Car Tire Depth Gauge — metal construction, double scale, accurate to under 0.1 mm Key benefits Know when tires are unsafe: quickly identify excessive tread wear before it becomes a driving hazard. Maintain vehicle performance: accurate depth checks help preserve traction, braking, and fuel efficiency by indicating when tires need replacement or rotation. Save time and money: spot uneven wear early to avoid premature replacements and improve service decisions. What it does Measures tire tread depth precisely to help you assess wear and determine whether tires meet safety or manufacturer requirements. Doublescale readout makes measurements easy to read and interpret at a glance. Metal construction provides durability for repeated use in workshops, garages, or roadside checks. Important attributes Material: metal body for longlasting use and reliable measurement. Scale: double scale for straightforward reading (two parallel measurement scales). Accuracy: precision with an error margin of less than 0.1 mm. Intended users: car owners, drivers, and maintenance professionals who prioritize safe, wellmaintained vehicles. Compatibility: designed to measure passenger car tire tread depth. Practical use scenarios Pretrip safety check: test tread depth before a long drive to confirm tires are safe for wet, snowy, or speed conditions. Routine maintenance: use during tire rotations or inspections to track wear patterns and decide when to or rebalance tires. Usedtire or vehicle : verify advertised tire condition when inspecting a used tire or buying a secondhand vehicle. How to use (simple) Insert the gauge into the tire tread groove. Read the measurement on the double scale. Compare the reading to the vehicle or tire manufacturer's recommended tread depth and local safety standards. Reliable, precise, and built for repeated use — a straightforward tool for anyone who wants accurate tire wear information and safer driving decisions.
