Tires way overinflated at delivery

[Carl h]

My Bronco big bend came with the tires inflated to about 45 to 46 lbs. I am going to deflate to proper pressure my question is about the TPMS will I need to reset? Should I go below the pressure I want and let the tpms come on and then raise to proper pressure, or just lower. I do not see any reset instructions in manual. Any ideas

Just lower it to the recommended pressure and after driving for a little bit (10 min) it should reset itself.

Just picked mine up today, tires are at 38-40 when they should be 33. Service departments seem to be careless about these things, my Transit runs 49 front/71 rear and anytime they rotate the tires I have to correct the pressure and reset the TPMS.

Mine were 50 psi all around at delivery.

Same here. I believe they over-inflate to improve stability during shipping (less play when chained down). I asked the dealer to set them at recommended pressures when they in-processed the vehicle, said they would but did not. I did it myself and didn’t need to reset the TPMS or anything, just took a couple drives and a couple iterations of de-inflation and inflation to get them to the right spot.

Because of earlier thread here I checked mine the day I picked it up and dropped them from 42 to the specified 33#.

Exactly correct, tires over-inflated prior to rail shipment to reduce load shifting during transit. Tires supposed to beset to correct PSI prior to delivery... a lot of dealers don’t catch it.

My vehicle was a mannequin and when we purchased the tires were overinflated as well.

Mine 38 and 39 upon delivery, but the Falkens say max psi is 51. I haven't reduced it yet but will eventually.

Something to keep in mind regarding tire pressure is that 33 is just the recommendation from Ford, not the maximum. The tire manufacturer sets the maximum.
I posted this to another thread but it’s relevant here:

As far as the Ford recommended tire pressure (33psi, IIRC), keep in mind that this number is obtained through testing in a wide variety of scenarios: high speed, low speed, cornering, heavy load, light load, rain, dry, etc. Fords recommendation is a “jack of all trades” number, in that it does well in all conditions, but exceeds in none.

If you wish to reduce your tire pressure, a small handheld gauge would be best. I’m not sure how often the TPMS updates the readings. There is no reason to “reset” anything.

I'll admit it's an easy adjustment, I just wish it had been done already like they told me they would. I did it cold, turned the truck on and scrolled to the tire pressure screen, and then went around to each tire manually deflating. From the time I stopped on each tire, it'd take about a minute or two to reflect on the screen that I was monitoring through the windows, so I just kind of went from tire to tire around a couple times. From what it showed after, those pressures stayed within about 2 PSI cold measured a few times after a week of trips, so was pretty accurate right off the bat.

RF = 44, LF = 46, RR = 46, LR = 45; slightly overinflated according to my FordPass

I better let some nitrogen out.

When I picked up my Badlands and the sales guy was setting up Ford Pass, I noticed the tire air pressures were in the 40's, I had the service manager at the dealer correct the air pressure before I drove off.
