Tire creep
When mounting tires, I always take care that the valve is at a right angle. But lately my front tire is creeping after a few days (probably due to braking forces), risking tube/valve damage. I thought about using some non-slip compound on the bead, like rosin for transmission belt dressing. Any thoughts? TIA

After cleaning everything, hair spray would likely keep things stationary.

The only time I have had my tires creeping was when I was running low pressure in the tire. If I was going to use something on the bead to make my tire stick I would use Tubular Tire Glue. That's just because I still have a few tubes sealed in a mason jar in the beer frig. I would just spread it around the inner lip of my rim and immediately mount the tire.
On second thought... I would spread a very small bead along the inner lip of the rim then let it dry before mounting the tire...
Amazon
Do note that I have had some problems with tire beads on expensive and economical bicycle tires. No matter the make you need to go over your tire beads and scrutinize their sturdiness, thickness, and reinforcement, checking for weak spots. Occasionally the tire rim itself is the cause when it is deformed or spread open. This happens when people ride home on flat tiers.

AHhhhhh... Do I miss the old days when I was a real cyclist and not some old fat geezer poser...
The smell of Tubular Glue... VICTORY!

If you started with the valve vertical pointing at the hub center, then I'd think your issue is too low a pressure in your tube/tire. If the tire itself is rotating around the rim, then that's also probably too low a pressure. Perhaps it's even coming off the bead seat as it shifts position. You could make certain whether it's the tube or the tire by noting the position of the logos and such on the tire with the position of the valve stem hole in the rim.
It's not a uncommon thing. It's particularly a problem for kids bikes with wide tires that even when they are too low a pressure, they are still rideable.

Never had the issue or seen it except for under-inflated tires. I recommend proper inflation and make sure the bead is properly seated as well. The other options are fine to a point but I would actually inflate and seat things first before anything else.

Yeah, but maybe he's 350lbs screaming down a hill at 55 mph with a T intersection at the bottom at 95lbs pressure. That's why I mentioned cleaning the tire bead.

Maybe but that seems less likely than the idea that the tires are under inflated. However yes cleaning the bead could be something to do if everything is properly inflated.

As others have said, low air pressure is the most likely cause.
However, tires have been known to creep, especially fronts as in your case. And, yes, fronts creep because of braking, and while rears rarely do because both brake and acceleration forces are lower, and in opposite directions.
Then easiest way to cure front tire creep is to flip the wheel, and let it creep back home. Of course this won't work with disc brakes. To stop creep, remove the tire and thoroughly clean the rim's bead area with a zero residue solvent, or detergent and water. Likewise use water/detergent on the tire's bead area. Then mount DRY tire and you should be fine.

Thanks all! The tire size is 700x40 and I use 40-50psi, so I don't think its under inflated.
The tubular glue will surely work, but that would be overkill! BITD I had some experience with tubulars and that stuff was very sticky and hard to remove... I'll try cleaning the tire and rim and a bit more pressure, maybe 50-60.

Minimum recommended pressure is 44psi, max 73. Interestingly, for my 26x2.00 MTB, used mostly on gravel roads, min is 40, max 65. I usually use 32-35 in front and it never crept.

Agree low air pressure is the culprit.

700 x 40 tire. What size tube are you using? I agree that if you are using 40 - 50 PSI in the tire, that should be plenty.
Are you checking the pressure often enough? 40 - 50 PSI in a tire that size with a normal butyl tube shouldn't leak down as fast as they do on road bikes with much narrower tires at higher pressures. But they do leak down, just at a slower rate.

I had this issue on a fatbike with sloppy tire/rim contact. My solution, that has worked so far, has been to apply some gummy nordic kick wax to the rim tape, My objective was to fix the tube, and allow the tire to creep.
Edit: My rim tape is Grorilla tape that is adhered to the rim.

Problem solved - just kept tire pressure always over 50psi and it worked OK.

I'm confused. Which tubeless sealant are you using?
