,tires with amaximum speedofover
149 mph (240km/h )mayhave "ZR"int he

Load-bearing index:load-bea ringindex 0083is
an umerical codethatspecifies themaximum
load-bea ringcapacity ofat ire.
Do not overload thetires byexceeding the
specified loadlimit. Themaximum permissible
load canbefound onthe vehicle's Tireand
Loading Information placardonthe B-pillar on
the driver's side(Ypage 280).
Example:
Load-bearing index91indicates amaximum
load of1,356 lb(61 5kg)that thetires can
bear. Forfurther information onthe maximum
tire load inkilograms andlbs,see
(Y page 286).
For further information onthe load bearing
index, see"Load index" (Ypage 286).
Speed rating: speedrating0084specifies the
approved maximum speedofthe tire.
