GENERAL INSTRUCTIONS PART 1: SAFETY – MOUNTING THE TIRE IMPORTANT: BE SURE TO READ THIS SAFETY INFORMATION. Make sure that everyone who services tires or vehicles in your operation has read and understands these warnings. SERIOUS INJURY OR DEATH CAN RESULT FROM FAILURE TO FOLLOW SAFETY WARNINGS.
ZIPPER RUPTURES TIRE INSPECTION A fatigue-related damage, with or without a rupture, occurs in the sidewall flex area of steel radial light and medium truck tires when it is subjected to excessive flexing or heat. This zipper rupture is a spontaneous burst of compressed gas, and the resulting rupture can range in length anywhere from 12 inches to 3 feet circumferentially around the tire.
PART 2: MOUNTING AND DEMOUNTING TUBELESS TIRES In order for a tire to perform properly, it must be mounted on the correct size wheel. The following are general instructions for mounting and demounting BFGoodrich® Truck tubeless tires. Specifics for 19.5” wheels are detailed in the Mounting Tubeless Tire section (Page 5). For additional detailed instructions on mounting and demounting truck tires on particular types of wheels, refer to the instructions of the wheel manufacturer or the RMA wall charts.
contamination and prevent excess lubricant from entering the tire casing: provide a special cover for the portable container that has a funnel-like device attached. The small opening of the funnel should be sized so that when a swab is inserted through the opening into the reserve of lubricant and then withdrawn, the swab is compressed, removing excess lubricant. This allows the cover to be left in place providing added protection.
DEMOUNTING OF TUBELESS TIRES If bead(s) did not seat, deflate tire, re-lubricate the bead seats and re-inflate. Note: As a general guide in vibration analysis, the 30/60/90 rule may apply: .030-.060 (1⁄ 32 to 2 ⁄ 32 inch) = No action is required. Limited possibility for vibration exists, and this range maximizes the ability to balance properly. .061-.090 (2 ⁄ 32 to 3⁄ 32 inch) = Corrective action would be to perform the 3 R’s, after deflating the tire.
PART 3: MOUNTING AND DEMOUNTING TUBE-TYPE TIRES A tire cannot perform properly unless it is mounted properly on the correct size wheel. The following are general instructions for demounting and mounting BFGoodrich® tube-type tires. For detailed instructions on mounting and demounting truck tires on particular types of wheels, refer to the instructions of the wheel manufacturer or the RMA wall charts. Do not re-inflate any tires that have been run underinflated or flat without careful inspection for damage.
the funnel should be sized so that when a swab is inserted through the opening into the reserve of lubricant and then withdrawn, the swab is compressed, removing excess lubricant. This allows the cover to be left in place providing added protection. A mesh false bottom in the container is a further protection against contaminants. The tire should be mounted and inflated promptly before lubricant dries. 1.
5. Close the beads. 6. Apply a proper tire lubricant to the inside and outside surfaces of both beads and to that portion of the flap that appears between the beads. Make sure that excess lubricant does not run down into the tire. 7. Follow Steps 4 through 8 of the “Mounting of Tube-Type Tires.” 1. Insert the proper size tube into the tire and partially inflate (3 psi) to round out the tube (with larger sizes it may be necessary to use bead spreaders – see below for mounting instructions). 2.
