What do you mean by max greadeability of vehicle?

Max gradeability of a vehicle refers to its ability to ascend a slope or incline without losing traction or power. It is typically expressed as a percentage or in degrees, indicating the maximum gradient the vehicle can climb while fully loaded. This measurement is crucial for evaluating the performance of vehicles in hilly or mountainous terrains, especially for trucks and off-road vehicles. A higher gradeability indicates better performance in challenging driving conditions.
