  1. Upgraded from 265/60/18 to LT275/65/18 Load E with HDPP wheels

    I picked up my 2021 F150 about a month ago with less than 6k miles on it. It's a 2WD Sport SuperCab w/ Max Tow, 3.73s, and the 5.0L. I bought it as a Ford CPO and when it got delivered, I noticed the stock Hankook Dynapro HT tires were starting to show some cracks on the sidewalls. I hit up...

  2. 10R80 Noise when cold - anyone else with this "issue"?

    I just picked up a used 2021 F150 5.0L and it's currently sitting at 6,240 miles. This 4th 10Rxx I've had, and the 5th 10 speed (I had a 17 Camaro ZL1 auto). I am well aware of the whine at idle and the quirks of this transmission family. I currently have a 2024 Ranger Raptor as well, so I...

  3. Looking for an LT tire recommendation

    I just picked up a used 2021 F150 Supercab 6.5' bed with the max tow package. It also has the sport package with 18" wheels. The truck hasn't even hit 6k miles, but the OEM tires are starting to crack. I'm going to be hauling around a pressure washing skid with tanks in the bed, though when...

  4. Buying another 2021 F150...

    Well, I'm back after less than a year of being without an F150. After being an early adopter of the 14th gen with my prior 2021 F150 Platinum FX4 PB with pretty much every option, I'm buying another 2021 F150. I traded my platinum in on a 2024 Ranger Raptor that I still have. However, I'm...

  5. Can't trade in 2021 F150 with an open recall?

    I am looking at getting a 2024 Ranger Raptor and traded my fully loaded 2021 F150 Platinum Powerboost FX4. My truck only has 8,900 miles on it, is in pristine shape, and I have a title in hand (original owner). There's an open recall (23S65) for the rear axle hub bolt can break and rattle...

  15. Exterior door lock buttons

    Anyone else notice the exterior door lock buttons are stiff and not very user friendly? They seem to take a lot more pressure to lock the truck than I’d expect.

  16. Front door panel / window creaking / rattling (Updated w/ Fix)

    I noticed on my platinum that I have what appears to be some rattling or creaking coming from both front doors. At first I thought it was the door sales, so I put some Krytox on them, but that didn't change anything. Today I pulled off the triangular trim pieces at the front of each door and...

  18. General feedback on 2021+ 10R80 transmission / shift characteristics

    I thought I'd start a thread to see what people thought of the shift characteristics of the 10R80 in the 2021 F150. My general feedback is that at nearly 300 miles, it's considerably improved from my prior 2018 F150 FX4 with the 3.5L and 10R80. Here's where I feel it excels: 1. Cold shift...

  20. Why no HUD?

    With all of the tech in this truck and so much to monitor, why did Ford not install a basic heads up display? My 18 had the flashing red light on the dash for the driver assistance, then they removed that for the 19. It just seems like a great optional item or something to charge a bit more...
