pg. 50 Points to remember
Weight distribution affects handling
At the specified curb weight your car has a tendency to understeer, which means that the steering wheel
has lo be turned more than might seem appropriate for the curvature of a bend. This ensures good
stability and reduces the risk of rear wheel skid. Remember that these properties can alter with the
vehicle load. The heavier the load in the trunk, the less the tendency to understeer.
Loads should be distributed so that capacity weight or maximum permissible axle loads are not
exceeded.
Handling, roadholding
Vehicle load, tire design, and inflation pressure, all affect vehicle handling. Therefore, check that the
tires are inflated to the recommended pressure according to the vehicle load.
See "Tire pressure" section.
WARNING!
It is recommended that tires of the same make and dimensions be used on all four wheels. Do not use
bias ply tires as this will adversely alter vehicle handling characteristics.
