SAFETY INFORMATION: THE FOLLOWING INFORMATION MUST BE GIVEN TO PURCHASING PERSONNEL, MOTORCYCLE TECHNICIANS, TIRE FITTERS AND CUSTOMERS.
TYPICAL TIRE MARKINGS
01 Nominal section width, expressed
in metric, inch or alpha; see size
chart below.
02 Ratio between tire section height and
nominal section width. This ratio is
not indicated when section width is
expressed in inches (eg. 3.50-18).
03 Code for tire construction
(- = Bias, R = Radial, B = Bias Belted).
04 Nominal rim diameter size in inches.
05 “Motorcycle” in abbreviated form.
Differentiates motorcycle tires

as applicable.
08 Expresses the tire’s maximum load
capacity (pounds) at the pressure
indicated (psi); see load index
chart below.
09 Indicates where the tire
was produced.
10 Abbreviation of “US Department
of Transportation.” Serves to
indicate that the tire conforms
to the regulations issued by The
US Department of Transportation.

MAINTAIN RECOMMENDED TIRE PRESSURE AND FOLLOW THE PUBLICATION(S) AND/OR WEBSITE(S) (COLLECTIVELY “PUBLICATIONS”) OF THE MOTORCYCLE MANUFACTURER
AND THE TIRE MANUFACTURER (COLLECTIVELY “MANUFACTURER”).
FAILURE TO FOLLOW MANUFACTURER’S RECOMMENDATIONS AND REQUIREMENTS CAN CAUSE TIRE FAILURE RESULTING IN SERIOUS INJURY OR DEATH.
ALL TIRES SHOULD BE MOUNTED ONLY BY TRAINED PERSONNEL. ONLY PROPERLY TRAINED PERSONNEL USING PROPER TOOLS AND SAFETY EQUIPMENT SHOULD
UNDERTAKE MOUNTING OF TIRES AND THEY SHOULD FOLLOW RECOMMENDED PROCEDURES, ESPECIALLY FOR ATV/ UTV TIRES, INCLUDING BUT NOT LIMITED TO THE
FOLLOWING: (I) USE ONLY A CLIP-ON STYLE AIR CHUCK WITH A LONG EXTENSION HOSE, REMOTE FILLER AND INFLATION GAUGE; (II) USING A TIRE MOUNTING LUBRICANT,
LUBE THE TIRE AND RIM BEAD SEAT; (III) THE TIRE AND WHEEL MUST BE LOCATED AWAY FROM ALL PERSONNEL USING A SOLID BARRIER LIKE A BLOCK WALL OR TIRE
MOUNTING CAGE BETWEEN THE TIRE/ WHEEL ASSEMBLY AND THE INSTALLER WITH THE TIRE/ WHEEL ASSEMBLY BEING OUT OF “LINE OF SIGHT” DURING THE INFLATION
PROCESS; (IV) DETERMINE THE TIRE’S MAXIMUM RECOMMENDED TIRE INFLATION PRESSURE; (V) REMOVE THE VALVE CORE FROM THE VALVE, INFLATE THE TIRE UNTIL THE
BEADS’ SEAT SNAP OR UNTIL THE MANUFACTURER’S MAXIMUM RECOMMENDED TIRE PRESSURE IS REACHED BUT NEVER EXCEED THE TIRE MANUFACTURER’S MAXIMUM
PRESSURE; (VI) IF THE TIRE BEADS DO NOT SNAP, STOP AND RELEASE ALL AIR FROM THE TIRE/ WHEEL ASSEMBLY AND CALL THE MANUFACTURER FOR HELP; (VII) ONCE THE
TIRE BEAD IS SEATED, DISCONNECT THE CHUCK, RE-INSTALL THE VALVE CORE AND INFLATE TO PROPER OPERATING PRESSURE.
