Wheel and tire assembly for recreational vehicles
First Claim
1. A low pressure tire formed as a substantially torus-shaped member, said tire comprising:
- an inner diameter surface for engaging a tire supporting rim;
sidewall portions;
an outer diameter surface for contacting a support surface;
transverse protrusions disposed on the inner diameter surface and extending in a direction of an axial width the tire; and
a sealable opening located in one of said sidewall portions for inflating the torus.

Abstract
A wheel and tire assembly for recreational vehicles, such as mountainboards, motorized carts and pedaled carts is provided. The tire comprises a tire made of substantially inelastic material that will not stretch under a load. Thus, the tire will flatten under a load to provide a high level of traction on soft and irregular surfaces, as well as on hard and flat surfaces. The tire includes protrusions on its inner diameter surface for securely engaging the wheel. The wheel includes a rim that supports the tire and includes protrusions for engaging the protrusions of the tire in an interdigitating manner. The interdigitating engagement of the protrusions on the tire with the protrusions on the wheel prevents slippage and rotation of the tire relative to the wheel. The wheel also includes support flanges that extend radially inward from the rim in order to protect the tire from damage as the tire deforms under a load.

21. A wheel and tire assembly comprising:
-
a tire formed as a substantially torus-shaped member, said tire comprising;
an inner diameter surface for engaging a tire supporting rim;
sidewall portions;
an outer diameter surface for contacting a support surface;
first transverse protrusions disposed on the inner diameter surface and extending in a direction of an axial width the tire; and
a wheel comprising;
a hub for receiving an axle;
a tire supporting rim connected to said hub, the tire supporting rim including a cylindrical center section, conical portions extending from opposite sides of the cylindrical center section and rounded lips extending from said conical portions;
tire supporting flanges extending radially inwardly from said rounded lips; and
second transverse protrusions disposed on an outer diameter surface of the rim and extending in a direction of an axial width of the wheel, wherein said first transverse protrusions and said second transverse protrusions engage each other in an interdigitating fashion, and wherein said tire supporting flanges are adapted to support said sidewall portions as side torque is applied to said tire. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
