need help mounting tire

[3Phase]

Yebbut cleaning the rim has been gone over so many times before it'd make it seem like I'm doing the donkey thing if I listed every friggin' detail of every friggin' thing you have to do to mount a tire in someone else's tire thread.

I'm no newby, i did use a scotch brite pad around the inside lip to clean it up.

I'm going to have to find some of that napa stuff.

One of these days, I'm getting a good compressor.

Now, do those balancing beads inside the tire work?

I don't know if the beads work, Motoman uses them but I've never tried them.

I've tried balanced and unbalanced tires and it used to make a difference but the new compounds are so soft the tires never last long enough to tell if balancing did anything useful.

Now I just put the dot at the valve stem, spin the rim a bunch of times to see if it comes up cherries three times in a row or if it's random and don't worry about the tire unless it's obviously messed up and does the Hoochie Coochie, then I just ride it anyway and hope the the heavy spot wears off before it's time to put on an other tire.

What salt?

I've never heard that dish soap was salty.

However, last year I mounted four new tires on my XS750's- my first time.

I put Kenda on one bike and Michelins on the other. I did have to balance them- they were way off.

Everything was great.

Then this spring, I found the front tire on both bikes was low, and I have been putting lot of air in them every time I ride them (~ every 2 weeks).

I tried dish soap spray to find the leak by looking for bubbles, but the leaks are not big enough.

Even before reading this thread, I was expecting the rim corroded under the tire bead over the winter, especially since I cleaned the rims with lacquer thinner and a Scotch Brite.

I did use dish soap and water to set the bead.

So, now I hear that dish soap has salt in it? Or it turns into a salt? Sounds like a likely cause for my issue, especially since I removed any protective coating from the aluminum via the scratch pad.

Where does one go to learn about dish soap and salt? Another thread somewhere?

I was also curious so I read the label on two brands of dish detergent.
One makes no mention of what is in it other than orange scent
The other shows many ingredients and three start with SODIUM.

My front tire has developed a slow leak...I also cleaned up the rim inner edge last time it was mounted.

The Dawn Bottle Label

"Dawn contains enzymes and biodegradable surfactants. Contains no Phosphates"

I'm not up to speed on 'surfactants' yet.

I'm not up to speed on 'surfactants' yet.

Surfactants decrease surface tension in a liquid. For soap they help the water flow onto and into whatever your trying to wash, carrying the soap with it to remove the grease and dirt instead of sitting on top of it making fascinating beads like mercury on a beeswax tablecloth.

The salt is used as a thickener. Dish soap makes nifty bubbles for checking for leaks if you remember to wash it off so it doesn't do the salt-contamination thing.

Scratches and corrosion as well as former tire smears cause tires to bond to the rim poorly. Adding the salt only magnifies the situation. I would suggest that anyone and everyone put ruglyde on the rim and wash the excess off as it will bond the tire to the rim like flexible calk protect the surface of the rim allow it to slide off easier and prevent some leaks depending on the scratch or issue with a tire. I have actually seen it used inside poor quality tubeless lawn tires to seal slow leaks from dry rot like the slime sealer does.

But when all you get is dumb looks when you go looking for ruglyde its time for Dawn.

I did some searching before deciding to post this. I have used WINDEX as a tire lubricant since it isn't as slippery as SOAP, evaporates quickly afterwards. But after reading the above, was wondering about corrosive activity of Ammonia on Aluminum. Aside from SALTS, I do know that HIGH PH Alkalis ARE corrosive to aluminum....another reason why I didn't want to use Dish Soap on my rims! Here's what I found about chemicals and their corrosiveness to aluminum.

Aluminium and chemicals

Thanks to the protective properties of the natural oxide layer, aluminium shows good resistance to many chemicals. However, low or high pH values (less than 4 and more than 9) lead to the oxide layer dissolving and, consequently, rapid corrosion of the aluminium. Inorganic acids and strong alkaline solutions are thus very corrosive for aluminium.

Exceptions to the above are concentrated nitric acid and solutions of ammonia. These do not attack aluminium.

In moderately alkaline water solutions, corrosion can be hindered by using silicates as inhibitors. Such kinds of inhibitors are normally included in dishwasher detergents.

Most inorganic salts are not markedly corrosive for aluminium. Heavy metal salts form an exception here. These can give rise to serious galvanic corrosion due to the reduction of heavy metals (e.g. copper and mercury) on aluminium surfaces.

Aluminium has very good resistance to many organic compounds. Aluminium equipment is used in the production and storage of many chemicals.

I have some PH paper at work, so I can use it to TEST some dish soap. I know BLEACH is like ~11 or so, but not sure how HIGH Dawn is?

Reading info on the Windex site, it says it also has "some" detergents, along with the ammonia-D, solvents, and Alcohol.

Ron, My rear tire looses air every few weeks also. I haven't changed the air valve EVER...I think I did try changing the inner screw in valve portion, but not the entire piece. SO....I'm not sure where mine leak from either....the rim/tire junction, or the schraeder valve assembly? It's been this way thru several tires, Elite II and E-3.
