Wheel rims

Due to the popularity of the Off-road tire tutorial, we decided to make another tutorial where we will explain how we made the wheel rims from the finished picture in Off-road tire tutorial.

If you haven’t finished the Off-road tire tutorial, you can get the completed max file here.

Create a line where its vertices have these coordinates in the front viewport (X-axis, Y-axis): 110, 0 ; 0, 0 ; -110, 0.

Move the middle vertex up by 40 units. Right click on that same vertex and choose the Smooth option. Line will now be nice and curvy.

Clone the line, rotate it for 120 degrees and position it like it’s shown in the next picture:

Repeat the same step, but this time position the line to the left.

Select the first line and attach the other two to it.

Create the lines shown red in the picture to connect all 3 curvy lines:

Note: If you create separate lines here, don’t forget to attach them to the main object (3 curvy lines).

Select all the vertices and weld them together.

Apply Edit Poly and Shell (Inner Amount: 0.0, Outer Amount: 10.0) modifiers to the object.

Select the front polygon and by using the Inset tool, inset it for about 5 units. Than, extrude it inwards for -5 units.

Now, we need to move the pivot point so that the completed wheel rim can rotate nicely. To do this, go to the Hierarchy panel and click on the Affect Pivot Only button. Move the pivot point as shown in the picture (move it to the center of the object).

Make a copy of whole object and rotate it for -60 units on the Z axis or until it looks something like this:

Watching from the side, move the cloned object behind the original.

Select the back object and in its modifier stack click on the Line option. Also, select the vertices on the end of its “rays”.

Move the vertices as shown in the picture:

As a last step, add some “nuts and bolts” to the wheel rims to add some detail and realism.

The wheel rims is finished so just combine them with the tire.
