Nominal aspectratio: aspect ratio;isthe
size ratio between thetire height andthetire
width andisshown inpercent .The aspect ratio
iscalculated bydividing thetire width by
the tire height.
Tire code: tirecode =specifies thetire type.
"R" represents radialtires."D"represents

Load bearing index:loadbearing indexA
is anumerical codewhich specifies the
maximum load-bearing capacityofatire. G
WARNING The
tireload rating mustalwaysbe atleast
half ofthe GAWR ofyour vehicle. Otherwise,
sudden tirefailure maybethe result which
could cause anaccident and/orserious injury
to you orothers.
