Tire Pressure Set By Dealer

[MisterG]

Hello,

 

Newbie to the group here, sorry if someone posted this before.     I recently took my 2017 Fusion Hybrid into a Ford dealer for service, and when I got the car back the tire pressure had been adjusted.     The rears were set to be 2-3 lbs lower than the front.    In everyone's experience is this a good practice?    I for one have always assumed for best fuel economy that all tires should be set to the same PSI.      I'm not so much looking for advice on what PSI to inflate my tires to (there are several posts about that), but I was more curious about the practice of making the rears less than the fronts.     What have you all seen and what do you feel is the best way to go from a front vs back perspective?

 

I can obviously change the PSI myself, but did not know if there was some benefit to the driving experience or to the MPG by deflating the rear tires in such a manner.

 

Any feedback would be welcome....

The recommended tire pressure is on a sticker on the driver's door opening.  I no longer have a Fusion but all 4 tires were the same pressure on the one that I had.

Are you sure the pressure had been adjusted?  It's winter and changing temperatures will change the pressure.  They change 1 psi for each 10 degree F change in temperature.

No, all 4 should be set the same.

Ford says 35 PSI on the cars.  I run 40 cold because I'm lazy and it takes longer for me to feel like checking tire pressure - especially in Winter. 

 

Make sure you're check ing cold pressure.  The TPMS stuff may vary 1 or 2 PSI between them, so they aren't always all that accurate.  I have one that registers 2 under what the pressure really is.

Thanks to all for the reply!    It does seem odd that the dealer did this, but will be setting all of them the same!
