Ok I had a little time , about an hour to make this. If I knew what I was doing it would have been about 10 min!!! Not sure about how to make a negative mould. It may be better for me to make a scale tire, trim sand the plastic tire and then make the mould from that. It's just a start to see if I can do it. The treds will be more accurate on final but it's a start.

What software is this?

Make your master in the printer . Clean it up smooth it if necessary . Then make a mold and cast them like Tom did . I made the negative of the tire for machining the mold , but I forget what I did . I have 2004 autocad

That's what I think I'm going to do, make a master that I will be able to clean up the lines from printer. Then make a negative. Still researching what silicone to use. Rtv with pigment for final. Not sure what hardness, looks like around 60? Still not too knowledgable on that part. Like I said another thing to learn how to do!! So far in this hobby I'm a machinist, designer, frabricator, metalergist , ect,,,, and still don't know any of that stuff!! Would make a heck of a resume, until I got hired and didn't know squat!!! what hardness are those tires on your loader? A little soft if I remember but they are holding up great. (Kind of felt like some surgical implants . ) lol.
Once I figure out what I'm doing I'll get more precise with tread pattern. I'm sure a few "oops" will be along the way. But if they turn out I might be able to make a few for others? Do you know what products were used in the making of the actual tire? Rtv silicone? Pigment?

look for modelman's (Tom) 777 thread , he goes over the whole tire making . Or he'll see this and help you out .

I know my loader tires are made from latex rubber . you'll see it again on sunday . I got er checked out and greased for werk

The free stuff, autodesk123 design. I'm not too knowledgable with this stuff but from what I've found it works to an extent. From what I researched most are making a extrusion for treads on a different layer but with this I can't do that so I used the circular pattern and just increased the number till treds looked full.
