Why my dealer set tire pressure to 32 Psi?

[kaboose]

Why did my dealer set the tire pressure to 32 Psi when it clearly says 35 Psi on the door jams. Do you guys set the pressure to what it says on door jams or keep it little lower?

[Takumi616]

People make mistakes or just careless :loco.... I set mine 34 Psi all around.

Are you sure your gauge is accurate?

Well i went for a oil change and the guy clearly wrote 32 Psi on the inspection report so that confirms my gauge is correct.

check the tires after driving around for a bit, after they warm up, should increase a few psi. plus depending on tire size, psi doesnt have to be exact, just better fuel mileage handling etc.

Industry standard is 32psi and that's what most shops use. This is not correct however but a good base presure to start from.

Just top it up and check it at least once a month especially now that the temps are swinging up and down.

Just curious, but what is the correct PSI to run on 195/55/16's?

I usually set mine to 32, would it be adviseable to run them at 34 instead?

[Sonic31]

oops I mean 205/55/16 my B

Look for the tire pressure sticker just at the bottom of the driver's door. The pressure will be listed there.

[standsideways]

Keep in mind kids the door sticker is for your OEM tire and is also a COLD pressure suggestion.

There is no industry standard with tire pressures, because trucks are NEVER 32psi vans NEVER 32psi
Sports cars NEVER 32psi
4wd not usually 32psi

32 psi is a good starting point on a passenger tire in a small or midsized sedan, where youd like comfort to be #1

I'm assuming you have a new generation 3 as the previous generation ran at 32psi. The service person was probably just not thinking straight.

That happened to me once too and I got the same answer from the dealer and I was told that if I want specific tire pressure I should tell them before the service. I always put it to 35 psi as this is what door jamb says and I feel that car drivers better.

so elmo = kaboose?

I can merge them if that is the case.

Hey I found my kaboose password now. So no worries :) Thx

Thx for replying everyone. Yes i have new gen mazda3. I have OEM tires. So that means i should atleast increase my tire pressure to 34Psi.

[insomniak]

YES cold pressure 34psi, although going 32psi will not kill your mileage...
i'd still increase it to 34 tho if your on OEM's if your concerned about it...

not an industry standard as standsideways said, but it is the most common passenger car tire pressure
most people in the garage are under pressure to get the job done fast and never check the door jamb sticker for the correct tire pressure spec

it is indeed a concern!

the tire pressure must be run at 35psi for safety reasons... low tire pressures increases tire wear, (obviously) hurts gas mileage, but ultimately increases tire heat which increases the likelihood of a blowout! 32psi from 35psi isn't a big difference and more than likely won't hurt anything in the near term, but it's still not good to do this... mazda chose the 35psi pressure for ride quality, handling, fuel economy, and LOAD reasons... radial tires require a certain pressure for sidewall strength, which also is responsible for carrying the load of the vehicle... when running low pressures, the sidewall could get damaged and the broken radial cords compromises safety/handling of the car (a bubble on the sidewall is indication of this)

in our shop we use 35 for winter time
