Tire dealers over inflating tires

[loneryder]

Can anyone shed light on why tire dealers inflate tires to their max pressure? Had 4 new tires tires mounted today and my SUV was wandering all over the road. I knew there was too much air in them. My inflation monitor showed 50# in each before they got warm. The side of the tire states max inflation 50#. Mercedes says to run 32 front and rear for normal loads. I run 35 all around and have all my tires wear evenly and the ride and handling is nice.
Even Costco inflates your tires to 50# when they rotate them. I've argued with them.

I had to let out 15# out of each tire after they cooled down when I got home.

Please don't anyone be mad when I say this: they probably don't pay enough for the person doing the work to care. I have worked with so many people who take no pride in their work and just point to a seemingly low pay for them to just do the absolute bare minimum or less to get by.

Last time I got new tyres the guy said to leave them at 40psi for a couple of days to make sure the bead seats correctly and then I can decrease them to 20psi.
It might be worth adding I have 20 year old paint chipped steelies.

Someone took care to put exactly 50 in each tire.

Easier for most people to let air out than put air in.

You don’t know that the gauge didn’t max out at 50.

I always check new tire pressure the next morning cold. I’ve always had to adjust….letting air out. But I still like running my tires 3-4 lbs higher than the door jam recommended pressure.

I normally use Discount tire, and they always set it to the placard pressue. (38psi in my cmax)
when i used a local indie shop, they did the same, as did the local Ford Dealer when i had them put tires on my Neon.

the one time I went to the Local Good year shop, ( a month before going away to college) I didn't get the car back for 2-3 months, as they crashed it into their building, and had to repair it for me. ( shop of my choice, with Unibody "frame damage"... ran it into the brick pillar between bays, head on with enough force to crack the Rad...) So i don't really recall what they set the tires at...

if you're wondering HOW they did that... the car in question had previously belonged to my Grandfather, whose right leg had been amputated, so it had a second accelerator installed to the LEFT of the brake. kid must have thought it was a clutch...on my Automatic car... only thing i can think of..

that second accelerator came in handy when I broke my right leg. I told the Doc about the car, and he said he was fine with me driving, since i had a properly equipped car....
after the accident, while it was in the body shop, they went ahead and removed that second pedal. ( they were the ones who installed it for Grandpa in the first place)

They probably have an automated inflator that was set to 50 for a previous job and they weren't attentive enough to reset it or bleed down.

I mount my own tires and send mine to 45-50 to seat beads, but bleed them down before hitting the street. I'd never do it for a customer car though.

In winter when I worked at a tire shop I put in an extra four pounds to account for the room temperature shop air "shrinking" at outside temps.

20 PSI?? That sounds incredibly low. What car is this for?

A friend had her older Highlander serviced at dealer, she gave me a ride and I noticed it drove 'stiff', all tires were at 40#, reduced pressure and ride was normal and pleasant. I don't get it why they do this.

Easy fix, I don't really care. They never set them where I prefer anyway...so first thing I do is set them up the following morning cold.
I have a bigger issue with over torqued wheel bolts. First thing I do when I get home is crack them all loose and retorque to spec with my calibrated torque wrench. I recheck a couple days later.

I had a flat once 30 years ago and the technician must have thought his impact wrench was a machine gun. I was stomping on that little wrench the car came with (in my suit on the side of a freeway) trying to get all five bolts loose. I eventually got it done...but what a frustrating experience.

Sounds like a ford exploder

New car tires are often overinflated due to shipping and storage practices, and sometimes due to dealer oversight. Tires are inflated to a higher pressure during shipping to prevent flat spots from forming while the vehicle sits stationary. Dealers may fail to deflate the tires to the recommended pressure before delivering the car to the customer.

I have never had this happen in my 20+ years of driving

Every new car i have purchased lately is way over. The next morning I adjust them. I don’t even bother the dealer.

When Discount Tire replaced the tires on the Audi, their system printed out the what psi to adjust the tires, but it was incorrect. The Audi had two sets of values, one for normal load and another for maximum load, the fronts being different from the rears, also. The placard only showed the psi for maximum load, while the owner's manual had both sets. I pointed this out to them and they set the pressure to the values I gave them.

Curious how tires are “shipped already inflated”?
