kg ) is installed in the vehicle for the child to use , the calculations are as follows :
1 . Calculate the total weight .
2 . Calculate the available load capacity .
3 . The total weight now exceeds the capacity weight by 22 lbs ( 10
|
kg ), so the cargo weight must be reduced by 22 lbs ( 10 kg ) or more .
& Determining Compatibility of Tire and Vehicle Load Capacities s13ab06
The sum of four tires ’ maximum load ratings must exceed the maximum loaded vehicle weight (“ GVWR ”). In addition , sum of the maximum load ratings of two front tires and of two rear tires must exceed each axle ’ s maximum loaded capacity (“ GAWR ”). Original equipment tires are designed to fulfill those conditions .
The maximum loaded vehicle weight is referred to Gross Vehicle Weight Rating ( GVWR ). And each axle ’ s maximum loaded capacity is referred to Gross Axle Weight Rating ( GAWR ). The GVWR and each axle ’ s GAWR are shown on the vehicle certification label affixed to the driver ’ s door .
The GVWR and front and rear GAWRs are determined by not only
|
the maximum load rating of tires but also loaded capacities of the vehicle ’ s suspension , axles and other parts of the body .
Therefore , this means that the vehicle cannot necessarily be loaded up to the tire ’ s maximum load rating on the tire sidewall .
& Adverse Safety Consequences of Overloading on Handling and Stopping and on Tires s13ab07
Overloading could affect vehicle handling , stopping distance , vehicle and tire as shown in the following . This could lead to an accident and possibly result in severe personal injury .
. Vehicle stability will deteriorate .
. Heavy and / or high-mounted loads could increase the risk of rollover .
. Stopping distance will increase .
. Brakes could overheat and fail .
. Suspension , bearings , axles and other parts of the body could break
