Just switch to tubeless rim tape. Even if you are using tubes it’s just a better product that will stay in place and hold up better.
Also, the rip near the valve probably isn’t from the rim tap moving but possibly over tightening the nut or using a presta valve in a rim drilled for Schrader. Also if you don’t have enough pressure then the tube may slide around causing this issue.

It looks like the hole in the rim is for a Schrader valve, and the tube has a Presta valve, which is more narrow. You can replace with a Schrader tube, or if you want to use a Presta valve, you can get a little rubber grommet that reduces the hole size.

Get new rim tape. The new one will have a fitting hole, preventing it from slipping. Or you could go for an adhesive one, for that obviously won’t slip. Also run your tires on correct pressure, this will increase the friction between rim and tape.
Tip for mounting the tape: put a 6mm allen wrench in the holes of tape and rim so it doesn’t slide.

On Thanksgiving afternoon, I did some maintainence on the right front wheel on my recumbent trike. New rim strip, new Schwalbe SV 6 tube, tire was almost new (less than 5 months).
Five days later (mid-day on Monday), as I’m riding along a trail, the same wheel emits a ‘pop’, followed by the sound of a flat tire rolling. Had to push the trike home about 1.5 miles. When I took it all apart, I found the rim strip had shifted, and the new tube had failed right where the base of the valve stem is bonded to the tube. The rim strip may have been the cause of the tube failure, or the rim strip may have shifted during the 1.5 mile effort to get it home, I cannot tell which happened first.
When I first installed this tube, I had a bit of an issue with the nut that retains the valve stem to the rim. Screwing that nut down before final inflation, caused the tube to not inflate fully in the area immediately behind the valve stem. Unscrewing that nut, allows the tube to inflate more normally, then move the nut down to the rim after inflation.
Between the time the new rim strip and tube were installed, until yesterday’s failure, I rode it between 20-25 miles. Everything seemed normal. I should also mention that the past 4 mornings here, have been below 0c, then warming up to between 15c-20c. Not sure if the cold may be part of this story.
Would appreciate any ideas before I replace the tube. I have one more Schwalbe and one more Duro tubes in the box.

that cut by the valve is caused most likely by your tire being underinflated not the rim strip. basically if you don’t inflate your tire properly when you brake the whole tire will slide on the rim and cause your tube (and the rim strip) to shift inside the tire thus causing the cut you see. Also wouldn’t hurt to make sure there isn’t a sharp burr around the valve hole on the tire as that could also cause the hole in the tube.
make sure you have a decent pump WITH a gauge and check your tire pressure at least weekly.
edit: also looks like you might be using a presta valve in a Schrader drilled rim, you can get a grommet to “adapt” the valve or just use Schrader valve tubes.

I would just cut a square piece of tape and stick it over the hole. Then score it with an X and push the valve through. Now the edges of the tape are between the valve and the rim. Or use rimtape, much better actually.
