After you have loaded the trailer, weigh the trailer and

then the tongue separately, to see if the weights

are proper. If they are not, you may be able to get them

right by moving some items around in the trailer.

Trailering may be limited by the vehicle’s ability to carry

tongue weight. Tongue weight cannot cause the vehicle

to exceed the GVWR (Gross Vehicle Weight Rating) or

the RGAWR (Rear Gross Axle Weight Rating). The effect

of additional weight may reduce your trailering capacity

more than the total of the additional weight.

Consider the following example:

A vehicle model base weight is 5,500 lbs (2 495 kg);

2,800 lbs (1 270 kg) at the front axle and 2,700 lbs

(1 225 kg) at the rear axle. It has a GVWR of 7,200 lbs

(3 266 kg), a RGAWR of 4,000 lbs (1 814 kg) and a

GCWR (Gross Combination Weight Rating) of

14,000 lbs (6 350 kg). The trailer rating should be:

You can expect tongue weight to be at least 10 percent

of trailer weight (850 lbs (386 kg)) and because the

weight is applied well behind the rear axle, the effect on

the rear axle will be greater than just the weight

itself, as much as 1.5 times as much. The weight at the

rear axle could be 850 lbs (386 kg) X 1.5 = 1,275 lbs

(578 kg). Since the rear axle already weighs 2,700 lbs

(1 225 kg), adding 1,275 lbs (578 kg) brings the

total to 3,975 lbs (1 803 kg). This is very close to, but

within the limit for RGAWR as well. The vehicle is set to

trailer up to 8,500 lbs (3 856 kg).

But let’s say your speciﬁc vehicle is equipped with some

of the latest options and you have a front seat passenger

and two rear seat passengers with some luggage and

gear in the vehicle as well. You may add 300 lbs (136 kg)

to the front axle weight and 400 lbs (181 kg) to the rear

axle weight. Your vehicle now weighs:
