Explain the term “gross axle weight”:

1. The measured pressure at the tips of the chassis connected springs.
2. The own weight of each vehicle axle, including the wheels installed on it.
3. Correct answer: The overall weight of all the wheels installed on one axle against the road.
4. The own weight of the rear axle that includes the differential system.

WhyGross axle weight is how hard all the wheels of one axle press on the road. It is not the weight of the axle itself.
