The weight rating.
Max allowed weight - tare (empty) weight = permissible payload weight.
The only information provided is that it's a 24' straight truck - that really tells us nothing in relation to the question you're asking. The payload it can haul is the tare weight (empty weight of the vehicle) subtracted from the Gross Vehicle Weight Rating. So, if it's a non-CDL Class 6 vehicle with a Gross Vehicle Weight Rating of 26,000 lbs. and a tare weight of 15,000 lbs., then it can haul 11,000 lbs. of payload. If it's a Class 7 truck (which does require a CDL) with a Gross Vehicle Weight Rating of 33,000 lbs., and a tare weight of 17,000 lbs., then it can haul 16,000 lbs. of payload. But without having the tare weight and Gross Vehicle Weight Rating of the vehicle you had in mind, it's impossible to tell you what you're looking for. Length doesn't determine how much weight it can haul.
Gross Vehicle Weight Rating, or GVWR is the rating given to a vehicle by the manufacturer. It can usually be found on the door pillar post (open the door and look for the sticker). Gross Combination Weight Rating is normally the weight assigned to a power unit (Truck Tractor) when speaking in terms of the weight of itself and the trailer. GCWR most generally would be 80,000 lbs., for a standard over the road truck configuration.
Takeoff weight is the total weight of an aircraft at the moment it lifts off the ground, which includes fuel, payload, and the aircraft itself. Landing weight is the weight of the aircraft at the moment it touches down on the runway, which is typically lower than the takeoff weight due to fuel burn during the flight. These weights are calculated based on the initial weight of the aircraft, fuel consumption, and payload changes during the flight.
The API rating is what is different. it is based on different additives that are put in the oil. and the oil weight will differ.
Yes and no, the weight of your payload + trailer weight on the truck cannot exceed the payload weight limit.
Load rating of the tire. The higher the number the higher the GVW Gross Vehicle Weight the tire is designed to handle.
The 'laden weight' is the weight of a vehicle carrying some or a full payload.
Open the driver side door and look for the gvwr on the white sticker. That number is the maximum weight you can haul. The maximum weight the rear axle can handle is the gross axle weight rating (gawr) which is also located on this sticker.
Payload dertimines the amount of weight your vehicle can carry safely while driving (Braking and Steering) Tow capacity means how much your vehicle can tow behind itself safely while driving. (braking and steering) Check your owners manual or cdall the dealer if not sure. Hope this helps
Legally, in the US, it's typically between 43,000 and 48,000 lbs of payload. The max legal interstate weight is 80,000 lbs. for the truck, trailer, and payload. How much the actual payload comes out to depends on the empty weight of the vehicle and trailer, and that'll be affected by a number of factors, such as the frame length of the truck, what the trailer is made of (steel or aluminum), etc.
