Calling all Alignment PRO's...

Fair enough.
First, no, not everyone's truck is that different. Second, and more seriously, caster angle cannot possibly have anything whatsoever to do with that. It's entirely unrelated. You cannot adjust caster angle to induce nor eliminate pulling left or right, regardless of the actual cause.
I didn't realize you were calling BS on the tire thing. Either way it's difficult for me to let fundamental misinformation stand. Others may read this and be suckered into thinking there may be something--anything--to this tire thing, when in reality it's a bunch of hooey.

Thank you for contacting Toyo Tires USA. There is a phenomenon on some single axle applications that may cause a right pull due to the tread pattern and aggressiveness of the tire itself. This does not occur on every application, however it has been known to occur. If you have this issue and your dealer can not resolve it, it is recommended to return within the Trial Offer period if you chose to remove the tires.
If you need anything further please let us know.
Sincerely,

Now wait a minute...
"On some single axle applications". Because the dissimilar tread patterns don't always track in the same direction. I thought your had 4 of the same Cooper tires?

If you were right, then a grocery cart should be pulling all over the place with a caster angle if zero. And please tell me how you're going to adjust caster 1.5 degrees off from left to right on a solid axle. I didn't intend for people to try to make up weird scenarios where they can imagine effects.

I used to think the same. But caster is adjusted not by shimming the axle, but with caster bushings that fit around the balljoints. This way you can alter the angle of the knuckle against the rest of the axle to adjust caster.

lol yes I have 4 of the same coopers, what they mean by single axle is monobeam, as in solid axle, not independant front suspension. I sent them all of my truck information in the email so they knew exactly what I was asking about. When you submit an email it requires you to fill out a form with what tire you are asking about, what vehicle it is on, etc.

A single axle tire application is installing tires on the front or rear of a vehicle. Technically wouldn't yours be a double axle application with a solid front and rear axle?

Respectfully, I think you are altering the meaning of what they're saying so as to make it support your argument. They say "Single" axle...NOT solid axle. It's commonplace to refer to the front or rear set of wheels on a single axle. Look at the door sticker on any passenger car and you'll see the "Gross Axle Weight Rating" acronym.

I have a simple, specific question. Does the Toyo Open Country M/T tire have any history of causing a slight radial pull to the right when installed on a neutrally aligned solid axle truck like my F250?
This is after I filled out the require form with all of my vehicle information.

OK I emailed them back. I am curious though, what do you propose they DID mean then? A trailer with a single axle? Or if I were to only install two tires on the truck? For what it is worth, my exact question was this:

But if the tires are identical they should track the same. Meaning any off-tracking would be symmetrical between the front and rear axles and they wouldn't cause a pull.

Still his issues could be caused by the lift/oversize tires.

So I removed the stabilizer today. It fully extended in about 3 seconds after I took the stud out of the drag link. I took it for a ride and let the tires warm up fully and it definitely does not pull as bad. It still pulls left, but takes much longer to do so. The only thing it still does that truly concerns me happens when I go around a left hand curve in the road. If I let go of the wheel in the middle of the curve it stays where it is, instead of straightening out and shooting me into the ditch like it should. It does not do this on a right hand curve. I crawled back under the truck and checked the drag link ends and the tie rod ends. All are tight. The tie rod ends rotate a little more freely than I remember, but they have zero lateral play. The track bar bushing and ball joint felt solid. No play at all. I am wondering if I jack the truck up and turn the ignition on if I will see the wheels turn slightly left....maybe I will try that next.
EDIT: I went out and jacked up the front end. Turned on the key and nothing happened. The steering wheel just sat there mocking me, saying "you dummy, of course I'm not going to move on my own". I did however have my wife crank the wheel over back and forth while I looked for issues. I found nothing out of the ordinary. At this point, I am still unsure of the cause. However, I did order a dual stabilizer kit today from PMF.

OK I received a response back from Toyo after asking for clarification on the meaning of "single axle". It was rather short but here is what they said:
"Being a phenomenon it has occurred on different applications, but solid axle’s seem to be the ones that we have heard about."
That seems pretty clear to me.
I love how we have devoted more time to talking about tires that I don't even own than we have talking about my problem with the truck lol.
But that's quite alright as I think we all are here to learn, and I just learned something, so that's good by me.

Do you have a tie rod or pitman arm puller? If so, disconnect each tie rod from the steering knuckle with the truck in the air and see how hard they are to move. Each knuckle should be movable with your hands...if one is much tighter than the other you've found your problem.
