Tire Life Forecast Calculator
Project distance to an entered removal tread from observed tread loss and distance for multiple tire records.
What would you like to do next?
Extend measured tread wear into a visible distance forecast
Enter tire identifier, starting tread, current tread, distance used and an entered removal tread. The calculator derives observed wear per thousand kilometres and extends that average rate to the remaining tread. Records with no measurable wear remain identified as insufficient rather than receiving an invented forecast.
Inspect condition instead of relying on linear wear
Tread depth alone cannot predict cuts, bulges, punctures, aging, pressure loss, alignment, rotation effects, uneven shoulders or heat damage. Wear rate can change with load, route, season and driver behavior. Follow manufacturer guidance, legal requirements, inspection standards, pressure controls and qualified vehicle assessment before keeping a tire in service or planning replacement.
Frequently asked questions
How is wear rate calculated?
Observed tread loss is divided by the entered distance used.
What if no tread loss is entered?
The result states that there is insufficient observed wear.
Does the forecast prove roadworthiness?
No. Condition inspection and applicable limits remain controlling.
