GVWR Explained: What Every Trailer Buyer Needs to Know
What Does GVWR Mean?
Understanding Trailer Weight Ratings Before You Buy
If you've ever shopped for an enclosed cargo trailer, you've probably seen the term GVWR. While it may seem like just another specification, GVWR is one of the most important numbers to understand before purchasing a trailer.
Knowing your trailer's GVWR helps you determine how much weight it can safely carry, whether your tow vehicle is capable of pulling it, and how to avoid overloading your trailer.
At Southern Trailer Depot, we've helped customers choose the right enclosed cargo trailer since 2007. Understanding GVWR is one of the first steps in selecting a trailer that will safely meet your needs for years to come.
What Does GVWR Mean?
GVWR stands for Gross Vehicle Weight Rating.
This is the maximum safe operating weight of the trailer when it is fully loaded.
GVWR includes:
- The weight of the trailer
- All cargo
- Tools
- Fuel
- Equipment
- Accessories
- Any permanently installed options
It is not just the amount of cargo the trailer can carry.
Simple Example
Imagine purchasing a trailer that has:
- Trailer Empty Weight: 1,200 lbs
- GVWR: 2,990 lbs
- Payload Capacity: 1,790 lbs
That means:
- Trailer = 1,200 lbs
- Cargo = 1790 lbs
- Maximum Weight = 2,990 lbs
You should never exceed the GVWR.
Why GVWR Matters
Choosing the proper GVWR affects:
- Safety
- Braking performance
- Tire life
- Suspension life
- Towing stability
- Insurance compliance
- Vehicle wear
- Trailer longevity
Overloading a trailer increases stopping distance and places unnecessary stress on the frame, axles, tires, bearings, brakes, and your tow vehicle.
Understanding the Different Weight Ratings
Empty Weight
Also called Dry Weight.
The trailer weighs this amount before cargo is added.
Payload Capacity
The amount of cargo you can safely load.
Formula:
GVWR − Empty Weight = Payload
GAWR
Gross Axle Weight Rating.
The maximum weight each axle can safely support.
Example:
Two 3,500 lb axles = 7,000 lb axle capacity
Tongue Weight
The amount of trailer weight pressing downward on the hitch.
Generally:
10–15% of total trailer weight.
Common GVWR Ratings
| Trailer | Typical GVWR |
|---|---|
| 6x12 Single Axle | 2,990 lbs |
| 6x12 Tandem | 7,000 lbs |
| 7x14 Tandem | 7,000 lbs |
| 7x16 Tandem | 7,000 lbs |
| 8.5x20 | 9,990 lbs |
| 8.5x24 | 9,990 lbs |
| 8.5x28 | 9,990–14,000 lbs |
| 8.5x36 Triple Axle | Up to 15,600 lbs |
How Much GVWR Do You Need?
Motorcycle
Usually 2,990–3,500 GVWR
Lawn Care
7,000 GVWR
Contractor
7,000–9,990 GVWR
Race Trailer
9,990 GVWR+

Common Buyer Mistakes
❌ Looking only at trailer size
❌ Ignoring payload capacity
❌ Buying too little GVWR
❌ Forgetting future equipment
❌ Exceeding tow vehicle capacity
Pro Tip
Most customers regret buying too little payload capacity—not too much.
If you're deciding between two trailers, it's often worth stepping up to the higher GVWR model if your tow vehicle can safely handle it.
Frequently Asked Questions
Does GVWR include the trailer?
Yes.
Can I increase my trailer's GVWR?
Generally, no. The GVWR is assigned by the manufacturer and depends on the frame, axles, suspension, brakes, wheels, tires, and other components.
What happens if I exceed GVWR?
You increase the risk of tire failure, brake issues, poor handling, excessive wear, and unsafe towing.
Is GVWR the same as payload?
No. Payload is only the weight you can add to the trailer. GVWR is the maximum weight of the trailer plus everything in it.
Where do I find the GVWR?
Look for the manufacturer's VIN/data plate, usually located near the tongue or on the driver's side front section of the trailer.
