Dick Cepek Wheel Installation and Care

Dick Cepek Tires & Wheels has compiled the information in this instruction sheet from a number of different sources. To the best of our knowledge the information within is correct, but it remains only as a guide. Dick Cepek Tires & Wheels does not assume the responsibility of the installer to ensure the product is being installed correctly. The installer must visually inspect each step of the installment. It is the final judgment of the installer that will determine if a tire and/or wheel has been installed properly on a vehicle.

Installation Instructions


READ COMPLETELY BEFORE ATTEMPTING TO MOUNT TIRES ON WHEELS

Mount tire only according to safe tire mounting practices with proper tire mounting equipment. Careless installation techniques may damage wheels for which Dick Cepek Tires & Wheels cannot assume responsibility.

  1. Test fit each wheel on the vehicle before mounting tires. Never force a wheel to seat against the hub by applying lug pressure. The wheel must go into place freely. Clear the mounting surfaces(axle flanges and/or rotors) of obstructions such as rivets, guide pins, screw fasteners, or spring steel keepers before mounting wheels. If items such as hub or rotor bolts are not removable, consult with Dick Cepek Tech for guidance and corrective action.
  2. In mounting the tire on the wheel, be sure the wheel is properly positioned on the tire mounting equipment and that the hold down cone or rim jaws are secure.
  3. WARNING! Do not use spacers or adapters to resolve any clearance problems between the vehicle and the wheel. If any such item is used the installer assumes all responsibility.
  4. Check for excessive wheel stud length. Excessive stud length could bottom-out in a closed end lug nut thus preventing the wheel from being properly torqued to the drum or Rotor assembly.
  5. Unless otherwise specified on the label attached on the wheel, Dick Cepek Wheels are designed to accept only 60 degree taperedbulge seat conical lug nuts.Do not use any other types of lug nuts or bolts. Verify the thread length of lug nuts with that of the original equipment to ensure properthread engagement.
  6. Do not inflate tire in excess of 60 p.s.i(40 p.s.i. in California)in order to seat the tire on the wheel. If the tire will not seat at these pressures check for any unusual obstruction, proper use of tire mounting lubricants, or possible wheel/tire size mismatch.
  7. Tighten lug nuts in a progressive cross pattern process. Impact wrenches are not recommended due to the possibility of irregular over tightening. Always use the OEM torque specification when tightening wheel lug nuts.
  8. Stud penetration into the hex portion of the lug nut should be in excess of one times the diameter of the stud. All wheel studs should be free of rust and dirt and lightly coated with anti-seize compound.
  9. Use tire manufacturers' rim width recommendations for wheel and tire selection. It is recommended that fender clearance be checked before mounting more than one tire.
  10. Check for proper clearance and true rotation of all wheels before actually releasing the car to the customer.Turn the front wheels from side to side to check for possible interference. Clearance should be checked while the car is on the rack in addition to a final check with the weight of the car applied.Lastly, drive thecar at very slow speeds as final precaution (initially 10 mph max). Re-torqueall of the lugs after the first 25 miles of operation.

DICK CEPEK WHEEL CARE

  • Only wash your wheels when cool using mild soap and water, then hand dry with a soft towel.
  • Some commerical wheel cleaners and soaps, both for home use and at car wash facilities use acid or caustic chemicals and will damage coated wheels.
  • Wash as often as needed to remove brake dust, road dirt and grime before it accumulates on your wheels.
  • When you initially mount your wheels and at least every fourth wash, you should wax them with a wax developed for custom wheels.
  • In regions where salt or sand is used on roads in the winter, the wheels should be removed and stored until winter ends.

COATED WHEEL CARE

Dick Cepek wheels are clear-coated and must be cleaned regularly to retain their original finish. Please wash your wheels (when cool) on a regular basis. Make sure to dry them using a clean, soft terrycloth towel.

DURING THE WINTER MONTHS WE STRONGLY ADVISE CLEANING BE DONE MORE OFTEN IF POSSIBLE.

Dick Cepek would advise the removal of your wheels during this period of time if salt, sand or other corrosive materials are being applied to the roadways in your region.If you are using D-C wheels in regions where any corrosive materials are used on the roads during the winter months, you may consider applying a sealer or petroleum based protectant to the face of the wheel.

NOTE: POOR FINISH DUE TO THE LACK OF MAINTENANCE IS NOT A WARRANTABLE REASON FOR RETURN AND WILL NOT BE ACCEPTED.
