So my New SM tire got a puncture today.

Recommended Posts

Hello guys and girls, I just put some new Michelin pilot powers on my DRZ front and back last month, and with less then 500K on them I found my rear tire was flat today with a cotter pin stright through the middle. I pulled it out most of the way and took a picture of it.

 

I've always heard that when street bike tires get punctured you should never try patching them, I can totaly see why they recommend that for street bikes as they "don't use tubes"...But seeing as this is for a SM which "does use a tube" I was wondering what the general consensus is on just replacing the tube with a new one and if the small hole in the tire should be patched or left alone.

Replace the tube. Patch the tire on the inside. No worries.  A small puncture doesn't do much damage to the tire carcass.

Just replace the tube. I love when sport bike guys come in with nails in their tires (Not because it happened to them, of course) because I get to put them on my bike.

I really think the "don't run a patched tire" logic is a scam by shops to get you to buy a new tire from them, if the patch fails the tire goes soft, inconvenient yes. But it doesn't magically explode and send you off a cliff.

Patch or replace the tube and have no worries. I have had plenty of nails, glass ect. go thru my SM tire and have many carefree miles on the same tires after patch or tube replacement.

Wow thanks for the replys guys, that was within 4 minutes of me posting, talk about great service   :thumbsup:

 

 

Should I use a plug style patch or just a normal style patch?

You may be referring the a patch that is also a plug inserted from the inside.  Yes, I like those but they require the hole in the tire to be made bigger. If the hole is already big a plug-patch is good. But with the small puncture in your tire - no.  No reason to make it bigger.  In fact the inside patch is probably not needed at all but does not hurt to use one.  If you were asking about a standard tire plug, then no.

Yep that's the type I was referring to, the type that is both a "plug molded in with the patch all in one deal". I had the local tire shop instal one of them on my car tires and it worked great, but they did have to make the hole allot bigger so I kind of figured making the hole bigger would be a no-no and you confirmed it. Thanks Noble and to everyone else that replied, I searched Thunpertalk for this particular subject and couldn't fine anything really definitive. So hopefully this topic helps someone out wondering the same thing in the future.

Forest , the plug patches are for patching tubeless tyres and can be used in tubed tyres if you wish . One thing I would look out for is the inside of the tyre where the cotter pin came through . If it caused any deformation of the carcass , it can pinch the tube . That is when a patch on the inside of the tube is a good idea , but as the other guys have said , either fix your tube or replace it as you wish and go ride , greg
