2 The following measurements strictly follow these standards: Load capacities, inflation pressures, dimensions (such as overall tire diameter and width), as well as the relative rim and tube a tire is to be used for a purpose other than that for which it is originally intended, please consult COLORADO OTR, LP for reference on application and Vehicle Matching ChartAPPLICATIONVEHICLEE arthmover ServiceDump Trucks, Motor Scrapers, Articulated Dump Trucks, Coal Haulers, Logging Trucks, Other Mining Trucks, & Dozer ServiceShovels, Front-End Loaders, Back-hoe Loaders, Skid Steer Loaders, Dozers, Shuttle Trucks, Load-Haul-Dumps, OTR LP4 GENERAL INFORMATIONS tructural Diagrams - Radial TireStructural Diagrams - Bias-Ply TireGeneral InformationTREADTREADTREAD BELTSTREAD BELTSBODY PLYSBODY PLYSTURN-UP PLYSIDEWALLBEAD BUNDLEBEAD BUNDLEBEAD CHAFER (FILLER)

3 INNER LINERINNER Size - The size of each tire is indicated by nominal width and rim diameter in inches and mm. Radial structure is indicated by the letter R . For some tires the aspect ratio is indicated by , , 445/95R25 Bias , 45/65-45 Star Rating, Ply Rating and Load Index - The load capacity of a tire is indicated by the star rating (in case of a radial tire) and the ply rating (in case of a bias tire).*The load index is applied in countries where the ETRTO standards are Diameter (OD) - Overall Diameter is twice the section height of a new tire, plus the normal rim diameter, and including 24-hour inflation Width (OW) - Overall Width is the width of a new tire, including 24-hour inflation growth, and including protective side ribs bars or Width (SW) - Section Width is the width of a new tire, including 24-hour inflation growth and normal sidewalls; BUT, not including protective side ribs, bars, or Loaded Radius and Width (SLR, SLW) - Static Loaded Radius is the shortest distance from the axle center to the contact surface of a tire.

4 Static Loaded Width is the overall width of a tire mounted on the approved rim at the specified inflati on pressure, placed still and vertically on a flat board, and loaded with the specified Tread Depth (OTD) - Original Tread Depth is the tread depth of a new tire measured at the point of the tread-indicator (where available); OR, one-fourth the width of the tire crown section from the crown center, and including 24-hour inflation Height (SH) - Section Height is the distance from the heel of the bead to the crown section of the tire, and includes the original tread Ratio Aspect Ratio is represented as a percentage to determine the Section Height. Speed Rating - Speed Rating is represented by an alpha symbol on the sidewall and is defined as the maximum continuous speed allowed for a pre-determined period of one Kilometer per Hour (TKPH) - Ton Kilometer per hour is a formulated representation of the amount of work that is applied to a tire over a specified period of one OTR TKPH Formula - To calculate TKPH the following formula applies:TKPH Work RateAverage Tire Load X Average Speed per ShiftAverage Tire LoadEmpty Tire Load in Tons + Loaded Tire Load in Tons2 Average SpeedCycle Distance in Km X Number of Cycles per ShiftHours per TKPH formula will ensure optimum performance from OTR Tires.

5 This formula MUST be adhered to. Failure to do so will result in premature failure of the tire due to excessive heat buildup. To avoid excessive heat buildup, a tire with a TKPH rating that is higher than that of the work rate calculated must be selected. Each tire position on the machine must be calculated and considered individually. A position with the highest average tire load should be imperial measurements; Ton Mile per Hour (TMPH): the formula remains the same, noting (TMPH) figures must be selected from the (TKPH)-(TMPH) data fields. *Any tire or tires found to be working outside of their recommended TKPH-TMPH will NOT be subject to manufacturer s warranty.
