How fleet tyre forecasting works
Forecasting tells you which tyres need budgeting first. From the tread worn so far and the distance covered, you get a wear rate; from the tread remaining above the legal minimum, you get the distance left; and from the fleet's monthly kilometres, you get a run-out date:
wear rate = tread used ÷ distance used · remaining km = (current tread − minimum) ÷ wear rate · run-out odometer = current odometer + remaining km
This free tool forecasts the tyres you enter. TreadOS does it automatically for the whole fleet from real inspection history — wear rate, remaining tread and projected replacement date for every wheel, with alerts before tyres reach the minimum.
