1. A method for determining a tractor longitudinal force threshold value (I) for a tractor longitudinal retardation force (II) that can be imparted on a tractor (12) of a vehicle combination (10) comprising said tractor (12) and a trailer (14) for retarding said vehicle combination, said tractor (12) comprising a set of tractor wheels (18) adapted to engage the ground supporting said tractor (12), each wheel of said set of set of tractor wheels (18) comprising a tire, said method comprising: - determining a tractor lateral force value (III), indicative of a tractor lateral force being or predicted to be imparted on said tractor (12), - determining a tractor tire lateral force limit value (IV) using a tire model for determining a tire lateral force limit, taking at least one characteristic of the tire into account, for each wheel of at least a subset of said set of tractor wheels (18); - determining a reference lateral force value (V) using said tractor lateral force value (III) and said tractor tire lateral force limit value (IV); - determining a horizontal friction force value (VI) indicative of a possible total horizontal frictional force obtainable between said ground supporting said tractor (12) and said set of set of tractor wheels (18), and determining said tractor longitudinal force threshold value (I) using said reference lateral force value (V) and said horizontal friction force value (VI).
