Illustrative remaining distance = max(0, current tread minus chosen threshold) / assumed wear rate × 1000.
Important: Never rely on this estimate to decide whether a tyre is roadworthy. Legal minima vary; damage, wet grip, age and uneven wear can require earlier replacement.
These are planning estimates. No vehicle safety certification or professional valuation is provided.
