Frequently asked questions.
PRE-INSPECTION AND INSTALLATION
Inspect the wheels immediately upon receipt and before mounting tires. Once tires have been mounted, the wheels cannot be returned for credit. Verify that the wheels have the correct finish, bolt pattern, center bore diameter, ample brake caliper clearance and the proper backspace or offset for your vehicle. ALL OF THIS MUST BE VERIFIED BEFORE MOUNTING TIRES ON THE WHEELS.
Use only tires consistent with the vehicle manufacturer’s recommended sizes for the wheels you have chosen. Using tires that do not conform to the vehicle or tire manufacturer’s recommendations may result in serious safety issues related to undersized or oversized fitments. Modified Concepts IS NOT RESPONSIBLE for damage related to incorrect tire sizes such as vehicle transmission, AWD systems, body panels/trims, or other effected areas.
Before mounting tires, the tire bead seat area should be generously lubricated.
Mount the tires using only TOUCHLESS tire mounting machines.
Use STICK-ON WEIGHTS ONLY.
After the wheels and tires have been placed on the car, take a short test drive. Re-check the torque values of each lug nut/bolt and make sure that they are torqued to the manufacturer’s recommended specifications.
If you intend to use one of your original equipment wheels as a spare, make sure that you keep a set of the correct lug nuts/bolts and a properly sized lug wrench in the car at all times.
LONG-TERM WHEEL CARE
3-Piece Wheels - Under no circumstances should you or anyone else loosen or remove any of the wheel assembly bolts. When the tires are installed and under pressure, removing the assembly bolts can lead to serious injury or even death. Removing assembly bolts will automatically void the warranty on the wheels. The assembly fasteners are structural, not decorative. Loosening them could lead to catastrophic wheel failure during disassembly or use, resulting in serious injury or death.
To keep your wheels looking like new, regular cleaning is highly recommended, and in adverse weather climates where salt or chemicals are used on the roads, it is mandatory in order to maintain the finish warranty on your wheels. Please follow these guidelines:
Never use any chemical-based cleaners or harsh cleaning solutions.
Use only mild soap and water with a soft, non-abrasive cloth rag to clean the wheels of dirt and debris.
Spray-on, hose off type cleaners are strictly prohibited
Do not clean the wheels when they are still warm from operation of the vehicle – allow them to cool before attempting to even hose off. Cleaning them in shade is highly recommended.
You can apply a soft paste, spray on wax or ceramic coating to your wheels to ease maintenance and improve wheel appearance on clear-coated, painted or chrome wheels; this is not advised for unprotected polished surfaces.
Wheel Storage
Always clean wheels before storing.
The best place to store your wheels is in a plastic bag or wheel and tire storage bags. Do not store your exposed wheels or tires on bare concrete.
If left on the tires, stack them on their side up to 4 wheels high. It is helpful to place a clean sheet of cardboard between each wheel and tire bag to stabilize and prevent accidental metal-to-metal damage.
If minor damage occurs on your wheels, such as light curbing, you can always contact a Modified Concepts Representative to discuss refinishing options at (516)742-8200 or You can also contact a local wheel repair specialist to repair minor damage while maintaining your Warranty. Repairs involving light sanding and color correction will retain your Wheel's original warranty.
