1:8 Scale Trailer Tires, Rims, and Hubs

[MarkC.]

Hey All!,
I'm new here and I'm into 1:8 scale trains. Here shortly, I'll be building a "Spine Car" that will transport a 1:8 scale 45 ft. road trailer as a static load just like the railroads used to do. The first part of this build will involve building the trailer. I've already worked out the logistics of tires, rims, and hubs for the trailer. Using silicone molds...I've molded just the rims. I have other molds, I've made, that will mold a truck tire to the rim. It's a process I'm steadily improving and uses various types of 2 part polyurethane. I'm looking to see if any of you all have built similar truck parts, trailers, or semi trucks in this scale. In time I hope to make these tire / rim / hub assemblies available for sale to the hobby. I know tires, rims, and hubs are available for purchase in Germany but the cost of each is very high. I plan on making my tire assemblies available at more reasonable costs. In this post....I'm looking for feedback from any of you who are getting into RC Semi-Trucks in this scale. Any feedback would be greatly appreciated. Sorry....I'm still learning how to post photo here. Any help in how I can post photos would really be appreciated as well.
