3. TIRE SELECTION
UNDERSTANDING THE CORRECT FITMENT

4. REFerence: Vehicle Placard
TIRE SELECTION
CONSIDERATIONS:
Size
Load Rating
Speed Rating
Inflation
REFerence: Vehicle Placard

5. TIRE SELECTION FITMENT CONSIDERATIONS: Recommend replacing 4 tires
Alternatively, new tires should be fitted to rear axle

8. INFLATION MAINTENANCE
#1 - PROPER INFLATION:
FOLLOW PLACARD OR CONSULT MFR

9. INFLATION MAINTENANCE

11. INFLATION MAINTENANCE
RECOMMEND MONTHLY CHECKS -
TPMS DOES NOT ALERT UNTIL -25%
VALVE CAP USAGE IMPORTANT

12. TIRE MAINTENANCE BENEFITS OF INFLATION MAINTENANCE: Tread Wear
Tire Longevity
Fuel Efficiency
Optimal Ride & Handling
Shorter Braking Distances
Reduce Carbon Dioxide Emissions
For more information refer to
EXPERTS SAY 25% OF TIRES ARE UNDERINFLATED

TIRE REPAIRS
#1 - INSPECTION & ASSESSMENT:
Remove the tire from the rim
Determine if the puncture is repairable
Location of the injury
Size of the injury
Inspect the inside of tire
'Run low on air'
Extent of the damage
Info Only - Consult

15. Info Only - Consult www.rma.org
TIRE REPAIRS
#2 – GENERAL PROCEDURES:
Clean the innerliner around the hole
Buff the innerliner around the hole
Drill out the hole to clean it up
Cement the area
Apply 'Combi' unit or 'Plug & Patch'
Check valve before re-installing !

18. TIRE ROTATION #1 – DO IT (REGULARLY) ! #2 – CROSS ROTATION IF POSSIBLE
#3 – COMBINE WITH INSPECTION
Inside / Outside Tire Wear
Tire Damage or Injury
Good Time to Check Inflation
Suspension Damage, Need for Align…

TIRE ROTATION
PATTERNS:
For more info see
All allow for reverse direction of rotation except for 'D'
Leading edge becomes the trailing edge of element

20. TIRE ROTATION BENEFITS: Extend Tire Life by Lessening Irregular Wear
Tires tell a story about condition of vehicle
Helps you to identify maintenance issues before they become big problems

VEHICLE ALIGNMENT

22. VEHICLE ALIGNMENT PROPER ALIGNMENT OF WHEEL ENDS –
Allows vehicle to track straight on road
Is beneficial to vehicle handling
Generally results in more even tire wear

24. TIRE REGULATIONS
U.S. MARKET REQUIREMENTS

25. U.S. TIRE REGULATIONS www.nhtsa.gov
49 CFR Part 571 Std Pneumatic Tires for Light Vehicles
49 CFR Part 571 Std Tire Selection & Rims
49 CFR Part 575 Std UTQG
49 CFR Part 571 Std Pneumatic Tires for Vehicles Other Than Passenger Cars
Part of a series of Motor Vehicle Safety Regulations issued beginning in 1967 focusing on Crash Avoidance and Crash Worthiness.
The original safety standard for light duty tires (Std 109) was replaced by Std 139 in 2007 as a result of the Tread Act.

26. STD 139 - TIRES Applies to vehicles with GVWR < 10,000 lbs
Requirements:
Size recognized by a tire standards organization
Specific sidewall markings
High speed test requirement
Endurance test requirement
Low pressure endurance test
Road hazard (plunger) test
Bead unseating test
Based on concept of 'Self Certification'
Symbol "DOT" Signifies Compliance to Std
All Tests are 'Indoor' Tests

27. STD TIRE SELECTION
Aimed more at vehicle manufacturers than tire manufacturers.
Intent is to prevent over-loading.
Defines vehicle weight limits.
Provides for 'placard' to communicate the vehicle's load limits, O.E. tire size & inflation, and O.E. rim size.

28. STD 104 - UTQG Provide Consumer Purchasing Information: Treadwear
Traction (on wet roads)
'Temperature Resistance'
Grades for Parts A. & B. based on outdoor testing at facilities in Texas against a CMT tire.
Grade for Part C. based on the indoor high speed test from MVSS-139.

29. UTQG - TREADWEAR
Treadwear grade based tire wear rate after 7,200 road miles as compared to the CMT tire wear rate.
No direct correlation to how many miles you will get.
Manufacturer cannot rate tires higher than measured grade.
"560"-A-B

30. UTQG - TRACTION
Traction grade based locked wheel 'skid number' on wet asphalt & wet concrete as compared to the CMT tire skid numbers.
Does not directly correlate with performance on vehicles with ABS.
Manufacturer cannot rate tires higher than measured grade.
560-"A"-B

31. UTQG - TEMPERATURE
Temperature (resistance) grade based indoor test wheel test at increasing speeds.
Does not directly correlate with long term tire performance.
Minimum time requirement for each grade, with "C" being the overall minimum.
560-A-"B"

32. U.S. TIRE REGULATIONS POTENTIAL CHANGES:
Discussion on-going concerning Fuel Efficiency grading in the U.S.
Plans are more well defined in Europe
Phase-in of letter grades beginning Nov, 2012
Unique grade system – A, B, C, E, F G (no D)
U.S. status unresolved
"Final" issued by NHTSA in March, 2010
Test procedure not defined
