Milton Tire Tread Depth Gauge 0–1" Box of 10 — Aluminum, 1/32" Graduations

The Milton 448 Tire Tread Depth Gauge is a compact, aluminum tread-measuring tool calibrated 0–1" in 1/32" increments, sold as a box of 10 for consistent, repeatable tire inspections.

Checking tire tread depth quickly and accurately matters for safety and vehicle performance. The Milton 448 offers a simple mechanical solution: a round aluminum indicator bar that slides to show precise depth readings, a pocket clip for easy carry, and a compact form that fits into automotive tool kits or service bays. Made in the USA and supplied in a box of 10, this gauge is built for shops, fleet managers, and DIYers who need reliable, repeatable measurements without electronic calibration or batteries.

How precise is the Milton 448 at measuring tread depth?

The Milton 448 reads from 0 to 1" using clear 1/32" markings so you can see small increments of wear. Because it’s a simple mechanical indicator, the scale is easy to interpret under shop lights and doesn’t require setup.

• Calibration range: 0–1" (0 to 25.4 mm)
• Graduations: 1/32" (≈0.8 mm) increments for fine readings
• Visible analog scale—no batteries or electronics
• Repeatable readings when used perpendicular to the tread

How do I use the gauge during a routine tire inspection?

Place the Milton 448 perpendicular to the tread groove and slide the indicator until it contacts the bottom of the groove. Read the depth where the indicator aligns with the engraved scale; repeat at multiple points across the tire for an accurate assessment.

• Hold tool square to the tread for best accuracy
• Take measurements at inner, center, and outer grooves
• Compare readings to manufacturer or regulatory limits
• Wipe clean after use to prevent dirt from affecting readings

What makes this model suited for shops and fleets?

Sold as a box of 10, the Milton 448 is practical for teams that need multiple gauges on hand. The robust round aluminum indicator resists bending and the pocket clip keeps the tool accessible during inspections, speeding up workflow in busy environments.

• Box of 10—stock multiple technicians or service bays
• Durable aluminum construction for repeated use
• Pocket clip for hands-free portability and quick access

How should I maintain and store the tread depth gauge?

Minimal care keeps the Milton 448 accurate: clean debris from the indicator and scale after each use and store in a dry place to avoid corrosion. The pocket clip helps prevent loss, and occasional inspection of the engraved markings ensures legibility over time.

• Wipe off grit after inspections to protect the scale
• Store in a toolbox or pouch to prevent scratches
• Check markings periodically for wear or damage
• No batteries or calibration equipment required
