If a vehicle is parked/not operated for a long period of time, tires may develop “flat spots”. Once the vehicle is driven again, these flat spots may cause a vibration which typically disappears gradually as the tires warm up and regain their original shape. To minimize tire flat spots developing during periods of extended storage, inflate the tires to the maximum pressure as indicated on the tire’s sidewall. When the vehicle is made ready to drive again, lower the tire pressure to the recommended levels as shown on the Tire and Loading Information label in the driver’s side center pillar for your vehicle (Refer to More Details).
