Title: Slow Tire Leak
Post by: Mister Tee on December 24, 2012, 04:44:00 PM
More Winter aggravation. My rear tire has a slow leak. Not exactly sure what's leaking, although it was plugged last Summer with no issues. It's lost three pounds in two days.

Any thoughts on how to stop it?  The tire is a fairly new PR2 with hardly any wear on it. I don't want to put some sort of Slime crap or fix a flat because of the TPMS.

It's probably the plug. I'd take the tire off and patch it. Plugs usually work pretty good, but sometimes a patch is the way to go.

It seems that cold weather can affect the air tightness of a plug. Also, sometimes when the tire tread wears the plug loses some of its seal. Best thing is to install an internal patch if that is cost effective. I have successfully stuck in new plug a few times but it has not always worked.

Spray some Windex or soapy mixture on the tire til it bubbles up and you'll find your leak.

Once a tire has been holed, the carcass can channel leaks all around the puncture that a plug can't seal. A big inside patch may do it, or junk the tire.

+1.   You may have a problem finding shop that will install inside patch in motorcycle tire for you.

A new tire is the best way to go, Hate to have a plug or patch give out while your on the road.

Check the valve stem. After having a new tire mounted on my Vulcan I had the same problem and it was a loose valve stem. I tightened it and it has been good since.

The safest way to plug a punctured tire is with a combination plug/patch. But this obviously involves removing the tire from the rim and reinstallation on the rim.
Most tire stores use patch/plug these days to fix car tire flats.

Patches are OK if the hole is small and near the center of the tire.  I have run into problems trying to use a patch on car tire punctures that were too close to the sidewall.  In one case, the constant flexing of the sidewall caused the patch edges to curl up and finally the whole patch came loose, causing tire to leak again.

The only practical way to fix a tire punctured very close to the sidewall is with a plug.  Do not attempt to plug a tire punctured on the sidewall itself, except in an emergency and then be very careful,  limit your speed,  and replace the tire at first opportunity.

I have the same problem and it is my plug.  LOTS of tread left so I am at a cross roads.  If I had a tire machine then it would be a lot easier.  I would hate to pay for a patch and then it leak a short time later.  I tried to replug it but it still leaks from the plug (soap test).  I am just adding air before riding until I figure it out.

Yeah I run plugs all the time but once a tire is a hassle its gotta' go!  Just for convenience. 

I mean if you're taking a rim/tire off anyway why patch a POS when you can simply replace it (http://i80.photobucket.com/albums/j180/stevewfl/bigthumb.gif)

Yeah, that's what I'm thinking.  This is actually a replacement tire that I had ordered for one that was unrepairably damaged by a large metal object putting a quarter inch gash in the tread.  I couldn't even get a plug to hold for the trip home.  Plus the tire was already mounted twice - the zoo animals that mounted it, put it on backwards initially.
