Step 32: Now its time to create the treads go to front view and create a cube with the same settings as below
Step 33: Go to vertex mode and move the vertices like the image below
Step 34:Duplicate the top tread and bring it to bottom then create 2 more cubes in between like the picture showing you below.
Note: you are more then welcome if you like to bevel the edges of treads to give it more detail
Step 35: With the all treads selected and combine them as below
Step 36: With the treads selected go to (Edit>>Duplicate Special Option Box) and then in the rotation Y Axis give the value of 9 and in the number of copies put the value of 40 as below in the last hit duplicate special.
Step 37: Now your treads should copied around the tire nicely like the image showing below
Step 38: For the empty place create another new Pipe with the settings as below and place it nicely between the treads
Now overall tire will looking like this...
Here we are done with our tire, to add more detail around the tire you can use the following bump map
I just add the bump map then applied cylindrical UV texturing and took a snapshot of it and bring it to Photoshop to fix the errors and then saved my image and in the last I applied as bump map. as you can see I added a break disk I don't feel it necessary to explain, since its pretty easy to model if you familiar with modeling tools in Maya.
