TELL US THE ROUTE. WE PICK THE A‑SERIES.
Cost per kilometre is decided by route profile, axle load and how often the truck runs loaded. Send those three and we answer with a model, a size and a price.
- Route profile and annual kilometres — the two numbers that decide tread depth
- Axle load in tonnes, loaded — not the truck's rated figure
- Size and rim you run today, plus monthly volume
