The air pressure of your car/bike tires doesn't matter - all tires could be flat. Try comparing (vehicle weight + your weight) / (vehicle contact surface area) where vehicle is either your car or your bike.
- tzs 4y agoFor tires that support the vehicle via air pressure in the tires, contact area is roughly weight supported by tire / air pressure in tire [1].

- ars 4y agoWhen the tire is flat it is being supported by the sidewalls and by the wheel. And if you notice the contact patch of a flat tire is much larger. The ground pressure of any vehicle is almost exactly equal to the psi. With the exception of force carried by the sidewalls.
