added to the front axle weight and

181 kg (400 lbs) to the rear axle

weight. The vehicle now weighs:

Weight is still below 3 266 kg

(7,200 lbs) and you might think

318 additional kilograms (700 lbs)

should be subtracted from the

trailering capacity to stay within

GCWR limits. The maximum trailer

would only be 3 538 kg (7,800 lbs).

You may go further and think the

tongue weight should be limited to

less than 454 kg (1,000 lbs) to

avoid exceeding GVWR. But the

effect on the rear axle must still be

considered. Because the rear axle

now weighs 1 406 kg (3,100 lbs),

408 kg (900 lbs) can be put on

the rear axle without exceeding

RGAWR. The effect of tongue

weight is about 1.5 times the actual

weight. Dividing the 408 kg (900 lbs)

by 1.5 leaves only 272 kg (600 lbs)

of tongue weight that can be

handled. Since tongue weight is

usually at least 10 percent of total

loaded trailer weight, expect that the

largest trailer the vehicle can

properly handle is 2 722 kg

(6,000 lbs).

It is important that the vehicle

does not exceed any of its

ratings — GCWR, GVWR, RGAWR,

Maximum Trailer Rating or Tongue

Weight. The only way to be sure it is

not exceeding any of these ratings

is to weigh the vehicle and trailer.

Total Weight on the Vehicle's

Tires

Inflate the vehicle's tires to the

upper limit for cold tires. These

numbers can be found on the

Certification label or see Vehicle

Load Limits

on page 9‑12

for more

information. Do not go over the

GVW limit for the vehicle, or the

GAWR, including the weight of the

trailer tongue. If using a weight

distributing hitch, do not go over the

rear axle limit before applying the

weight distribution spring bars.
