I've made a couple of aftermarket truck tire sets and they have been well-received, so I thank everyone who has supported me with that. One of the things that has always bugged me about scale model car and truck tires is that they don't portray the appearance of the real thing. Real tires bear the weight of the vehicle, and this shows up as a slight bulge at the contact patch. This bulging is mostly seen with radial tires. Aircraft modelers have realized this shortcoming in their models for years, and some of the very first resin aircraft items that appeared were weighted tires. Sanding the bottom of a round tire flat helps, but can't give you the bulge that conveys realism. I've made up a bulged version of a new 3D tire model:
Here are two weighted tires alongside the un-weighted tire (right). I am thinking of selling this new tire in a set of five tires: four weighted tires and one un-weighted tire to use as the spare. The initial costs to do this kind of set are higher than a typical tire set, since it requires at least two masters instead of just one. Is this something that you truck modelers would like to see?
