IN TR O D U C T IO N 1. Industry Standard Firestone has developed a wide range of tire patterns and specifications, so that the proper Off-the-Road tire can be matched to any vehicle, service, or operating conditions. Load capacities, inflation pressures, dimensions such as overall tire diameter and width, as well as the relative rims and tube valves follow these standards. Firestone’s Off-the-Road tires are designed and produced to meet the commonly accepted international standards, those set by the TRA (Tire and Rim Association) in the U.S.A., by the ETRTO (European Tire and Rim Technical Organization) in Europe and/or by the JATMA (Japan Automobile Tire Manufacturers’ Association) in Japan*. If a tire is to be used for a purpose other than that for which it is originally intended, please consult Firestone Corporation for advice. *Where differences exist between the TRA, ETRTO and JATMA standards, Firestone selects the most applicable. 2.

2. Definitions 2.1 Tire 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 tire the aspect ratio is indicated by percentage. 2.5 Section Width (SW) “Section Width” is the width of a new tire, including 24- hour inflation growth and including normal sidewalls, but not including protective side ribs, bars, or decorations. Example Radial Tire ; 40.00R57, 33.25R35, 445/95R25 Bias Tire ; 21.00-35, 45/65-45 2.6 Static Loaded Radius and Width (SLR, SLW) “Static Loaded Radius” is the shortest distance from the axle center to the contact surface of a tire and “Static Loaded Width” is the overall width of a tire, mounted on the approved rim at the specified inflation pressure and placed still and vertically on a flat board, and loaded with the specified load. 2.2 Star Rating, Ply Rating and Load Index The load capacity of a tire is indicated by the star rating (in case of radial tire) and the ply rating (in case of bias tire). The load index is applied in countries where the ETRTO standards are used. 2.3 Overall Diameter (OD) “Overall Diameter” is twice the section height of a new tire, plus the nominal rim diameter, including 24-hour inflation growth. 2.7 Original Tread Depth (OTD) “Original Tread Depth” is the tread depth of a new tire measured at the point of tread-indicator where available or one-fourth the width of the tire crown section from the crown center, including 24-hour inflation growth. 2.4 Overall Width (OW) “Overall Width” is the width of a new tire, including 24- hour inflation growth, and including protective side ribs, bars or decorations.
