Thanks to this forum and my research, the following is what I am going to use for my concrete garage floor. Please comment or make suggestions to help me:
Porcelain
12 X 24 because it is most common and larger might crack easier
Rectified - yes (all edges are cut to insure squareness)
PIE rating of 4 or 5 (highest scratch resistance)
Vitrified - Not sure if this is necessary or applicable to porcelain tile
Through body or colored body - colored body because through body is hard to get and my be expensive (not sure of this)
Slip resistance - rating of R11 through R13
Glazed but not polished
