Since we are expecting snow, I thought this would be a good time to check all of the tires. With the varying feedback it will hopefully provide better insight.

My iDrive screen prior to the test showed green all the way around and each tire was between 35-36psi. I let air out of the front passenger side and once it got to 27psi it displayed as low on the iDrive screen. The center gauge cluster showed the tire light but had no indication of which tire as I previously mentioned. I filled it back up and it returned to green once it got back above the 35psi setting. Pics attached.

Question...the recommended cold pressures are 33psi fronts and 39psi rears. Should I follow this exactly or is 35psi fronts and 36psi rears sufficient. Will it noticeably affect anything? Thanks.
