Example Ground Pressures
All examples are approximate, and will vary based on conditions
Hovercraft: 0.7 kPa (0.1 psi)
Human on Snowshoes: 3.5 kPa (0.5 psi)
Rubber-tracked ATV: 5.165 kPa (0.75 psi)
Diedrich D-50 - T2 Drilling rig: 26.2 kPa (3.8 psi)
Human male (1.8 meter tall, medium build): 55 kPa (8 psi)
M1 Abrams tank: 103 kPa (15 psi)
1993 Toyota 4Runner / Hilux Surf: 170 kPa (25 psi)
Adult horse (550 kg, 1250 lb): 170 kPa (25 psi)
Passenger car: 205 kPa (30 psi)
Wheeled ATV: 240 kPa (35 psi)
Mountain bicycle: 245 kPa (40 psi)
Racing bicycle: 620 kPa (90 psi)
Note: Pressures for Man and Horse are for standing still. A walking human will exert more than double his standing pressure. A galloping horse will exert up to 3.5 MPa (500 psi). The ground pressure for a pneumatic tire is roughly equal to its inflation pressure.

Famous quotes containing the words ground and/or pressures:
“We used to think that revolutions are the cause of change. Actually it is the other way around: change prepares the ground for revolution.”
—Eric Hoffer (1902–1983)
“The pressures of being a parent are equal to any pressure on earth. To be a conscious parent, and really look to that little being’s mental and physical health, is a responsibility which most of us, including me, avoid most of the time because it’s too hard.”
—John Lennon (1940–1980)
