I predict you won't have the problem. Most of the valve creep comes not from riding underinflated tires but from wheeling the bike when the tires are uninflated. You can get a ton of creep rolling it a short distance. Try not to think about the problem.

Just epoxy the tire to the rim. Never have to worry about it again.

Its funny how we all get restless this time of year. Its funny how we'll discuss anything, and even the most rudimentary topics become a hotbed of discussion. At least we're all amicable!
For what its worth, I won't even add air to a customer's schrader-tubed tires if its gotten crooked. I'll always deflate all the way, break the bead, and rotate the valve into the correct position. I'm pretty OCD about that sort of thing. Hey, I would notice it if an LBS mechanic did that to my bike, so why would I taint my reputation. If its not right, it doesn't leave the shop (customer idiosyncrasy's notwithstanding)!

Totally forgot that in the early 70's at least there were Rim Locks for motorcycle tires- a hard rubber oval piece that caught the beads on both sides, held in position with a bolt through a hole that looked a bit like a schrader valve.
Not sure how the mass was accounted for, maybe near opposite the valve? Balanced later? If at all, these were for off road bikes, where low inflation could help, like sand dunes.

Schwalbe sells fully threaded Schraeder tubes w/a retaining ring like on Presta tubes: https://www.schwalbetires.com/bike_tires/tubes/finder. Those hold pretty well.

The Conti tan sidewalls seem somewhat fragile. The squeeze and drag will fuzz them up.
I can't tell for sure if it structurally damages the tires, but it sure looks ugly.
Oh, plus a tight fitting tire may take more work than other brands to force them to slip.

yeah I have some tires that don't rotate on the rims, after both beads are on. so I'm sure to get everything lined up nice before getting the 2nd bead on. guess that's a good thing tho

In my experience valve creep happens mostly by low pressure, but one of my friends had this problem on his front wheel and the only way to fix it was replacing the rim. It always happened after some heavy braking downhill with a loaded touring bike, not on flat ground with the same unloaded bike. We tried more pressure, changing the tire, degreasing the rim, etc., but the valve kept creeping to a 45º angle.
