To date, tires in general were divided into two types: bias (diagonal) ply tires and radial tires. All conventional tires can be described as having a ‘U’ profile and complying with a few basic rules.
1The largest volume of air the tire can hold is defined by the envelope of the tire for its specific tire skin. An increase in air pressure, as a result of load or rise in temperature, may cause the tire to burst.

 

In all existing tires there is a correlation between air pressure and rolling circumference. The rolling circumference is calculated based on the loaded radius –the distance between the wheel center and the ground- so the bigger the load the smaller the radius and therefore the smaller the rolling circumference.

2There is a direct link in all existing tires between air pressure and lateral force handling ability – the lower the pressure the poorer the ability to maintain accurate steering, and eventually to keep the tire mounted on the rim of the wheel.
3A similar rule applies to the relationship between ride quality and side stability. The flexibility of the tire at low pressure allows for a smoother ride but at the same time jeopardizes the steering ability and stability of a vehicle.
4Reduced air pressure will result in a bigger footprint but at the expense of rolling resistance. Moreover, at a certain point the tire tread will collapse and buckle in, and although the footprint may seem to be bigger, the actual contact patch will be smaller.
5The entirely different design of the Galileo Wheel tire offers a solution to these problems. The tire has an ‘accordion-shape’ folding sidewall that allows the outer circumference to change its shape freely, and move about the wheel center in all directions. It maintains a safe, comfortable, stable ride without problems of steering and handling. Furthermore, while air pressure drops, the sidewall folds (does not collapse as in a standard tire) generating far less heat.
