Towing and Hitch Tips for Motorcycle Trailers Utility
Trailers Hitch Accessories
FOUR Critical WEIGHT Units in POUNDS you need to KNOW:
1. Towing Vehicle Capacity 2. Hitch Load Capacity
3. Trailer Load Limit 4. Hitch Tongue Weight Limit
The trailer weight fully loaded should not exceed the gross towing
weight capacity of the towing vehicle and the hitch. The maximum
vehicle towing capacity is the entire trailer weight including the load weight is the
GROSS weight.
- Compact cars can typically tow loads weighing up to 1,000 lbs. to 1,500 lbs. gross load.
- Large Rear Wheel Drive cars and minivans can be tow rated up to 3,500 lbs.
- Light Duty pickup trucks and SUVs can be tow rated up to 5,000 lbs
- Special Heavy Duty Pickups and SUVs with heavy duty tow packages can be tow rated up to 8,000 lbs.
- Dually pickups with Fifth wheel or Goose neck tow packages can be rated to tow 10,000 lbs. or even more.
Be sure what your vehicle/hitch set up is rated to tow. Please check with your vehicle/hitch dealer for this information.
Even if you have a class II hitch rated for up to 3,500 pounds, your front drive midsize car many
not be safe to pull more than 1,500 lbs. Many cars today have and automatic overdrive transmission
for better gas mileage that may be subject to damage if you tow a trailer and do not lock out the overdrive
feature. We always recommend consulting a factory authorized dealer about adding a hitch and lighting
to your vehicle and safe towing procedures for your make and model.
Hitches are rated for TWO Critical Weight Units, gross towing weight (GTW) and
tongue weight Limit (TW). With the many receiver hitch accessories available today you should be
sure you know not only what the LOAD LIMIT you can tow is BUT how much the weight limit is you can safely place
on the tongue of the hitch. The following chart shows classes and general weight ranges of those classes.
ALWAYS consult a dealer of your vehicle and or hitch brand to know what is correct for YOUR set up!

Many motorcycle, small utility, and boat trailers can be towed
with small vehicles and a class I or II hitch. Larger utility
and Big Bike motorcycle trailers requite a full size tow vehicle with a class
II or larger hitch. Motorcycle towing set ups such,
as the
Motorcycle Caddy and dirt bike carriers like our
Bike Lift require
a 2 inch receiver hitch with minimum 500 lbs. tongue weight limit AND a large, Heavy Duty
set up tow vehicle (no cars or mini-vans), NOTHING
LESS will do. Bumper mounted trailer balls (like some rentals) are NOT
recommended by Motorcycletrailer.com to tow anthing we sell. Always
consult a local factory dealer, or reputable shop that installs hitches
to determine your trailer hitch needs.
Trailer Loading and Tongue Weight
Trailer tongue weight (TW) is the amount of downward weight on the
tongue. The tongue weight should be 10 to 15% of the total trailer
weight. For example, a trailer with a gross weight of 1500 lbs.
should have the load evenly distributed so that the tongue weight
is 150 to 225 lbs.Too much tail weight may cause the trailer to
weave back and forth becoming the trailer wagging the dog.
Too much tongue weight can damage the hitch, as well as lower the rear and
raise the front of the tow car. This condition will cause your vehicle to
handle sloppy and brake much slower. Load the heaviest cargo on the trailer floor
in front of the axle. A front to rear balance of 60% to 65% should provide a good
tongue weight to pull smoothly. NEVER load a trailer for a negative or very neutral
tongue weight as this can actually act to shove the rear of the tow car up during heavy
breaking.
Hitch Height
Any trailer should sit close to level when atrtached to the tow car. Hitch height is
measured from the ground to the base of the trailer ball.
Typical hitch height to the ball should be around 15 to 18 inches.
If the trailer coupler is too low or too high, our
RHOST1 (Receiver Hitch Offset Tube)
can be used to adjust the hitch height up or down.
Every Time You Couple a Trailer
- Always inspect the hitch and tongue for cracks before towing
a trailer.
The trailer ball should be lightly greased.
- The safety chains should be long enough for tight turns and
be crossed for better handling in case of a hitch or coupler failure.
The safety chains should not drag on the ground for they can wear
to an unsafe condition in a very short time.
- The lighting hookup wire should have enough slack for tight
corners yet not drag on the ground. Petroleum based grease should
not be applied to plastic electrical connectors such as 4-pin
flat plugs. If a water seal or lubricant is required, use silicone
grease.
- Check lug nut tightness before each trip. The lug nuts should
be approximately 90 ft. lbs.or very tight with a small to medium
size lug wrench. Also recheck any wheel that has been removed
and replaced after towing 25 to 50 miles. Do not drive a loaded
trailer with a missing lug nut or damaged lug bolt. Wheel lug
nuts are usually tightened evenly in a star pattern for 5 lug
wheels or a cross pattern for 4 lug wheels, crossing over to opposite
sides as you work around the wheel.
Wheel Bearing Maintenance
Trailer wheel bearings or axle bearings should be greased every
six months and before long trips. It is a good idea to check them
occasionally on long trips, especially when hauling a heavy load.
Do this by carefully feeling the hub for excessive heat. Caution:
If the bearing is adjusted too tight or is running without grease
it can get VERY hot! A hot bearing needs immediate attention. Most
often either more grease or proper adjustment will ease the problem,
but replacement may be necessary.
Note: Boat trailers are a particular source of wheel bearing problems
as they are often put in and out of the water. A warm bearing that
is suddenly cooled by being immersed in water tends to suck water
into the inside as the air cools and shrinks. The water causes the
bearings to rust and fail. Spring-loaded pressurized
bearing protectors help to eliminate this problem.
Trailer Gross Vehicle Weight (GVW) Rating
Trailer springs, axles, tires and chassis are all rated for a total
maximum weight. The gross vehicle weight is the empty trailer plus
the deck, box sides, stake sides, and everything that is attached
to or inside of the trailer. For instance, if the GVW rating is
1,600 lbs. and the empty trailer weighs 400 lbs., a properly loaded
cargo of 1,200 lbs.may safely be towed in this trailer.
