Are superduty supposed to go at 90 mph with overload stuff SAFETY?

Well I was on I94 so lot people go over 80 mph.

It get my attention. It was company truck with welder stuff. It cruise at 90 mph it not drive straight it like wander due 50 mph wind. I think it 00 or 01 f250 XL.

How they think it safe. Our 01 F250 crew cab aren't safe over 85 mph or you feel shake from wind hit front end and mpg from 11 drop to 5-6 mpg at that speed.


I wish I have got pictures of roof company's 99-01 2 f250 which really really bad shaped it look like it came from Mexican or construction. It worst than that picture. bed are about 9" low on right side than Left side. It ever cruise at 85 mph. No DOT or police stop it. It have 5 ladders on rack and full of roof material in bed.

how you could get to 98 mph? Our F250 just stop 90 mph but will go pass if you lift gas pedal off then push again it go 95 then drop to 90 mph.

keep your foot on the skinny... Mine limits out a 98, just stays there, no rev limiter or anything. It just holds there until you let off the gas. and thats stock programming. I dont have a tuner.

what year is yours?

My 03 excursion V10 will go right up to the 96MPH limiter and its, very, steady and goes straight. Like a train on rails, no problems at all.

Yes a superduty will get up and run with the best of them. Does that mean you should be doing it? Probably not since you yourself said the trucks are showing the wear pretty bad.

So control your speed so you go home at nite...or convince the company that they need to do some maintance. Truck should be stable at all speeds.

Funny,,,that truck went to Nova-Scotia,,,twice,,,Got traded in with 27k on it,,,
My 06' F-350 has almost 47k, on it,,,Never been to Nova-Scotia,,,once,,,,Strange how things are!

Sorry to be a spoiler here but the fact that these trucks can run that fast in a straight line does not mean you should.
If you had to swerve unexpectidely in an emergency manuver you'd be screwed.
8000# trucks with a high center of gravity are not designed to safely run at that speed.

SMLford beat me to it!

NOTHING that heavy can move at that speed on a public roadway safely. Especially something built like a Ford SD! Relatively imprecise recirculating ball steering, high COG, large tires, solid front axle, and tires that aren't made for high speed handling all combine to make a dangerous vehicle at those speeds.

It's a truck, not a Mustang!

Yes. Don't run that fast. When the truck is loaded or if there is a trailer you always should anticipate your turns/lane changes by turning the wheel very slightly until you FEEL the transfer of weight shift to your outside, then after you know the weight has been shifted go ahead and make your turn. Not sure if I explained right but you know what I mean if you pay attention to things.

If I am turning left I always load my right side before completing the turn, opposite for right turns. It's the shifting of weight from neutral to one side or the other that gets things out of shape and once you get 8K or more moving in the wrong direction it's twice as hard to get it settled down without wiggling all over the road. Sudden movements = Bad things.

Along the Southern Border , alot of the Border Patrol vehicles are lifted F250's with big tires. Those guys drive 90-95 all the time on a narrow 2 lane road. I am waiting to come up on one that had a blow out and rolled it.

I've had my SD well over 100mph a few times and its rock steady.(Speed Limter is removed) I was empty and it was a short burst.(little to no wind and traffic) No way I'd run a truck loaded like in the pic that fast especially in a wind. A heavy wind can throw the SDs around a bit especially if its a side wind and your going fast.

SO is it worse he is allegedly doing 90 or you are taking pictures of it while doing at least 80? And yes a Ford Superduty can move safely at 90mph in various situations, if not it would have a speed limiter much less on it.

There is a point where you go over a certain weight, and either the frame is on the axle directly, or there's just way too much weight behind the rear axle, and the rear end sways all over the place. That particular truck either has something wrong with it, or a whole bunch of steel plate in the exact WRONG spot - as in, on the right side of the bed, way behind the rear axle. Or welding rods, or something else. Even though it might not be over the max weight you can carry, it's in the wrong spot. It should be centered, at the front of the bed, and then it would be just fine.

As for cruising at 90, I do it. Often. With a decent load. Is it less safe than 70? Sure. But I don't do it with other traffic around. If a deer jumps out in front of me, I'm going to just go straight into it

That truck, like I said, either has serious weight in the wrong place, a bad set of tires like D's or even C's with too much weight on them (although that pic shows they are not squished), or some other suspension problem like a broken leaf spring pack.
