REMA Radial Repair Units are known as COI (Center-Over-Injury), however, beginning with their product, RAD 120 through the largest Repair Unit they can be shifted “Radial direction only” (See images below), to avoid placement in the high flex areas in shoulder areas and the sidewall. REMA provides templates on the back of each repair unit boxes to aid in the best tire repair unit placement.
The anchor areas, 25%, of each end of the repair unit, should never be positioned in the high-flex sidewall zone of the tire. Doing so can jeopardize the bond integrity due to “shear” force on the repair unit. Templates provided on the boxes can be used to identify this “shift” area so that the exact tracing of the unit can be indicated on the tire liner.
The repair unit should not be installed any closer to the Bead Toe than 3/8 inches.
Should and Sidewall injuries generally require one anchor point in the crown area and the other anchor point near the bead area of the tire. This rule can sometimes cause up-sizing the repair unit size, to gain additional length, to accomplish proper placement.
Crown injuries can generally have repair units placed in the center of the interior crown area of the tire.
