285 tire on a narrow rim

I have a 285 75 16r that i want to put on a 16X4.5 rim for a rat rod. I know it will wear weird but is it possible at all? My rat rod is super light (1500lbs) and i only plan to run these one the back. If it is possible where can i get them mounted? I know this is a non-jeep question but Jeep guys usually know tires. Thanks

I've run several vehicles with up to 5" difference between the tire and rim. But, going with a tire that's probably 11" wide on a 4.5" rim is really pushing it. I'd be concerned about the tire remaining seated with the set up you're looking at. I think tire shops will think it's risky too - and refuse to mount them.

Might be a tough one. Most large chain tires stores might not want to.
I know one local chain shop didn't want to install my 285x75x16's on 6.5" rims

Tire shop won't install them because the rim is to narrow and--

The COATS tire changer "Bead'slider", probably won't fit between the in stalled beads-

It would look dumb anyway --even to a seagull

Whatever

How did they fit? Do you think they would have fit if the rim was 4.5?

You would have to see the car to get it. The looks aren't as what I'm worried about.

Remaining seated is my main concern. The tire is slightly more than 11 inches. The car will not be corning hard or carrying a lot of weight but it puts out around 400 horse power. I may have to abandon the idea but I hate to because it fits the look of the car

They said they wouldn't do it.
Said they couldn't guarantee that the bead would hold being forced at the wrong angle.
