<p>This is a new rim with hollow spokes for vehicles in general in which the hollow interior of the spokes communicates with the rim channel within the tyre. The greater surface area of the rim between the internal air of the tyre and the external air makes greater cooling of the internal air and the wheel in general possible, the larger volume of air dampens impacts better and makes it possible to fit shallower tyres to the rim. <IMAGE></p> |
