4 Wheeler Trailer Weight Capacity and Sizing | Load Right

One or two 4-wheelers need a trailer rated at 1,200–2,500 lbs on a 5×8 deck; larger ATVs or multiple units need a 6×12 tandem-axle at 3,000–3,500 lbs.

Loading a 4-wheeler onto an undersized trailer turns a routine haul into a fishtailing hazard that can earn you a ticket before you reach the highway. Getting the 4 wheeler trailer weight capacity and sizing right on the first try means matching your machine—or machines—to a trailer that carries them safely, legally, and without white-knuckle moments. A single standard ATV fits comfortably on a 5×8 single-axle trailer rated at 1,200–2,500 lbs, while two ATVs or a side-by-side typically require a 6×12 tandem-axle unit rated at 3,000–3,500 lbs. The table below shows which trailer type fits your specific setup.

What Size Trailer Do You Need for Your 4-Wheeler?

The trailer size you need depends entirely on the number of ATVs you plan to haul and their combined weight. A single-axle utility trailer with a 5×8-foot deck and a load capacity of 1,200–2,500 lbs handles one standard ATV or two lighter youth models. If you own a larger utility ATV, a side-by-side, or plan to carry multiple machines, step up to a 6×12-foot tandem-axle trailer rated at 3,000–3,500 lbs.

Your ATV’s exact weight is listed in the owner’s manual or available from the dealer. Always confirm that number before buying a trailer—guessing leads to overloading.

Trailer Weight Ratings: What Each Number Means

Three ratings define what a trailer can safely carry, and confusing them is the most common mistake owners make. GVWR (Gross Vehicle Weight Rating) is the maximum total weight of the trailer plus its cargo—never exceed this number. GAWR (Gross Axle Weight Rating) is the max weight each individual axle can support; it’s listed on the trailer’s spec sticker. Payload capacity is what you actually have left for your ATV after subtracting the trailer’s own empty weight. The formula is simple: Payload = GVWR − Trailer Curb Weight. A trailer with a GVWR of 2,810 lbs and an empty weight of 480 lbs has a payload of 2,330 lbs—enough for one heavy utility ATV but not two.

CURT’s trailer weight guide explains these ratings in detail and is useful reference material when comparing models.

Trailer Types and Their Real Capacities

Not all trailers are built for the same job. Open utility trailers are the most common choice for ATV hauling, but enclosed trailers add weather and theft protection at the cost of payload. The table below breaks down the real-world capacity of each type.

Once you’ve identified the right capacity range, the next step is choosing a specific model that fits your machine dimensions. We’ve tested current models and compiled our recommended 4-wheeler trailer picks to help you compare deck sizes, build quality, and price points side by side.

How to Safely Load Your 4-Wheeler on a Trailer

Loading an ATV incorrectly shifts weight, stresses the trailer, and can cause an accident at highway speed. Follow this sequence every time.

Step 1: Inspect and prep. Check the ATV for loose parts, confirm tire pressure is correct, and test the brakes. Tighten the gas and oil caps to prevent leaks during transit. Inspect ratchet straps for fraying or worn webbing.

Step 2: Set up on level ground. Park the trailer on flat, stable ground and confirm the hitch is fully locked. Place ramps rated for your ATV’s weight at a shallow angle and verify they are secure against the trailer deck.

Step 3: Drive up slowly. Engage 4WD if available and drive the ATV up the ramp at a steady, slow pace. Do not attempt if the ramp is wet or slippery.

Step 4: Position using the 60-40 rule. Center the ATV left to right on the deck. Place 60% of the weight in front of the axle and 40% behind. On a single-axle trailer, position the ATV slightly forward of the axle. For multiple machines, load the heaviest one first and place it with its weight over the axle.

Step 5: Secure with four-point tie-downs. Use one heavy-duty ratchet strap per corner, rated for your ATV’s weight. Attach straps to the frame or lower suspension—never to handlebars or bumpers, which can bend or break. Crisscross the straps so they pull down and inward. Tighten until the suspension compresses slightly, then check that the ATV doesn’t shift when pushed.

The ATV sits solid with no visible movement when you rock it side to side. All four straps are taut, the ramps are stowed, and the trailer’s safety chains form an X under the hitch.

What Happens If You Overload Your Trailer?

At highway speeds, an overloaded trailer can sway uncontrollably or cause the tow vehicle to fishtail. Legally, operating over the GVWR can result in tickets and fines from DOT enforcement. The trailer’s axle rating matters too—exceeding the GAWR risks bending an axle or blowing a tire, even if the total GVWR is within limits.

Tongue weight is another critical limit. The weight the trailer tongue presses down on the hitch ball must stay within your tow vehicle’s payload capacity. Check your vehicle owner’s manual for the maximum tongue weight rating and use a tongue scale if you’re unsure.

Gross Combined Weight Rating (GCWR) is the final number to verify: the combined weight of the truck, trailer, ATV, passengers, and all cargo must not exceed the vehicle manufacturer’s limit. Exceeding GCWR strains the transmission and brakes on long grades.

Matching Trailer Capacity to Your ATV Class

Different ATVs weigh very different amounts, and the trailer that works for a 350-lb youth quad is dangerously undersized for a 1,800-lb side-by-side. Use this table to match your machine’s class to the minimum trailer capacity and recommended deck size.

If your ATV falls near the upper end of a capacity bracket, choose the trailer one class higher. Keeping the ATV weight at 80% or less of the trailer’s rated capacity leaves a safety margin for gear, accessories, and uneven weight distribution.

Hitching and Electrical Checks Before the First Trip

After loading, confirm the trailer sits level when connected. Measure the hitch height and adjust the draw bar if needed. Drop the trailer onto the ball, set the safety chains in an X formation under the hitch—this catches the tongue if the ball fails—and lock the latch with the safety pin. On newer trucks, test turn signals and brake lights after plugging in the wiring harness. Trailer brakes work differently than vehicle brakes, so allow extra following distance and take corners slower than you would without a trailer.
