You may remember that I ran for several miles last year on a flat front MPA. :eek:4: At the time I didn't think I'd damaged the front wheel although the tire was ruined. Now I wonder...

I started slowly losing front tire pressure a couple of weeks ago. Now its gotten bad. I tested with soapy water tonight and there is a large section of the right side rim with lots of leaks - may 6 rim leaks in about 1/3 of the circumference of the tire.

BTW - a few months ago I had a rim leak on this same wheel. Remounted the tire and tried to make sure there were no burs on the rim. No leaks after that until now.

So - I think I may be looking at a new front tire. What's your thought on this?

There are places you can get wheels repaired.

When you break the bead down on the rim look for "buggers" on the tire bead it self. It could have been damaged when installed. I think if the rim itself was bad the leak wouldn't come and go,,,,,,:shrug:

And would that mean a new tire or can that be cleaned up?

If the tire bead is broken the tire is bad and will leak air. If the rim seat is nasty, that can be cleaned up to a point.. If there are gouges in the rim in the seat area the rim is shot, but may can be repaired ( if you can find someone that does that ) There could even be something in the bead seat area that is causing a leak ( goes with nasty bead seat on the rim )

Sometimes aluminum wheels will begin to oxidize because of various lubricants used to mount the tire. It happened to me and I had a section several inches long similar to what you described that was leaking badly. I remove the tire and thoroughly cleaned the inside of the rim where the tire mounts. Worked fine afterwards. A tire shop that I deal with told me they run across that problem frequently with aluminum rims. May not be your problem but worth checking out.

In the mean time, take out a big hammer and hit the tire tread a few times all around the circumference of the leaking area. Sometimes it will seat the tire and the leak will be gone.

Cleaned the bead area up today. It was really nasty - surprisingly so. :22yikes: I cleaned it with a wire brush, sanded it, spray painted it with clear, and used bead sealer. No more leak so far. ;)

Well that front wheel is not cheap .

I would do one of two things, I would sign up on all the motorcycle salvage sites and buy a new front rim , or have that one re manufactured .

Something is not right, sure dirty built up rubber and corrosion can make them leak, but repeat leaks are very suspect.

Road damage can warp a rim just a bit, so that in a lean or under some conditions the bead can and will leak.

But that is me, I am very particular with my wheels and tires.
