Most tires have at least six wear bars, although tires with a rim diameter of 12 inches or less may have as few as three wear bars. Wear bars are a series of raised features in the bottom of the tire tread with a height equal to the minimum tread depth allowed for the tire, typically 1/16 inch.
Weekly Benefit Rate. The amount of unemployment benefits you may receive each week is your Weekly Benefit Rate (WBR). The amount will be 60% of the average weekly earnings during your base year period. The maximum amount may change each year.
Total earnings: The SSA determines the total amount you earned in the 35 years during which you made the most money, up to a maximum amount per year. The limit is adjusted for inflation -- in 1951, the limit was $3,600. In 2016, it's $118,500. If you worked fewer than 35 years, the missing years are counted as zero.
