## What is Wheel Changium?

Give a tread gauge a proper paper trail: record the rubber that matters, point by point and rotation by rotation, with a precise millimetre log built for real-world vehicle work.
Set up vehicles, wheel positions, and seasonal sets, then choose Quick, Standard, or Advanced measurement maps for each inspection. Capture inner, crown, and outer tread depth, compare left against right, steer against drive, and set against set. Pattern flags surface shoulder, center, stagger, and cupping changes only when differences move beyond normal gauge variation, while a twelve-week timeline reveals how the tread profile is actually changing.
Go deeper with eight measurement techniques, inspection checklists, service events, rotation records, reminders, and editable warn/scrap thresholds. Create projects around vehicles or tire sets, connect measurements across inspections, and keep each casing tied to its own history. From the first gauge reading to the next rotation and the approach toward the legal tread floor, turn scattered measurements into a disciplined inspection record.
