Read
this first!:
Like many other methods in
Photoshop, there is usually more than one. This is just
one.

Alright!
We are going to take the wheels off the black car, and then put
them on the blue car and hopefully at the same time achieve an
effect of realism.
|

First
we are going to replace the front wheel. So make a
selection around the front wheel of the black car using the
ellipse selection tool.
If you don't get the selection right the first time, fear not!
Simply go:
-Selection
-Transform Selection
Drag the edges/corners as necessary.
Press "Enter" when you are done.
TIP:
Try
and select a little bit of the black tire around the rim, it may
help out a little later.
Now go:
"Edit - Copy"
then click on the canvas with the blue car and go:
"Edit - Paste"
Now we have a wheel to work with.
Tools used this
step:
Ellipse Marquee

Since
our cars were facing the opposite direction, we'll have to make
it so the wheels appear to be going the same way; and here's
how:
After you've made your selection, go:
-Edit
-Transform
-Flip Horizontal
This will make
the wheel face the right way. Now you'll see the wheel is
not the right size and is much bigger than the rim we want to
replace. Time for a little resizing . . .

While
you have the layer with the wheel selected, go
"Edit - Transform"
and drag the various points of the box so that your
wheel covers up the existing wheel.
See how that extra black around the rim is paying off
from a few steps ago?
TIP:
Hold
down "Shift" while dragging to keep
your wheel scaling equally.
(also known as "constraining".

Now
you'll notice that some of your wheel overlaps the front fender
of the car. To fix this, simply use the polygon lasso and
trace the edge of the fender (its easier to do if you turn off
the visibility of the wheel layer).
Then (while the
wheel layer is selected and visible) simply press the delete
key! Now your wheel doesn't overlap anything that its not
supposed to.

Now
that should ALMOST do it for our front rim conversion. We just
need to match the rim's colors/hue/brightness to match the
picture we dropped it in. This wheel is pretty close
already, but it looks like it could be a little more shiny.
So to do that I am going to go:
-Image
-Adjust
-Levels
Then drag the far right arrow to the left a little bit.
You'll see the wheel get brighter without distorting it to much
unlike what the "Brightness/Contrast" option does. |
|
|
 |
We're
going to repeat the same steps to swap out the rear wheel.
You may have to scale the wheel a little more and do some more
transforming (such as rotating and scaling horizontally).
You can see
here both black and blue cars with the same rim now.
TIP:
I added a hint of blue and cyan to match the setting of the blue
car. To do this go:
-Image
-Adjust
-Color Balance

ta-da!
Where have our blue car sportin' some 18" Racing Hart C5
rims.
(The original
rims on the blue car were 17" Konig DTMs if you're
wondering)

TIPS:
-
Try avoiding rims like the ones below: Why? Because it
doesnt have any rotors/brakes! It will look quite funny if
you put these rims on a car.
