Default Excessive right front tire wear?

I have excessive outer wear on the right front tire of my 1931 Slant Window, 2000 miles. Left front has some wear but not too much. This is the first set of tires that I've had on the car since buying it. The original tires did not have much wear but were older and I replaced them when I bought the car.
I feel that I have excessive toe-in on the right front but can one wheel have more toe-in than the other? If I adjust the right tie rod end then I'm just shortening the rod?? Correct?? And then will have to reset my toe-in and I will end up with everything the same as before.
I measured my toe-in and I am toed-out 1/8th inch. 2000 miles ago my toe-in was set properly.
What do you all think?

Perhaps you hit something and bent a component?

I would say you have two things going on. With both front tires wearing on the outside, you need to check how much toe-in you have. The excessive wear on the RF might be caused by the right front brake adjustment being tight and that wheel doing a larger proportion of the braking.

I was also wearing out only one front tire. It turns out the camber was out due to the axle being bent at some time. I took it to an "old time" alignment shop and they were able to bend the axle to get the correct camber. Now my tires show even wear. It was pretty neat seeing the A on a modern alignment rack.

It seems you have 2 issues. The wear on the outside is likely from camber. These old monsters were made with a lot of camber [ which isn't needed today] and axles can be bent from 80+ years of use. Stand in front of the vehicle with wheels in straight ahead position and take a look. You'll probably see a lot of positive camber, more on the right than left.

Toe is another issue. It should be 1/32-1/16" in. Such a change in such a short period seem like something may have been recent struck and bent.

Yes you can have more toe in on one side than the other, in my case it was a bent left steering arm causing the right front wheel to turn to far scrubbing the tire, take a look at the gap of the tie rod to back plate left side as opposed to the right.

Toe-in is measured from tire to tire, so is always the same on both sides. Caster and camber, not so.

What Jim said.
My toe-in was 7/16”. I noticed it because the center two ribs on both tires had a sharp edge of rubber on the inside of the rib where they had been scrubbing. The wear was even on the center of both tires.

If I get the old 'benders' out [ use to bend quite a few axles, especially Ford I-beams] I prefer to set most old cars like our As to,
Toe-in, 1/32 - 1/16"
camber, 1/4-1/2 left 1/2 right
caster, 4 left 5 right

We have crowned roads and I like to see our A steering wheels return easily and steering effort easier so I like less caster, when able. An old timer front end guy will know what to do.
