Introduced at CONEXPO-CON/AGG, the XDR2 tire is available in a 27R49 size. Additional sizes will be available later in the year. In addition to the increased tread life, the XDR2 tire also delivers up to a 10% thicker undertread between the protective plies and tread base for better cut and impact resistance. With a new self-cleaning tread pattern, the XDR2 tire combines full-depth blocks, a 13% larger central lug (compared to XDR tire) and the new non-directional design to provide increased protection against aggressions and cut separations. The evolving tread design provides an increased contact patch as the tire wears, while sculptured cooling vents help keep running temperatures low.
