What is the minimum remaining tread depth required at the specified measurement points for an ordinary passenger-car tire in Maine?
Correct answer: 2/32 inch
Why
At the required measurement points, at least 2/32 inch of tread design must remain. Measure in the major grooves as the statute specifies. Adequate depth does not excuse exposed cords, dangerous bulges, structural cuts or other unsafe tire conditions. Also check pressure when the tires are cold.
