Firestone Logger Service LS-2/LS-3 Tire/Rim Usage

Date: AUGUST, 1991

NOTE:This bulletin replaces Field Engineering Tip #38A dated May, 1989. Firestone logger service tires have different bead widths depending on size of tire and ply rating. Rim bead seat ledges must be wide enough to accommodate the entire bead width of a tire for trouble-free services; in some cases, that means a different rim for a particular tire size and ply rating. Rims with inadequate bead seat ledge width for the tire bead allow the tire bead toe to extend beyond the rim bead seat ledge, which can chafe the tube leading to air loss, downtime and loss of production.
