Need to know the specific model and configuration (e.g., single axle, tandem, tri-axle, quad axle, centipede) in order to answer this.
Volvo makes a wide range of trucks in varying weight classes. You would need to list a specific model and configuration.
Well, the question is really too vague to be answered. You said gross weight, implying you want a loaded weight. Volvo manufactures and sells many different models of trucks worldwide. We have no way of knowing if you're referring to a Volvo truck in the United States, South Africa, Australia, the United Kingdom, etc. The allowable gross weights will vary between jurisdictions. Also, you did not say what configuration of truck - again, for all we know, you could be referring to a single axle straight/rigid truck, a tandem axle, a tandem axle with additional lift axles, tandem axle twin steer, single axle articulated truck, tandem axle articulated truck, etc. Typically, however, a sleeper cab truck and daycab truck are allowed the same gross weights.
You need to include a model. It's not going to be the same for a Volvo car as it is for a Volvo semi truck.
No way to answer without knowing the model, axle weight ratings, and wheelbase.
