Just wondering if others here powder their tires/tubes.I've done it for 15 years or so,and its now part of my ritual.
This was argued on rec tech and proven beyond any doubt that it could not matter,but I find it easier to mount the tires and remove tubes if I do have a flat.
I have a 2 gallon ketchup jug from a restaurant that I put a bottle of powder in,inflate the tube slightly,drop it in and shake. I also powder a new tire,putting a teaspoon in and working it around,like flowering a cake pan.
Do your friends call you anal? Just razing you, with a smile on my face. Its a great idea, I have had some tire tube combinations stick together with time and wished I had followed your suggestion. It seems like a great idea, not necessary but a good thing to do.
Someone once related a story where they were installing a
bicycle tire that had a tube filled with Slime using talcum powder.
During the process the tube inexplicably burst, covering
them and everything around them in the bicycle shop with
Slime and a nice dusting of talcum.
Paraphrasing from something I posted to Hobbes last year...
Aside from butyl inner tube manufacturers putting talcum
powder INSIDE of tubes during the manfucturing process
where it does serve a purpose, I can honestly say
I've never felt inclined to powder my tubes or any
other part of a bicycle.
Talcum powder definitely served a purpose in
automotive and truck tires in the early days -- before
tubeless tires -- where prolonged heat loads greater than
anything a bicycle tire will experience truly would
vulcanize the outside of butyl rubber inner tubes to the
inside of a tire. Somewhere along the way this necessary
step for automotive tires made its way onto bicycle tires
where it retains its mythical powers.
Again, if anyone finds that it makes mounting tires easier
or does anything else that is beneficial... then just
assume it does and more powder to ya.

I have done this for the last 20 years. The shop owner that got me doing it said it helps prevent pinch flats. No scientific study to back that up but I do get less flats than those around me.

i've done it for a long time too. i never thought that it would help with pinch flats or anything else, except mounting where it helps keep the tube from being twisted

I also think I have less pinch flats, but how can we know. Like I said before, they argued it out on wreck bikes tech and cocncluded that a tube,powdered or not, could not move with the pressures involved,so powdering was a waste of time.
On my cross bike,I have run pressures in the low 20's,dented the rims and gotten leaves in between the bead and the rim,but not pinch flatted. Maybe I'm just lucky.

I don't know if it is a good thing or a bad thing but I've been powdering tubes and the inside of tires for many many years..for me it makes the mounting process nice and tidy....and ...I've never found a down side. So I'm going to keep on, keeping on.
I don't bother powdering a new tube when I put a new tube on, out of the box, at home when I replace tires, but I always pre-powder the tubes I keep as spares on the bike. I think they go in faster and smoother with no pinches in a hurry with powder. I don't think there's any benefit once it's on right and fully inflated. That's important when I get a flat on a ride, it doesn't matter when I've got all afternoon to do it at home.

Have not powdered any innertubes/tires since we used talcum powder on our babies' butts after a diaper change! . . . and that was decades ago!
The powder does make the tube smell a bit nicer when you're checking it up-close for a slow leak / small hole ...
