Same tire, same rock, but very different air pressures. One has 35 psi (the maximum)(top image) and the other about 6 psi (bottom image)—a good pressure for rockcrawling with beadlock wheels. This demonstrates how airing down increases the contact surface of a tire while off-road. The image with 6 psi shows the tire enveloping the rock while the image with 35 psi shows the tire barely balanced on top of the rock. Airing down too low can be dangerous since tires can slip over the wheels safety bead and rapidly deflate. Even on-road, it’s probably not necessary to run the maximum tire pressure unless you are approaching the maximum load rating with your vehicle when fully loaded.
