From the top-left:
1. Cylinder initialized with a center radius, and specific polygons selected with masking. (A torus can be used instead.)
2. size down (or up) and remove mask.
3. Divide 2 or 3 times, smoothing either inbetween each divide, or several times after dividing. Smoothing inbetween divides will make the tread shapes very smooth and rounded. Smoothing after the divides will create a blockier tread with small radii at the edges.
4. Perform various Deformations such as Radial Flatten, Spherical Flatten, and Spherize. Unwanted distortion can often be Smoothed out.
5. Mask one half of the tire and Twist 25 to 100%. Invert the mask and Twist in the opposite direction the same amount.
6. One or more center grooves can be created by dragging a selection mask around a strip of polygons in the middle of the tire. Invert the mask so that the strip of polygons are unmasked. Size down or twist to create the groove.
7. Selection of one half of the tire or a strip of polygons on the center-line of the tire is very easy. Select Alpha Brush #00, set Alpha:Blur to zero, hold the Control key down, and start dragging in an open area (not on the tire). A selection box will appear. Drag this around the polygons you want to select.
