I started my own Website for PBR textures. All the materials on there are licensed under the Creative Commons CC0 License, so you can use them for whatever you want!
The people on Reddit absolutely love it so I thought I would also post it over here. I hope you can get some use out of them.

Thank you for creating and sharing this, materials look great! Here is the website link inline: www.cc0textures.com
A suggestion: Consider creating categories section.
Yeah, I am already working on an overview page with all the categories.
A free texture site? Perfect!
I will definitely use it for many future artworks and projects. Thank you for sharing it!
