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

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 !

TIRE ROTATION

PATTERNS:

All allow for reverse direction of rotation except for 'D'Leading edge becomes the trailing edge of element

TIRE ROTATION

BENEFITS:Extend Tire Life by Lessening Irregular Wear

Tires tell a story about condition of vehicleHelps you to identify maintenance issues before they become big problems

TIRE REGULATIONSU.S. MARKET REQUIREMENTS

U.S. TIRE REGULATIONS

49 CFR Part 571 Std 139 - Pneumatic Tires for Light Vehicles49 CFR Part 571 Std 110 - Tire Selection & Rims49 CFR Part 575 Std 104 - UTQG49 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.

www.nhtsa.gov

STD 139 - TIRES Applies to vehicles with GVWR < 10,000 lbs Requirements:

Size recognized by a tire standards organizationSpecific sidewall markingsHigh speed test requirementEndurance test requirementLow pressure endurance testRoad hazard (plunger) testBead 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 - UTQGProvide Consumer Purchasing Information:

A. TreadwearB. Traction (on wet roads)C. '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 - TREADWEARTreadwear 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 - TRACTIONTraction 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 REGULATIONSPOTENTIAL CHANGES:

Discussion on-going concerning Fuel Efficiency grading in the U.S.

Plans are more well defined in EuropePhase-in of letter grades beginning Nov, 2012Unique grade system – A, B, C, E, F G (no D)

U.S. status unresolved"Final" issued by NHTSA in March, 2010Test procedure not defined
