USER’S GUIDE
Thank you for purchasing our product. Before installing wheel,
please go over this instruction manual thoroughly to ensure proper
safety and performance of the wheel.
Pre Installation
Match specifications on wheel with packaging label, and physically
check-fit wheel on vehicle before mounting tire.
Items to check:
• Center/hub bore diameter
• Brake clearance - Caliper and rotor
• PCD or bolt pattern
• Offset or E.T.
SHOP INSTALLER
Please pass this instruction manual to customer after reading.
• • •
Tire mounted wheel is not exchangeable or returnable in
any condition.

Tire Pressure Monitoring Sensor (TPMS)
All passenger vehicles with post, and some prior to, September 2007
production date are equipped with Tire Pressure Monitoring Sensor
or TPMS system. It consists of a sensor for each wheel and a
receiver located somewhere in your dashboard. In order for the
system to perform correctly, you need to transfer all four sensors from
factory wheels to NM RSe wheels. Depending on year and model,
some TPMS systems may require software reset that can only be
done by dealership. Make sure to notify the installer if your car is
equipped with TPMS. Refer to your car-operating manual or your
local service advisor for additional information.
Wheel Installation
Note that RSe wheels utilize OEM lug bolts with 60 degree conical or
taper seat. If aftermarket lug bolts are planned to be used, make sure
they have the following specification:
(A) Socket Size: 17mm
(B) Seat: Conical - 60˚
(C) Stud: 14mm x 1.25
(D) Stud Length: 27-32mm
When tightening lug bolts, avoid using impact wrench or air gun. Fast
speed and high torque spin produced by impact wrench can cause
cross thread and damage hub carrier.
Tightening Spec:
Lug torque
: 125 N-m (90 Lbs-ft)
Socket size
: 17mm
Sequence
: See illustration
> All NM RSe wheels are TPMS
compatible.
Check lug bolt torque frequently. Failure to use proper lug bolts
with sufficient torque load will result wheel coming loose and
detached while driving causing accident.
Post Installation
Wheel lug bolts will settle and loosen up after initial installation.
Retighten after the first 50-60 miles to specification.
If your car is equipped with tire pressure monitoring sensors,
check them by deflating tires to bellow the default threshold
to test if they are working as they should. If your car is not
equipped with TPMS, check your tire pressures periodically to
make sure there isn’t any leakage.
Maintenance and Storage
•
Periodically check lug bolt torque load; ideally Every 1000
miles or if you feel that you just ran over a sizable bump on
the road.
•
Aluminum alloy wheels are susceptible to oxidation when
they are exposed to salt or mud. Wash with water after driving
on beach, snowy or unpaved road.
•
During hard driving, heat generated by the brake rotor and
caliper transfers to wheel. Avoid exposing hot wheel with
water since it may cause coating/finish damage or cracks.
Wait until everything cools down before proceeding.
•
Do not use abrasive chemical with strong acid or alkaline
for cleaning agent. Please use diluted soap water or specific
wheel cleaner (not for chrome finish) with soft cloth to wash
and clean wheel. Do not use metal brush, brill pads, scotch
brite, or other similar coarse products. Soft tooth or bristol
brushes are ideal to clean off dirt from tight corners. Rinse
with clean and ambient temperature water.
•
Rinse dirt/dust using ambient temperature water from garden
hose. The use of pressure washer is not recommended
especially the gas powered commercial model.
•
When storing for prolonged period of time, keep wheel/tire
away from direct sunlight, rain, oil, humidity, and heat.
Reducing tire pressure to half (1/2) during storage is also
recommended.
•
When reinstalling on vehicle, re-check tire pressure and
balance. Also inspect lug bolts for: correct lug seat, thread
condition, hex-head corners, and overall surface. Make sure
there is not any damage. Damaged lug bolt can cause further
damage towards hub and improper fitting, which may cause
wheel coming loose while driving. Torque to correct spec.
