2021 F150 Tremor wheel specs - 18x7.5 ET 34

[Yeti]

Someone from another forum confirmed the OE wheels are 18x7.5 ET 34. I know I have at least 2 months to find the replacement wheels and 35s but this gives me something else to second guess during that time.

So question for you. How will you adjust the computer for larger tire size so your gas mileage will calculate correctly? I run 33's now on my 2020 F150 and its off.. Ford said they could not adjust for me.

I used Forscan to adjust my 2020 when I put on 35’s. It was quite easy. F150forum.com is the best place to look up that.

Find another dealer. with a planned 2" lift and larger tires, I'll ask them to recalibrate all of my instrumentation and sensors

I'm throwing on Maxxis Razr MT's in either LT285/75R18 or LT295/70R18. Looks like I'm lucking out as both are approved for 7.5 rim width.

so the wheels at 34 offset, thats how they are getting the wider track, i think regular stock wheels are 44 offset

Where do you find 7.5" - I found one reference at a third party reseller said 8.5". ford is tight lipped and find zero specs online

By looking at the wheel on the truck.

Can anyone tell me what the stock general grabber 18” SL rated tire pressure stamped on the name plate?
Thanks
edit, found out from a tremor owner - door says 38 but they ran 37 front / 36 rear
