SYSTEMS AND METHODS FOR TIRE TREADWEAR SENSING

Disclosed are various embodiments for sensing wear of a tire tread. A tire comprises an innerliner, a plurality of belts layered adjacent to the innerliner, a tread adjacent to the plurality of belts opposite the innerliner and a treadwear sensor positioned in the innerliner. The treadwear sensor comprises a base plate on an interior side of the innerliner and a tube extending from the base plate through the innerliner and the plurality of belts to a first wear depth in the tread. When the tread is worn to the first wear depth, an end of the tube is exposed through the tire.
