DRAG RACE DOUBLE BEAD-LOC TIRE MOUNTING INSTRUCTIONS
Careful care should be taken when mounting and dismounting a tire on a double bead-loc wheel to promote the longevity and the performance of the bead-loc rings.
• Position the wheel completely inside the tire.
• Inspect the tire bead and wheel’s bead flange for any damage, wear, or foreign particles, such as dirt.
• Slide the tire bead onto the wheel’s welded on bead-loc flange. A flat screw driver may be required to assist in this process.
Once the wheel is positioned within the tire and the tire bead is resting on the bead-loc weld-on wheel flange, you are then ready to install the bolt-on bead-loc rings.
NOTE: Installation of the bolt-on bead-loc ring uses a technique similar to that of installing a cylinder head.
• Position the bolt-on ring over the tire bead.
• Prepare each bead-loc bolt with Anti Seize before installing.
• Start 4 bolts by hand in the 12, 6, 3, and 9 o’clock positions. (It may be necessary to use 1.5” long bolts at first to start these 4 bolts and then replace them with the enclosed 1.25” long bolts after the rest of the bolts have been started.)
• Continue to start the remaining bolts by hand.
• Begin tightening each bolt with a speed wrench in a criss-cross pattern until they are “finger tip” tight.
• Continue tightening the speed wrench in a criss-cross pattern until each bolt is “hand” tight.
• Torque each bolt, in the criss-cross style pattern to 50 in/lbs, then 100 in/lbs, and then 150 in/lbs.
• Begin torquing each bolt in a clockwise or counter-clockwise pattern to 175 in/lbs and then to a final torque of 221 in/lbs (18 ft/lbs).
• Once all of the bolts have been tightened to 221 in/lbs (18 ft/lbs) check the torque once more to verify each bolt is at 221 in/lbs (18 ft/lbs).
• Weld Racing advises marking the tire and wheel to check for any tire slippage.
Check the bead-loc bolt torque after your first run and every 5th run after that.
Examine your bead-loc rings during each tire installation. A ring that has a “potato chip” look will not hold the tire bead evenly or as effectively. Weld Racing recommends replacing a bead-loc ring that has this distorted appearance.
