Load Rating Calculator
There are a number of things to consider when working out your vehicle’s load rating, and we want to help you understand the capacity of your racks and vehicle roof. Firstly, different vehicles have different ratings. You need to know the load rating of your vehicle. This information will be easy to find in your vehicle’s owners manual.
Secondly, there are a few different load ratings you need to understand. There are on-road and static ratings for all vehicles, as well as off-road ratings for vehicles that can travel off-road.
- On-road refers to the load rating of a vehicle when traveling on a sealed road.
- A static rating is the load rating of a stationary vehicle, and is necessary if you’re using a rooftop tent for example.
- The off-road load rating refers to a vehicle traveling on an unsealed road that does not contain a surface protection layer. Sometimes, manufacturers will list the load ratings in the vehicle’s Owners Manual, however, you can calculate the off-road load rating yourself using the formula provided in your product fitting instruction.
Lastly, it is important to remember the on-road rating does not take into consideration the weight of the roof racks. According to our instructions, the on-road rating + weight of the racks is called roof allowance. But remember, if you buy an accessory or holder and attach it to your rack or tray, you must also include the weight of these items in the load.
It is very unsafe to overload your vehicle. The “just wing it” approach is not appropriate in this context, and failure to follow the load ratings in each circumstance could result in damage to your vehicle, potential loss of your load, voiding warranty or insurance or cause traffic accidents. It’s illegal to overload your vehicle.
To get started calculating your vehicle's load rating, you'll need to make a note of your vehicle's load rating from your vehicle's owners manual as well as the Rhino-Rack Roof Rack system you have installed on your vehicle. Once you have this information you can begin by entering your vehicle details below.
