Goodyear's Assurance ComforTred technology provides a smooth, quiet, comfortable ride to luxury or passenger coupes and sedans. The super-absorbent layer between the tread and belt insulates against vibrations and impacts. This special layer between the tread and steel belt provides an average 20% more cushion than standard passenger car tires. Constructed for long tread life and excellent all-season handling. Densely packed tread blocks provide a smooth and comfortable ride. PermaBlack compound in the tire preserves a new tire appearance throughout tread life.
