SAFELIFE Digital Tire Tread Depth Gauge — Zeroable 3‑Mode (0–25.4mm/0–1in), Large LCD

SAFELIFE Digital Tire Tread Depth Gauge is a pocket-sized digital gauge that measures tire tread depth in millimeters, decimal inches, or fractional inches for quick, precise checks on cars, trucks, motorcycles and SUVs.

Keep vehicle traction, safety margins and legal tread limits in view with a compact, easy-to-read instrument designed for DIY drivers and professional technicians alike. This SAFELIFE gauge reads 0–25.4 mm (0–1 inch / 32nds), offers a large LCD, a zeroable probe for calibration, and automatic shutoff to preserve the included CR2032 battery. Its small footprint fits in a glove box or tool pouch, making routine checks simple and fast.

How does the SAFELIFE gauge deliver accurate readings?

The gauge combines a finely machined probe with digital electronics and a zeroing feature so you can calibrate it against any flat surface before measuring. The screen displays measurements clearly and the depth bar provides a backup visual scale if the battery is depleted.

• Measurement range: 0–25.4 mm (metric) / 0–1 in (SAE, including 32nds)
• One-touch mode switch: millimeters, decimal inches, or fractional inches
• Zeroable at any position for exact relative readings
• Large LCD and depth bar for readability and battery-down fallback

What types of vehicles and situations is it suitable for?

The SAFELIFE gauge works on most rubber tire treads and is appropriate for cars, SUVs, pickups, trucks and motorcycles. Use it for routine maintenance, pre-trip inspections, or to check brake pad wear when the pad surface is accessible.

• Designed for passenger cars, light trucks, motorcycles and vans
• Useful for spot checks at home or on-the-road inspections
• Compact design fits a pocket or tool pouch for mobile use
• Can assist with brake pad wear checks where accessible

How do I get consistent results on uneven or worn treads?

Position the base flat across a tread groove so the probe drops fully into the lowest point for that groove. Zero the gauge against a reference surface if you need relative measurements, and take readings from multiple grooves to average for better accuracy.

• Seat base flat across the tread for correct probe travel
• Use zeroable function before a measurement for consistency
• Measure several grooves and average values for an overall picture
• Refer to the depth bar when battery power is low

What maintenance and battery care should I follow?

The device includes a CR2032 battery and power-saving auto-off after about five minutes of inactivity. Store the gauge dry, wipe the probe after use, and replace the battery when the display dims or the depth bar becomes primary.

• Auto-off preserves battery life; manual off not required
• Replace CR2032 when display brightness fades
• Keep probe clean and free of debris for accurate contact
• Store in a dry place and avoid heavy impacts to the probe

Who is this for? The SAFELIFE Digital Tire Tread Depth Gauge is for motorists, fleet managers, mechanics and motorbike riders who want a fast, inexpensive way to check tread and safety margins without guesswork. It’s ideal for anyone who performs their own maintenance, checks rental or used-vehicle condition, or wants a simple tool to confirm legal tread limits and driving-surface safety. Use it during seasonal checks, before long trips, or whenever you suspect uneven wear. By combining a clear LCD, a fallback depth scale, three display modes and a zeroable probe in a pocketable housing, SAFELIFE gives practical accuracy for everyday safety checks.
