Answer:
maturity
Step-by-step explanation:
Based on the information provided within the question it can be said that the tires are in the maturity stage of their product life cycle. This is the longest stage in the product life cycle in which the introduction and growth stages has already passed and the product advertisements have minimal impact on sales since people have already seen the product. This seems to be the case since Goodrich has sold it's tires for more than a hundred years and only focuses on short term marketing.
