I go with 39 psi cold too for all four 19 tires mainly for even tread wear to maximize the tire life. My experience on one-number-fit-all manufacture recommended tire pressure for US market is its usually a bit too low which wears out the outer sides of tread faster. Tire pressure should be flexible depending on many variables: tire type、brand (design characteristic)、temperature、speed、and load. For those who believe we should follow Mazda recommended tire pressure with 35 psi (36 for gen-1 CX-5) on 19 tires, see the different tire pressure recommendations for CX-5 from UKs 2017 CX-5 Owners Manual with wide range from 36 to 42 psi depending on load. One example even recommends 45 psi on winter tires!Going with 39#, thanks for opinions. Been working on cars for over 65 years, it never hurts to get the latest opinions!!
Not necessary. Many CX-5 owners here use 2~3 psi higher than recommended tire pressure with no wear issues. Mazda itself recommends higher tire pressure than US recommended tire pressure in other countries for different load conditions....and wear out the tires' center, faster.Typically, if you go higher than the factory recommended spec, you'll get improved mileage while sacrificing traction and increasing the risk of tire, rim or suspension damage when you hit potholes or curbs.
I agree with shadonoz. Higher than the factory recommended tire pressure, especially the one-number-fit-all US spec, should decrease the risk of tire, rim or suspension damage when you hit potholes or curbs.Just the opposite. Lower pressure increases those dangers.Typically, if you go higher than the factory recommended spec, you'll get improved mileage while sacrificing traction and increasing the risk of tire, rim or suspension damage when you hit potholes or curbs.

My statement is based on overinflating too much (like 15-20 psi vs. 3-5 psi).
