Unity mobile game wheels with substance pack

Hello,
I'm planning on realeasing a mobile game wheel pack for unity with Substance option.
So, every wheel will have arround 350 tris with a PBR substance or a Albedo texture.
The albedo texture will be optimized to be used on resolutions of a minimum 64x64 res.
The default resolution for all textures will be 2048x2048, so users can choose what fits them best.
I am mostly adding the substance so it can be used in menus(get some cool reflections, normal details), so far every wheel looks really awesome with the substance applied so it can be used for closeups in menus.
The albedo only texture is also looking awesome. Down you can see some wheels that i made.
Note: The images are only using the albedo version. I feel like that was the hardest to get right.

I am planning on making arround 15-30 wheels. I am trying to not have to many look the same. I am making from trucks, muscle cars, sports cars, everyday cars.
