As requested, here are the Firestone tires to replace the VRC default ones. More realistic, better specular and more of a worn look. Eventually I'll redo the 1999 and 2012 to match.
Light/shader patch compatible. Just make sure to install BOTH "content" and "extension" folders, if you are not running the light/shader patch, you dont need the extension folder.
Enjoy, and feel free to use in all your skin projects!
