CRF Run Flat Tire Insert installation process

#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 together. For additional tightness, rotate one or both washers 180 degrees as needed.

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!

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.
