Abstract:
A tube tire, the tire including an outer ground engaging portion, a pair of sidewalls integrally formed to opposite sides of the outer ground engaging portion and extending radially inward, and radially inner first and second edges of the sidewalls being adapted to abut against first and second rim flanges of a wheel, said tube tire including a tube comprising:walls forming a toroidal shape, said tube being adapted to fit inside a space formed between the sidewalls and adjacent to a radial underside of the ground engaging portion, said walls of said tube having a wall thickness; anda first reinforced member positioned alongside said walls of said tube along a first circumferential strip, said first reinforced member creating an overall tube thickness across said first circumferential strip which rises from said wall thickness to an increased thickness and then declines to said wall thickness, wherein said first reinforced member is so positioned on said walls that upon the ground engaging portion of the tire deforming toward the radially inner first edge of the sidewalls, said first reinforced member will overlay the first rim flange of the wheel; anda second reinforced member positioned alongside said walls of said tube along a second circumferential strip, said second reinforced member creating an overall tube thickness across said second circumferential strip which rises from said wall thickness to said increased thickness and then declines to said wall thickness, wherein said second reinforced member is so positioned on said walls that upon the ground engaging portion of the tire deforming toward the radially inner second edge of the sidewalls, said second reinforced member will overlay the second rim flange of the wheel.
