QUALITY GRADES
Tire Quality Grades apply to newpneumatic passenger car tires. TheQuality grades can be found whereapplicable on the tire sidewall betweentread shoulder and maximum sectionwidth. For example: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that the UnitedStates Department of Transportation hasset.
Tire Quality Grades apply to newpneumatic passenger car tires. They donot apply to deep tread, winter-typesnow tires, space-saver or temporaryuse spare tires, light truck or LT typetires, tires with nominal rim diameters of10 to 12 inches or limited production tires
as defined in Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department of Transportation Tirequality grades: The U.S. Department ofTransportation requires us to give youthe following information about tiregrades exactly as the government haswritten it.
Treadwear
The treadwear grade is a comparativerating based on the wear rate of the tirewhen tested under controlled conditionson a specified government test course.For example, a tire graded 150 wouldwear 1½ times as well on thegovernment course as a tire graded 100.The relative performance of tiresdepends upon the actual conditions oftheir use, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.
Traction AA A B C
WARNING: The traction gradeassigned to this tire is based onstraight-ahead braking traction tests,and does not include acceleration,cornering, hydroplaning or peaktraction characteristics.

What to do when a tire is punctured
A tire puncture within the tire's tread areacan be repaired in two stages with the kit.
•In the first stage, the tire is reinflated witha sealing compound and air. After the tirehas been inflated, drive the vehicle ashort distance approximately 4 mi (6 km)to distribute the sealant in the tire.
•In the second stage, check the tirepressure and adjust, if necessary, to thevehicle's specified tire inflation pressure.
First Stage: Reinflating the Tire withsealing compound and air
WARNING: Do not stand directly overthe kit while inflating the tire. If you noticeany unusual bulges or deformations in thetire's sidewall during inflation, stop and callroadside assistance.
WARNING: If the tire does not inflateto the recommended tire pressure within15 minutes, stop and call roadsideassistance.
Park the vehicle in a safe, level and securearea, away from moving traffic.
Turn the hazard lights on. Apply the parkingbrake and power off the vehicle. Inspect theflat tire for visible damage.
If a puncture is located in the tire sidewall,stop and call roadside assistance.
1.Remove the valve cap from the tire valve.
2.Unwrap the dual purpose hose (blacktube) from the back of the compressorhousing.
