How old were the tires when owners reported the problem?

2 to 3 years is the largest group at 6, out of 7 complaints (a small sample, so treat it as a hint).

Age of the tire when the owner reported the problem, from the date code molded into the sidewall. 2 to 3 years: 6; 6 to 7 years: 1.

A tire's age is printed on its sidewall as a four-digit date code (week and year): check yours.
