Losing air at rim
« on: June 12, 2017, 03:30:20 pm »
This isn't a C14, it's a 1994 Virago XV1100, but it has a tubeless alloy wheel the same as my C14 so thought I'd ask it here.  Admins, please feel free to move it where you want, if needed.

I have a 1994 Virago XV1100.  My wife rides it, and mentioned the tire went flat on her just as she was just getting to work last week, she was able to keep it upright, and rode it the last 1/4mi to the parking lot to get it off the side of the road.  I trailered it home, dropped off a car for her, and went about trying to find the leak so we could plug it.

I grabbed a bucket of hot water, tossed in a bunch of dish soap, and soaked the tire down, I got no bubbles.  Then while we were both sitting there scratching our heads, we noticed what almost looked like shaving foam, oozing out of the bead.  I wiped it off, soaked some more dish soap on the tire, same thing. 

Is this indicative of a bad tire, bad rim? or do I just need to break down the tire, clean the rim and re-seat?  do you think the last 1/4-1/2mi roll to have damaged the tire?

Thanks for the help.

  You probably have debris and a little corrosion built up on the rim that needs to be cleaned off.  A little sand paper or a Dremmel Tool should clean it up.

definitely worth a try to do that.  It happened on my sidecar wheel.  taking it off and re-seating it worked like a charm.

Coin toss time..
If it was totaly flat, like rim flat on the sidwall of the tire, and zero inflation or air, and also bead unseated during this last stretch, you need to ask yourself if its worth risking that on your wife.. side wall damage is invisible by most means, from looking at it.. edge of rim running a few hundred yards, or a 1/4 mile, can easily destroy the internal belting and structure of a tire...

Its a call you need to make, depending on the tires age, and risk factor.
If the tire is 5 years old, or more.. ditch it, and buy a new one, your wife is worth more than that.

If its a very new tire, peel t off, and look inside, to see if belts, or cords have been compromised... any visible radial line of demarcation will be seen, and if its present.. ditch it..
Scrub the rim with a wire wheel chucked in a drill, and clean it spotless, then follow up with a scotchbrite pad, and brake cleaner... clean tyhe tire bead (if you are re using it) with brake cleaner and a scotchbrite pad also... re mount using tire lube, or isopropal alcohol, or whatever, and keep an eye on it.. change out the valve stem poppet also, or install a new one, save yourself future headaches..

Ride safe

Brand new shinko 777 white wall so not an expensive tire by any means.

I'll probably break it down and check it over this weekend.  My brother had a local shop put the tire on before he sold us the bike.  I do my own tires now so I know it was done right.

Considering it's a $60 tire probably just worth replacing it. 

I just want to make sure the rim isn't pitted and junk.

broke it down, found it had a tube in it, tube had a flat, was pushing air out of the bead.

I cleaned the bead, I'm going to get a valve stem and a tube.  I'll try the valve stem and no tube first, if it holds air, I'm good, if it doesn't, I'll toss in the tube and away we go.
