Whee!
For the past year or so I've been using a No-Mar tire changer at home. With the right technique, tire changing has never been easier and it has already paid for itself.

Key words there: "right technique". The No-Mar lube is a very slippery vegetable based compound that should dry up over time, but not when you use too much. Too much and it can cause your tire to slip on the rim, which then causes an imbalance. So, for those of you who change tires on your own, be very careful and use only the bare minimum required to get the tire on.

Here is a great guide I found: https://www.nittotire.com/media/188014/TechBulletin_NTSD_12-015-Rev-3.pdf

Do NOT apply the lube to the bead locking area. Only to the drop center ramp and to the narrow lip of the tire. Hope this helps someone!

Titanium rim locks next time?

yep, I've seen the yellow move from alignment with valve stem.

on some marchesinis I have the bead rim is very rough. sandpaper like. to help retention I bet.
 
There's no reason to apply lube to the wheel. Lube up the tire bead.

The tire moving a few inches won't cause a large enough imbalance to matter. My race tires occasionally move that far w no problems.

Good tires are generally very well balanced by themselves. Balancing usually fixes wheel imbalance. That's y the weights mostly go in the same spot every time.
 
The tutorial video on the No-Mar website instructs you to use waaaay to much of their lube.

My tire managed to rotate a whole 180 degrees from where I put it :wtf

I didn't check balance after though.... so maybe it was still fine.
 
I lube like its a honeymoon. I'll have to check my tires now.

I just wanted to state, Tube Tires can rip the stem apart if the tire moves around the rim. and alot of dirtbikers run Low air pressure that requires the old fassion RimLock clamping the rubber tire bead against the rim. And yeah, this aint really news, haha. I just wanted tobe "clearly" understood.
I think most dirtbikers use the dry Baby powder for mounting tires because its cheap and this dry lube works good. But i love to exsperiment, find different techneques. since im a "dirt biker", im wondering what some others use for mounting (tire) Lubracation?
I have been thinking of trying something that will change from a "Lubracant" into a "glue". Something that will help to mount a tire on the rim and after its all mounted, the Lub will become something that actually helps hold tire.
Kinda like using Hair spray while installing the rubber handlebar grips. BUT it needs to be CHEAP!
I think Hair Spray drys too fast for use on tires.
I was thinking of sugerwater too, but thats probly not a good Lube...so, any ideas?
 
I think that PDF is car-centric and not moto-centric. Try mounting a set of Angel GTs or any other heavy touring tire on a wheel with very little drop without lubing the bead. It ain't going to happen.
 
I use Windex on my tires. It slippery initially but dries and actually gets kinda sticky....my tires never slip:)

you can probably mount Pr4 without lube. they practically slip on

The key is lube in the right spot. That is, only along the lip of the rim, and a little on the ramp of the drop center. NONE on the bead seat area.

The baby powder on the tube isn't meant for mounting lubrication, it's to reduce the friction between the tire and tube. I'm not sure how effective it really is, probably doesn't last long.

For mounting a dirt bike tire by hand, I literally use whatever liquid is close by (windex, soapy water, straight water, plexus, diluted simple green). I apply it generously to the outside tire bead. All it does is help that last bit of tire slide over the rim when it gets tight without pinching the tube.

I don't think your idea of a 'lubricant' that turns into a 'glue' (like hairspray for grips) would work because as soon as the tire gets wet it will just break down the 'glue' again.

If you have problem with the tire moving, I have found after market rim locks work better than the oe ones. And if you still have a problem you can always drill another hole and run 2 rim locks.
 
Ultra Dawn is cheap, plus when you rinse your hands they will be soft.

Yeag ryan, the Less Lube the better.
And I have been thinking of drilling a hole for a total of 2 RimLocks for the rear. Its seems strange to me,, because mostly I set rear tire air pressure just above 20 PSI. And Other riders claim they use 12 -15 PSI and they dont have problem with their tube stems being ripped.
I think I will Try the "Windex Window cleaner nextime. So thanks to all replyers.
 
Oh, I forgot ta mention, I think the baby poweder also helps *Settle* the inner tube when doing the rutine of air up & releacing air presure before inserting Valve into the valve stem. I did this probly 20 -30 times with the fat (thick) inner tube, even Later spraying liquid soapy water all over the inner tube. the stemm still is at an anggle. so I'm dunn messing with it.
 
I use a spray bottle...put tap water in, squirt some Dawn in it...shake it up and spray it all over the bead all the way around...drys fairly fast...no slipping once inflated that I have ever seen...
