Groupe Michelin continues the development of its airless radial tire, the Tweel. The company announced two new tread patterns for skid steers plus an OE fitment with John Deere & Co.'s ZTrak 900 Series of zero-turn commercial mowers. The 12N16.5X Tweel SSL All-Terrain has a deep, open tread for off-road applications. The heavy-duty poly-resin spokes are designed to self-evacuate in muddy conditions. The 12N16.5X Tweel SSL Hard Surface tire features a smooth tread and provides longer wear life on pavement and asphalt. The Michelin X Tweel Turf will be OE to replace a standard 24x12x12 tire on select John Deere commercial mowers. It will be available on the 54-, 60- and 72-inch deck sizes.
