Wear bars are visible when tread depth is what?

Wear bars are visible when tread depth is what?

• A. 1/8 inch
• B. 1/32 inch
• C. 1/4 inch
• D. 1/16 inch

Answer: (D)

Wear bars are built-in indicators in the tire tread that show when the tread has worn down to the minimum safe depth. They appear as raised bars across the grooves and become visible when the remaining tread reaches the bar height. That specific depth is about 2/32 inch, which is the same as 1/16 inch. So when you can see the wear bars at roughly 1/16 inch of tread left, it’s time to consider replacing the tire, especially since performance on wet roads deteriorates as tread gets this low. For context, new tires start with much deeper tread, so these bars are a practical cue to replacement.
