... and probably counting.
Lug nut size: 21mm
Torque: 108-147 Nm, or 80-108 ft-lbf (for both P225/65R17 100H and P225/55R19 99V)
Tire pressure: 34psi(17") / 36psi(19")
Good for me since my previous car was a Elantra 2007 which have the exact same size lug nut. I don't have to buy another socket.
edit: I rotated my tires on my cx-5 yesterday, when I was unbolting the lug nut, it felt close to 80 than 90 ft-lbf. I used 90 ft-lbf this time, but I'm going to use 80 from now on.
