SOLVED: Shimmer / slight lugging in rear when accelerating at low speed?

I remember seeing a write up on the delivery of 2019 Rangers stating that all rangers come from the factory with over inflated tires and the dealers need to set them to the proper pressure during the PDI

As mentioned before, all Ford vehicles come from the factory with tires over-inflated for shipping, with the exception of the Super Duty trucks (they are under-inflated, probably because the suspensions are so stiff to begin with).

ALL dealership PDI (Pre Delivery Inspection) personnel have a checklist of items that are to be looked over, INCLUDING properly adjusting tire pressure. It's a bit concerning that so many dealerships seem to not be following proper PDI requirements. Ford would not be too pleased to hear this, and would send in the regional reps to have discussions with dealership personnel if they were made aware of this situation.

Took delivery last night, tires showing 44PSI. Good to know that I can let some out.

Check the door tag (all cars have them on the driver’s side) for the specific PSI for your truck.

Wow I just checked the ford sync app and my tires are all showing 45+. I wondered why it was so stiff feeling while driving.

 

[rangerdanger]

Tires were at 45 PSI on my test drive, still at 45 PSI after the PDI was supposedly done, and only having reminding them a 3rd time did they air down the tires...

Make sure you check them again when they're cold, they'll most likely be too low then.

I have that feeling too, low speed/slow acceleration has a sort of feeling like power is cutting in and out. I put in 89 octane fuel and now have about 400 miles on it and already the problem is going away. I'll check the tires in a bit and report back. I have a feeling they are over inflated.

You can check the tire pressure on the dash, no need to whip out the tire pressure gauge.

I hadn't connected FordPass yet so I had to go and start the truck to get it connected. 37 PSI cold all around, oof. How accurate have you guys found the built-in pressure sensors to be?

Mine seems very accurate. When i took delivery i had to lower PSI to 30 all around. The tire pressure sensors showed the change within a pound.

Spot on for me.

I picked up my Lariat a week ago and the tires were way over inflated, 45/46 on all 4 tires. Not sure why the dealership isn't checking for this before the deliver to the customer. I lowered mine back to 30 per the manual.

The Driver Door Tag shows all 4 tires should be at 30. Factor sets a 45/46 as a default.

The Driver Door Tag shows all 4 tires should be at 35. Factor sets a 45/46 as a default.

Mine states 30 PSI and that's what the dealer had them set at during their PDI.
