TIRE SELECTION UNDERSTANDING THE CORRECT FITMENT

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

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

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

INFLATION MAINTENANCE

INFLATION MAINTENANCE

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

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 WWW.SAFECAR.GOV EXPERTS SAY 25% OF TIRES ARE UNDERINFLATED

Info Only - Consult www.rma.org 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 www.rma.org

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 ! Info Only - Consult www.rma.org

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

TIRE REGULATIONS U.S. MARKET REQUIREMENTS

U.S. TIRE REGULATIONS www.nhtsa.gov 49 CFR Part 571 Std 139 - Pneumatic Tires for Light Vehicles 49 CFR Part 571 Std 110 - Tire Selection & Rims 49 CFR Part 575 Std 104 - UTQG 49 CFR Part 571 Std 119 - 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.

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

STD 110 - 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.

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.

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

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

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"

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
