Tool--I forgot to mention in my original post that I have a 2016.5 Grand touring with the 19 inch rims. Not sure what yours are, that might explain the difference between our recommended manufacturer psi for our tires.
Im betting all the CX5s are shipped over with higher than normal tire air pressures for some explainable reason. Makes me wonder how many people passed up on a great little suv because this created a stiff ride.
