Ram 1500/2500/3500: Tire Pressure

Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure:

  • Safety
  • Economy
  • Ride Comfort And Vehicle Stability

Safety

WARNING!

  • Improperly inflated tires are dangerous and can cause collisions.
  • Under-inflation increases tire flexing and can result in over-heating and tire failure.
  • Over-inflation reduces a tire's ability to cushion shock. Objects on the road and chuckholes can cause damage that result in tire failure.
  • Over-inflated or under-inflated tires can affect vehicle handling and can fail suddenly, resulting in loss of vehicle control.
  • Unequal tire pressures can cause steering problems.

    You could lose control of your vehicle.

  • Unequal tire pressures from one side of the vehicle to the other can cause the vehicle to drift to the right or left.
  • Always drive with each tire inflated to the recommended cold tire inflation pressure.

Economy

Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Under-inflation also increases tire rolling resistance resulting in higher fuel consumption.

Ride Comfort And Vehicle Stability

Proper tire inflation contributes to a comfortable ride.

Over-inflation produces a jarring and uncomfortable ride. Both underinflation and over-inflation affect the stability of the vehicle and can produce a feeling of sluggish response or over responsiveness in the steering.

NOTE:

  • Unequal tire pressures from side to side may cause erratic and unpredictable steering response.
  • Unequal tire pressure from side to side may cause the vehicle to drift left or right.
