A low pressure radial ply tire (20) for light off-the-road use has tow radial carcass plies (22) oriented at a cord angle (CA) with respect to the Equatorial Plane (EP) from 65 to 85 DEG . The tire is not reinforced by a belt reinforcing structure to allow the carcass (22) to compensate within the footprint of the tire under varying conditions. The tread (26) is provided with a number of holes (38) having a very shallow depth and spaced uniformly across the tread surface to increase flotation and wherein the net-to-gross is in the range of 0.63 to 0.77.
