Now we can duplicate a segment using a binding to a point. Press Ctrl D and keeping key V, at moving we can precisely combine necessary vertexes:

Now it is necessary to repeat this action necessary quantity of times, all depends on that how much big you wish to make a wheel. I have made 12 segments

Now we select all segments, and we come into menu Polygon and we execute command Combine. Now it is necessary for us to turn the given design into a ring. For this purpose it is switched in mode Animation and it is chosen Deform/Create Nonlinear/Bend:

Apparently, on the screen has appeared handle which allows to specify a direction and force of a bend precisely. Rotating the handle and having specified in the panel of channels necessary value of parameters of the deformer:

Parameters Low and High Bound are responsible for length of the bending ends. Now try to set such value of parameter Curvature that the ends of our tire cover were closed. Increase on the screen a junction of the ends of a tire cover and try to enter such value that vertexes have coincided:

Then we connect vertexes of segments Edit Polygon / MergeVertex.

We delete history Edit / Delete by Tape / Hestory also we fill lateral holes Edit Polygon / Fill Hol

And using tool Edit Polygon / Extrude Face it is finished our tire cover:

Do not forget to remove internal faces and to smooth model Polygon / Smooth

The following part of a lesson is devoted more to experienced users, various technological aspects  therefore will not be mentioned. Let's produce a plastic bottle for water.
