Operation Tires and wheels Tire load rating The tire load rating 5 ( page 322) is a numerical code associated with the maximum load a tire can support. For example, a load rating of 91 corresponds to a maximum load of 1356 lbs (615 kg) the tire is designed to support. See also "Maximum tire load" ( page 328) where the maximum load associated with the load index is indicated in kilograms and lbs. Warning! Warning! Tire speed rating The tire speed rating 6 ( page 322) indicates the approved maximum speed for the tire. Warning! G Do not overload the tires by exceeding the specified load limit or vehicle capacity weight as indicated on the placard located on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure. G Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the tires. Exceeding the maximum speed for which tires are rated can lead to sudden tire failure, causing loss of vehicle control and possibly resulting in an accident and/or personal injury and possible death, for you and for others.
