CRF Run Flat Tire Inserts: Installation



#1 Inspect Wheel before Installing...Clean wheel and install "Metal Valve" supplied with your order.

#2 Ensure that the " CRF" Will properly fit your Wheel !! Position "CRF" arcs against Wheel and confirm they are properly mated. Install bolts to ensure "CRF" is secure to Wheel drop center; continue to tighten bolts until joint faces are togethe. For additional tightness, rotate one or both washers 180 degrees as needed.



#3 Insert the two "Arcs" into tire with flanges and washers facing up. Apply Locktite to bolt threads. Connect "Arcs" loosely with one bolt... As shown in photo below.



The Bulldog Direct "CRF" is NOT a run flat tire like [ Goodyear and Firestone's] run flat tires ; BUT! a tire rim insert that is custom manufactured to fit your  vehicle tire rim. Manufactured from a lightweight Space Age Ballistic Composite and balanced during manufacture, it will not create any tire-wheel imbalances.  Use your existing tires and rims!!



#4 Fit inboard tire bead and "CRF" on your Wheel and allow "CRF" to move into the wheel's drop center.



#5 With outboard tire bead on outside of Wheel flange, place steel mounting rods [ mounting kit provided with your order] in the 1/2" holes provided on each side of the "CRF". Slip
adjustment band over mounting rods.  Laterally spread rods at top, closing the "CRF".
Install the remaining bolt, apply Locktite to bolt threads and tighten all bolts and torque to 50 ft. lbs. Installation takes about 20 minutes per Wheel. 



#6  Secure mechanical lock over all connection bolts.  Attach with Phillip's head screws provided.  Mount outboard tire bead and inflate tire to manufacturer's recommended pressure for load carried.  Re-Balance finished assembly, and your done!!!
