then calculate the axle loads and the actual gross vehicle weight. Add the wheel loads for
each axle and compare the total to the GAWR for that axle. If the total is greater than the
GAWR, then you exceed this rating. If the total is at or near the GAWR, a tire overload is
probably.
Now, add all of the wheel loads together and compare that total to the GVWR for your
coach. If the total exceeds the GVWR, then you exceed that rating.
Tire ratings
Be sure to compare your wheel loads to the ratings of your tires. Remember that tire ratings
vary with inflation pressure. If you discover a tire overload, resolve it immediately.
Knowledge of tire load and inflation ratings can improve tire performance -- and prevent
accidents.
Towed vehicle weight
If you tow a vehicle behind your motorhome, determine its weight and compare it to the
tow rating of your hitch system. Also, compare the total weight of your motorhome and
towed vehicle to the GCWR for your coach.
If you tow a trailer or another vehicle that imparts vertical load to your coach, you will want
to verify that this hitch load does not exceed the vertical load rating of your hitch.
Also, keep in mind that many chassis manufacturers specify that if a vehicle exceeding a
certain weight is to be towed, supplemental braking for the towed vehicle is required; so,
check with the chassis manufacturer.
