Do Rokons really leave a track lighter than a mans foot print?
There are many variables involved in calculating ground contact pressure, including vehicle weight, load, attitude, and contact patch size which includes the variables, tire size, tire stiffness, tire pressure, soil condition, and others. Here is an educated guestimate: Force downward: rider, 200# + vehicle, 200 = 400lbs Contact patch size at 3psi inflation pressure: 6 x 8 x 2 tires = 96in sq Ground contact pressure: F/Area=400lb/96in sq = 4 psi By comparison, the 200lb man when on one foot, which he would be while striding forward, might have a contact patch of 32 in sq, depending on his shoe size, for a ground contact pressure of 6psi. The Rokon has the advantage of smoothly applied, low power, all wheel traction. They have historically been considered environmentally friendly, and have been used by the Forest Service and other government agencies for trail use.
