Problem towing 9500 lbs with 2021 F150 Ecoboost 3.5L hybrid

[Blue Beast]

have to change the tires on my truck ford said that you can tow up to 12700 lbs with this truck but when I tried to tow only 9500 lbs had a severe truck sway at 60 mph seems like the tires that ford puts on there pickup are to light only 3 ply tire ford inform me I was wrong has anyone had the same problem

The powerboost max payload is very low, around 1350 lbs. With a trailer that weight, sway bars and passengers you are defiantly overloading your truck

While I don't have the physical truck yet, putting my VIN in on Ford's Fleet website put my Lariat PB at a payload of 1590 lbs. I've seen some Powerboost trucks with higher payloads as well.

Even with a payload of 1590, a trailer of 9500 lbs with a hitch, 10% tongue weigh a few people and no gear in the bed you are over your payload.

Yeah, of you're looking to max out the trailer weight, the Powerboost is going to limit you. I believe you can get to ~1700# with the XLT if you're light on options. I think most Powerboost trucks are losing about 1-200lbs of payload compared to a 3.5 Ecoboost.

Do you know the model? It sounds like you had "toys" loaded in the rear which tipped it to where the tongue is light. Empty toy haulers have a much higher tongue percentage and should be less prone to sway, but that's a heavy one.... Triple axle?

I agree. The sway is very likely correlated to the way the trailer is loaded. Also triple check the hitch setup. Height, and bar adjustment.

I have a XLT 302a Powerboost with a 157" wheelbase and my payload sticker is 1610 lbs.

Assuming you are talking about a Powerboost hybrid? A limitation of the Powerboost seems to be payload capacity of 1830 lbs before options. Once you add all the heavy options on a loaded truck that number goes way down. Limited powerboost has payload of as low as 1100 lbs (verified by yellow sticker), for example. A 9500 lbs trailer probably has as much as 1200-1300 lbs hitch weight which counts against payload. If you have any passengers or gear in the bed you are over the payload limit which would cause towing stability issues no matter what tires you have. Therefore, the 12,700 towing capacity is not a realistic scenario in my opinion.

Higher load rated tires have stiffer sidewalls and so better able to control the load. E rated tires would be best but they will need more than the standard 35 PSI with the tires provided by the factory.

Sway also indicates that the rear springs are overloaded as well and chaning out the tires will do nothing to fix this. Need to add more springs at the rear axle. People often change out the shocks and this does nothing to help with an overloaded rear axle.

For a 9500 lb load to be towed on a regular basis I would buy a F-250 or F-350 and have a stronger frame, better suspension, and better factory tires.

What kind of WDH are you using? What is the loaded and unloaded height to the top of the wheel well front and rear?

Here's to hoping that he traded it in for a Super Duty and everything is well in the world again.

Have had several travel trailers with empty weights between 3900 and 6000 lbs and found that switching to a heavier duty tire (LT rated tires) made a big difference in the handling of the F150's that I used to tow with. The LT tires made towing a lot more stable. Just as my opinion but it would appear that you are towing way more weight than I would ever attempt with a half ton truck. I got rid of the longest, heaviest travel trailer as I was just not comfortable in towing it, too much of a white knuckle experience for me. I don't care about the 12,700 lb rating, that is a job for a 3/4 ton truck.

Pulls like a dream.

Still, no way is it a 12,000+lb tow truck.
At least not in the shape of a parachute. (RV)

And Ford didn't guarantee that the truck wouldn't run out of Payload way before it runs out of tow capacity.

430HP/570ftlb will PULL just about anything.
But it has to carry it too.

Yep, 250 horsepower will move 12,000 pounds but it won’t stop it! We are spoiled with todays Hemi motors, Coyotes, EcoBoosts, LT series. They all will far out pull what the chassis they are connected to can handle. Braking is what matters when towing at the end of the day.

Would like to see your windows sticker. I have an XLT Powerboost Max tow and I just towed 10800 lb toy hauler from Southern CA to Central Utah. No sway problems, but I did spend literally hours at the scales adjusting my load and hitch until everything was perfect.
