Answer 1

Air Filled Tires do two things. They add ride comfort and add traction. Both are accomplished by allowing the tire to deform as it goes over terrain. By making a tire solid, you are removing the ability of the tire absorbing impacts and making it impossible to spread the weight across a larger area of the tire.
