I've decided to add my 2cents worth.
I ran my factory fitted 205/55/r16 @ 40psi for 40,000kms without any issues or disaster, even tho the tyre placard stated 35psi front & 33psi rear.
I ran two sets of 225/45/17 Hankook's on the same BL Mazda 3 at 40psi for 75,000kms also with any issues or disaster.
Yes the ride was probably harder than running 33 or 35psi, but I was happy with the car.
The number of times I see customers cars come thru work at 28, 30 psi & they ask why their tyres only lasted 20 or 30,000kms.
I would rather see tyres 2 or 3 psi above the label vs tyres at 28 or 30psi.
As mention before, our dealership sets CX-5 tyres at 38psi & I'm not aware of any issues, complaints or failures.
Callisto, I think you need to get off your high horse and accept defeat.

Interestingly enough, my MX5 has recommended pressure of 29. I do know that if you vary more than a couple of pounds from that, handling and ride change dramatically. The problem that I have had is shops wanting to put 32 psi in the Mazdas where the CX5 recommends more than that and the MX5 less. It seems the CX5 is always giving me the low tire warning after service.

Bumping an older thread here to write that my son's 2021 CX-5 came home from the dealer store with all four tires filled at 44 to 45 PSI. The ride seemed too hard/firm so I lowered each tire to 39 PSI.
I guess the dealer store employee fills the tires with so much pressure because it makes for a more sporty handling ride ?

Dealership do not over inflate tires to prevent flat spots. That would create an unsafe vehicle specifically for test driving and I think the insurance carrier for the dealer ship not to mention state laws would frown on such practices?

They SHIP the cars with overinflated tires. This has been discussed many times. They are supposed to adjust the pressures to what the door placard states during the PDI, but some dealers don't do so well at this. Mine had no PDI done at all. None of the paperwork was filled out when I emptied the glove box. All tires were close to 50PSI.

This would actually reduce the handling characteristics of the vehicle in some situations, so I doubt it was for the purpose of making drivers and passenger fell a "SPORT HNDLING"!
My guess whomever filled the tires either did not check the tire pressure or had a faulty gauge.

do ya really think car salespeople are going to take the time the check tire pressures while cars are sitting on the lot waiting for test drives…cold mornings, warm afternoons etc….they leave them over inflated off the truck and should be checked before delivery. Over inflated but within tire manufacturers specs would be hard to believe there is any legal liability on a 10 minute test drive….
I worked at a dealership. (Salesman capacity) Part of the job for the "lot Boys" (girls) was not only clean the cars but to also periodically check for the correct tire pressure and battery conditions. And yes, the insurance that dealerships carry is very specific about the coverage. You can contact any insurance carrier that will cover dealerships and inquire about this subject! Please report should you do so what you find out!
Chick19 is a little accurate, but it really depends on who the auto manufacture is and who they use to ship the vehicles. Most are exactly left with what they rolled off the assembly line which is the doorjam recommended tire pressure.

It's not perse the salesman responsibility at most dealerships.
