A New French Tire

A new bicycle tire has just been devised by M. M. (erard, city eng-ineer of Bordeaux and Picón, whichis intended to do away with the defects oí all othor tires. It consists in substance of a thin rubber tube whose inner surface is intersected by rubber disks perpendicular to it and placed close to one another; disks and surface are all moulded in one piece. The disks are thicker at the circumference than at the center, to prevent the tube from sinking into the interstices between supports, and they are made eccentric so as to distribute the resisting power of the surface without increasing the weight of the tire. They divide the tire into a very large number of air chambers, perfectly independent of one another! so that if one is pierced the others arè notaffected. These add to the elasticity of the tire, and do not need to be filled with compressed air. The motion is as easy as that of the best pneumatic tires, while the accidents to which pneumatic tires arj subject are done away with. The tire can be applied at once to all rims for solid or hollow tires. For pneumatic tire machines some slight but inexpensive modifieation of the rim will be necessary.
