    Rear Tire Slow Leak

    I discovered a very small puncture on my rear tire. It is a very slow leak. I pumped up the tire and checked it the next morning and the tire was definitely flat. A close inspection of the tire revealed the puncture shown in the picture. It is small enough that a coat hanger wire will not penetrate the tire.

    My question is what is the best option for repair? 1. An internal Patch. This would require removal of the rear wheel and taking it to a shop for repair and rebalancing. 2. Plug the tire. However in order to get a plug inserted, I would need to drill a larger hole to allow the plug to be inserted. I have plugged car tires before, including drilling a hole to get the plug to fit, and the repairs have held up well.
    The tire has about 25% life left.

    So what are your thoughts, and pros/cons.

    With 25% left I would be proactive and just replace it now and not worry.

    Plugging is a "bush" fix.

    I would replace the tire and in the future, a patch. I fix ALL my tires with a proper vulcanizing patch. I won't run/ride plugs unless I'm in a bind and I don't want any of my friends to consider plugs as a long term option.

    Camel and others make mushroom patch/plug combinations. They consist of a vulcanizing patch with a plug in its center. You use the attached wire to pull the plug through the puncture from the inside and bond the vulcanizing patch to the inside of the tire. The patch acts like a - patch - and the plug portion seals the puncture from moisture that might enter the carcass/cord area from the outside.

    The questions is, if you dismount the tire to install this is it worth it given the remaining tread life on the tire???

    I'll play the devil's advocate here and disagree. I plug my tires with Nealey tire plugs and wear em out. Never had one fail. That one looks like a prime candidate. Ream it out good and plug it.

    Oh, I should mention I only do this on rear tires...

    I suspect there's little debate about an internal patch being superior but if you're going to pay shop time it wouldn't seem very economical.

    I have no reservations about using plugs for emergency use and typically I leave them alone after inserting and run till done. Have even used them on races tires which is pretty well beyond reasonable boundaries- no other choice at the time. Assumes you know how to do one well. Yes, I've drilled small punctures to get them big enough to plug.

    A lot of the safety issues re plugs are overblow. If you survived the first small puncture, you'll survive the second small leak so why turn into a worry wart over it? Just don't be stupid enough to use plugs where they have no business- multiples, slits, sidewalls, etc unless you going only a mile or 2 to a proper repair at 20 mph...

    Deision Made

    Thanks all for your thoughts. I was anticipating replacing the tires sometime this Summer. Looks like I'll be ahead of schedule. In the mean time, I'll plug the tire. I've done it before and they hold up well. I'm not a speed demon and I don't plan on any long trips till the new tire comes in, so it should not be a safety issue.

    I'll research the forums for any info on tires. If not, I'll open a new thread. Probably go with a mid priced tire.
