Gross Vehicle Weight Rating (GVWR)

If you plan on hauling a heavy load, it's wise to know your vehicle's GVWR. But what does GVWR mean, and how is it calculated? Let's look at some common acronyms that are used to determine the weight and towing capacity of your vehicle so you can make sure you never exceed its limits. At Arizona Trailers, we carry a large selection of new and pre-owned trailers to meet your hauling needs.

What Does GVWR Mean?

GVWR is an acronym that stands for the "gross vehicle weight rating" or "maximum loaded weight of your vehicle (or trailer)." Put simply, GVWR means it's the heaviest your vehicle or trailer can be as it moves from point A to point B, according to the manufacturer. This maximum weight includes the weight of your vehicle or trailer, the weight of each occupant, and the weight of everything else you've packed inside. The manufacturer considers the vehicle's suspension system, frame, wheels, and axles when calculating its GVWR.

How to Find Your Vehicle's GVWR

Every vehicle has a unique GVWR. You can find yours by checking the Safety Compliance Certification Label that's located inside the driver's side door jamb. This small sticker is packed with important information, including the VIN. Most often, the GVWR is displayed on the top right section, just under the manufacturer's name. If you need help finding your GVWR information, look online. All you'll need is your VIN. You can also ask our experts at Arizona Trailers. We'll help you locate your Safety Compliance Certification Label so you can determine your vehicle's GVWR.

What is GCWR?

GCWR stands for the "gross combined weight rating" of your vehicle and trailer. This number refers to the maximum amount of weight for your vehicle when it's attached to a trailer. This includes the weight of your vehicle, the weight of your trailer, all occupants, and the load you're hauling in the vehicle and on the trailer. 

The manufacturer has determined the maximum weight your vehicle and trailer can handle based on the frame strength, suspension system, and axles.

How to Find Your Vehicle's GCWR

Your vehicle's GCWR combines the weight of your vehicle and trailer (and everything inside). You can find your vehicle's specific GCWR rating by checking your vehicle's owner's manual. If you can't find it, check the manufacturer's towing guide. 

To determine whether you're under your GCWR, you'll need to know the weight of your cargo, the weight of your occupants, and the total curb weight of your vehicle and trailer. Make sure this number is lower than your GCWR before trying to pull a trailer on the road. Otherwise, you risk damage to your truck and trailer.

GVWR vs GCWR

Although the acronyms look similar, they stand for two very different numbers. Your GVWR meaning is the maximum amount that your vehicle or trailer should weigh when moving on the road. Your GCWR, on the other hand, is the maximum amount that your vehicle and trailer should weigh. Always double-check to make sure that you're under the GVWR and GCWR ratings before heading out.

Why GCWR is Important When Using a Trailer

Your GCWR rating takes into consideration the amount of weight that your vehicle and trailer can handle. The axles, suspension, and wheels can only carry so much weight before becoming damaged or causing hazardous conditions. If you attempt to pull a load that's over the GCWR, you're asking your truck and trailer to do more work than they're designed to handle, which can lead to expensive repairs.
