Texture problem when applying to procedural mesh

I am currently writing a tilemap system in which the map is required to generate at runtime and also have a procedural texture applied. The Mesh generates perfectly and the texture almost fits the mesh but is 1 pixel greater than the set tilesize.

I have messed around with the variables to see if it was just a mesh or texture scaling problem but it appears not.

Notice that the texture squares are not the same size as the grid AND that they go over the edge of the texture due to appearing to be 1 pixel to large.

When I save the texture onto my hard-drive however, it is 8 * 8. (The image is fuzzy (When uploaded onto this site (it isn't in Unity)) so I will not upload an example of it).

The most obvious solution I can think of then is scaling the image down to fit the entire board but A. I don't know how. B. I don't know how efficient that is. C. It seems like a cheap workaround. (Right now I am generating an 8 * 8 grid on the X / Y Axis)

 void BuildTexture(int size_x, int size_y) //Pass In number of tiles
     {
         int texWidth = size_x * Tile.resolution; //Resolution is currently 1 so the math here is simply 8 * 1
         int texHeight = size_y * Tile.resolution;
 
         Texture2D texture = new Texture2D (texWidth, texHeight); //Create Texture
 
         for(int x = 0; x < texWidth; x++) //Loop through texture
         {
             for(int y = 0; y < texHeight; y++)
             {
                 Color c = new Color(Random.Range(0f, 1f), Random.Range(0f, 1f), Random.Range(0f, 1f)); //get Random Color
                 texture.SetPixel(x, y, c); //I am aware that this is inefficient, this is a standin system to fix the current tiling issues
             }
         }
 
         texture.wrapMode = TextureWrapMode.Clamp; //I heard this was useful for preventing this problem... It wasn't
         texture.filterMode = FilterMode.Point; //To prevent fuzzy textures
 
         texture.Apply (); //...
 
         meshRenderer.sharedMaterial.mainTexture = texture; //Apply Texture
     }

It is also important to note that I do not receive any error messages.
