The difference between tracked and wheeled is huge.
The biggest difference is ground pressure.
Tracks greatly increase the surface area under force.
A 72 ton M1 Abrams tank has a ground pressure of about 15 PSI. A standard passenger car weighing maybe 2 tons, has a ground pressure of 30 psi. A stiletto heel has a ground pressure of about 471 psi.
The area used to support a M1 Abrams tank is measured in meters, the area used to support a passenger car is measured in centimeters, and the area used to support a stiletto heel is measured in millimeters.
The bigger the area used to hold it up the weight of a object from the ground, the lower the ground pressure. The lower the ground pressure, the softer the ground could be and still allow a heavy object to be supported.
