Meaning
Consumer information regarding comparison to specified base
tires (standardized test procedure) ⇒ꢀ ⇒ꢀpage 284:

referenced to a U.S.-specific standard test.
Traction rating under wet conditions (AA, A,

test bench speeds (A, B or C).
Additional numbers found on the tire could either be tire manu-
facturer internal labels or country-specific labels (such as for
Brazil and China).
Unidirectional tires
Unidirectional tires are designed to rotate only in one direction. Unidi-
rectional tires have arrows on the sidewalls that show the direction of
rotation. Make sure you mount the tire so that it rotates in the proper
direction. The tire's performance with regard to hydroplaning, traction,
noise, and wear is worse if it is not mounted in the proper direction of
rotation.
If you have to mount a tire opposite to its proper direction of rotation,
you must drive more carefully, since the tire is no longer being used
as designed. This is particularly important on wet roads. You must
replace or remount the tire as soon as possible in order to restore the
correct direction of rotation.
Load rating code
The load index indicates the maximum permissible load per individual
tire in pounds (kilograms).
