Thanks Lexypobi. Um, I am not really someone to teach anyone because I am learning too. Mostly just trial and error kinda thing. I prolly did it the hard way too.
I took some polys from the rim and made a basic tire from it. Hit the ‘d’ key to add more geomtry to it while deleted any unwanted loops I don’t need. Selected the polys in the pattern I wanted then beveled them inward. Then added some loops to the inside of the tread. Used a linear falloff and rotated the tire a little. Then mirrored it.
An easier way I heard is to start with flat plane, make the pattern and bevel. Clone it a number of times and merge the verts. Then bend it 360. Mirror it. Serve with beer.
I have seen alot of treads done without sub-d, that might be a better way to go.
Like I said, I am too much of a novice to really give advise but I like to help. So maybe someone else can correct my lack of knowledge.
Hope it helps.
