Q1.What
is a Center Bore?
The center bore of a
wheel is the size of the machined hole on the back of the wheel that centers
the wheel properly on the hub of the car. Center bores on wheels are typically
a standard size by brand or size (measured in inches or mm).
Q2. How
many wheel finishes are there?
Hereunder
is the list of the abreveation of the finishes we commonly know in wheels
styling.
S: Silver
W: White
B: Black
GM: Gun
Metal
EMC: Bling
Bling Chrome
EMB: Bling
Bling Black
ML: Mchine
Lip
SSR: Stainless
Steel Rim(Inox)
HS: Hyper
Silver
HB: Hyper
Black
CL: Color
line on rim edge
MS: Machine
Face
MS/B:
Machine Hyper/Black
MS/S:
Machine Hyper/Silver
Q3. Is
Riverts, Nut, Bolt and Hub Ring or Valve included in the wheel that I
purchased?
All these
accessories are subjected to separated order. In many cases.
Q4. What
is Plus Sizing?
In short,
it is designed to enhance vehicle performance and looks by allowing
fitment of larger diameter rims and lower profile tires.
There are
two rule to abide for Plus Sizing.
Plus 1:
Increase section width by 10mm
Decrease aspect ratio by 10 points
Increase rim diameter by 1 inch
Plus 2:
Increase section width by 20mm
Decrease aspect ratio by 20 points
Increase rim diameter by 2 inches.
Q5. How do I calculate the Offset of a Wheel
To begin
with it, measure the overall width of the wheel. Next, divide that width of the
wheel by two; this will give you the centerline of the wheel.
Overall width/2 = Centerline
After determining the centerline, measure from the mounting pad to the edge of the inboard flange (if the wheel were laying flat on the ground
– face up – your measurement would be from the ground to the mounting pad).
This is your back spacing.
Centerline – Back Spacing = Offset in Inches
Inches x 25.4 = Offset in mm
All of the wheels in the American Racing catalog indicate the wheel’s offset.
Q6. How to determine the Right Offset
for my car?
Short of
adding fender flares or a body kit to your car or rolling and pulling your
fenderwells, there is no way to significantly change your car’s offset. If your
car has a high offset, you will have to buy a high offset aftermarket wheel. If
you car has a low offset, you will need a low offset aftermarket wheel.
Typically, front wheel drive vehicles have a high offset (+35 mm or greater), and rear-wheel drive applications will have lower offsets (this is not true in all cases, as the Honda S2000 is rear wheel drive, and has a very high
offset). Your installer or tire and wheel dealer should be able to tell you what
the offset of your vehicle is.
The common definitions are:
Low – 0-15 mm
Mid – 16-34 mm
High – 35-40 mm
High + - 41+ mm
Other factors in determining what offset is right for your vehicle is whether
not you are making any other changes to your car (lowering or raising,
aftermarket brakes, etc.).
If the offset of the wheel is not correct for the car, the handling can be
adversely affected. When the width of the wheel changes, the offset also
changes numerically. If the offset were to stay the same while you added width,
the additional width would be split evenly between the inside and outside. For
most cars, this won't work correctly.
Q7. How do I care for my wheels?
Here are a few pointers for
caring your wheels:
1.Do not use household cleaners or detergents to clean your wheels. The best
cleaning solution is mild soap and water solution.
2. Does not use steam cleaners in automatic car washes.
3.Clean wheel when they are cool.
4.Clean one wheel at a time.
5. After the wheels are clean and dry, apply one coat of wax to them.
Q8.What is the difference between casting
wheels and forging wheels?
Casting wheels have the
advantage of allowing the designer more styling freedom because the process is
a more flexible method. Forging wheels, however are limited in shape and overall
cost usually higher than casting. Most modern performance wheels are made from casting
with high production rate and design flexibility. |
