Use this table as a guide during your monthly walk-around. Start at the driver's front tire and move clockwise around the vehicle to ensure no wheel is missed. Mark each item as 'Pass' only if it meets the criteria exactly.
If you identify multiple wear patterns (such as cupping and edge wear), it often indicates a combination of suspension wear and alignment issues. Address these promptly to avoid premature tire failure.
