Keep in mind that with many vehicles, the Load Range E tires can be run at lower than the full listed psi because they are lighter than than the rated capacity. This lets you vary tire pressure over a wide range to match the road, trail, and surface conditions. I'm running Load Range E 255/85R16 KM2 at just over 40 psi around town and the ride is pretty plush in the 80. If I have a long road trip planned I'll add a few more psi for better mileage. Airing down for the trail provides a substantially longer footprint
