  • Page 44: Tire Safety Information

    Tire Safety Information 1. T AFETY NFORMATION This portion of the User’s Manual contains tire safety information as required by 49 CFR 575.6. Section 2.1 contains “Steps for Determining Correct Load Limit - Trailer”. Section 2.2 contains “Steps for Determining Correct Load Limit – Tow Vehicle”. Section 2.3 contains a Glossary of Tire Terminology, including “cold inflation pressure”, “maximum inflation pressure”, “recommended inflation pressure”, and other non-technical terms.
  • Page 45 Excessive loads and/or underinflation cause tire overloading and, as a result, abnormal tire flexing occurs. This situation can generate an excessive amount of heat within the tire. Excessive heat may lead to tire failure. It is the air pressure that enables a tire to support the load, so proper inflation is critical.
  • Page 46 Bead The part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim. Bead separation This is the breakdown of the bond between components in the bead. Bias ply tire A pneumatic tire in which the ply cords that extend to the beads are laid at alternate angles substantially less than 90 degrees to the centerline of the tread.
  • Page 47 Intended outboard sidewall The sidewall that contains a white-wall, bears white lettering or bears manufacturer, brand, and/or model name molding that is higher or deeper than the same molding on the other sidewall of the tire or the outward facing sidewall of an asymmetrical tire that has a particular side that must always face outward when mounted on a vehicle.
  • Page 48 The linear distance between the exteriors of the sidewalls of an inflated tire, including elevations due to labeling, decorations, or protective bands or ribs. A layer of rubber-coated parallel cords. Ply separation A parting of rubber compound between adjacent plies. Pneumatic tire A mechanical device made of rubber, chemicals, fabric and steel or other materials, that, when mounted on an automotive wheel, provides the traction and contains the gas or fluid that sustains the load.
  • Page 49 That portion of a tire that comes into contact with the road. Tread rib A tread section running circumferentially around a tire. Tread separation Pulling away of the tread from the tire carcass. Treadwear indicators (TWI) The projections within the principal grooves designed to give a visual indication of the degrees of wear of the tread.
  • Page 50 Tire safety tips. Use this information to make tire safety a regular part of your vehicle maintenance routine. Recognize that the time you spend is minimal compared with the inconvenience and safety consequences of a flat tire or other tire failure.
  • Page 51 1.5.4. S TEPS FOR AINTAINING ROPER RESSURE Step 1: Locate the recommended tire pressure on the vehicle's tire information placard, certification label, or in the owner's manual. Step 2: Record the tire pressure of all tires. Step 3: If the tire pressure is too high in any of the tires, slowly release air by gently pressing on the tire valve stem with the edge of your tire gauge until you get to the correct pressure.
  • Page 52 1.5.9.1. Information on Passenger Vehicle Tires Please refer to the diagram below. The "P" indicates the tire is for passenger vehicles. Next number This three-digit number gives the width in millimeters of the tire from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire.
