a Generation 1 Tundra last week on the side of the road with the wheel tucked in. The Tundra probably was the victim of a ball joint failure. The picture you posted is highly unusual, I don't think it is a "typical" failure. I would suspect the vehicle had been in a prior accident or that the upright had been damaged in some way.
Actually the Explorer's front suspension was completely redesigned in the mid-90s (1995), not the late 90s. The strut bushing you are whining about went away when the twin I beam front suspension was eliminated in 1995.
How can you say that? Explorers that came with Goodyear tires from the factory had no unusal problems with tire failures. And since the defective Firestones tires have been replaced, you never hear of any problems with Explorers and tire tread separations. Even back before the Firestone tire recall, Explorers did not have a particularly high driver death rate due to rollovers. The driver death rate due to vehicle rollover for the following 1994 -1997 CARS was higher than for
