My car got a nail in the tire and rather than bring it to the garage to have them plug it, I did and took some pics.

This instructable will show you how to patch your car tire.

Step 1: Tools

You'll need:
- Car jack
- Lug wrench (or socket)
- Pliers
- Knife or Knips

- Patch kit
Yup, good instructible. I use this method but the cord I get for plugging is coated in some kind of black gummy crap and they do not recommend rubber cement. These patches only work on tubeless tires, they usually last longer than the tire does too. I have never had them leak or come out.
How much longer do the patches last beyond the life of the tire? Just curious.
<p>Do not! I repeat do not fix any tubeless tyre this way!</p><p>I have been in the tyre industry for 30 year, and write training manuals for tyre companies. this kit shown here in the demonstration in not for highway tyres, and you should never fix any tyre with a plug in the sidewall. there is a reason you take tyres to professionals, that's because the tyre MUST come off of the wheel to be inspected for fractures. sadly just 3 weeks ago a young guy was killed here in our town pumping up a tyre they had fixed themselves....... if.....and only &quot;if&quot; you were stuck out in the bush, yes you could use one of these kits to get you to the closest tyre shop and have it repaired properly. </p><p>Just something to think about....... for every 10 psi of air that you put into a tyre, there is 1 ton per square inch of pressure pushing back against that sidewall...... that means, if you've got your head beside when it go's off. well lets just say it's the same as getting hit in the side of your head with a 5lb sledge hammer = dead.</p>
<p>This is a pretty unreliable way to patch tires, I myself have done it quite a few times to avoid the shop (With mixed results). I highly recommend paying a shop to repair the tire internally, as it will outperform this type of plug. As for the danger involved in inflating a tire see below. </p><p>FYI : </p><p>PSI stands for 'pound per square inch' pretty sure 10 psi = 10 pounds of force per square inch pushing out. Not as you say, 1 ton of force / a 5lb sledge. Pretty unlikely for death to occur unless your working with a Semi truck tire or equivalent.</p><p>Please don't post comments to mislead folks.</p>
If you get a tire repair kit like this do not buy the cheap ones. The first one i bought was about 10 bucks and really poorly made, when i went to plug the tire the metal part broke off and got stuck inside the tire making it worse. Buy a good kit, they can save you in a pinch. You can also plug the tire while it still has air in it, IE if your low tire light comes on and you have a slower leak you can plug it fast and get to the b<br>Next gas station.
Did you take the tyre off the wheel to do it, and how much is it for the kit
Thanks for all the advice. My husband is out of town and my car has a flat so I'm debating whether I should try repairing it on my own or taking it to get <a href="http://www.asaptowingga.com" rel="nofollow">flat tire repair in Atlanta GA</a>. I've never done it before and I don't want anything to go wrong since my life is on the line!
1) Why did you remove the wheel from the car if you are not going to remove the tire from the wheel? Seems unnecessary. 2) The puncture is too close to the side-wall, I am concerned that the flexing there will make the fix not very long-lasting. Is this so? Could you comment? (I am not an expert, the comment above is what I've heard from a tire repair person, in a similar case they recommended to change the tire!)
Hey cpotoso - - I removed the wheel because the nail was on the inner side of the tire, easier access this way. - I believe there is some concern, but these are run flat tires and I am not overly concerned as they have stiffer sidewalls. thanks for asking. -Joe
<p>So you're telling us that run-flat tires don't run flat....&nbsp; good to know.</p>
Thank you for the reply. Good instructable.
.<br /> You could just do what my tight arse friend does - if the tyre stays up - he leaves the nail in.<br /> <br /> If it goes down, he pulls the nail out, glues up the hole a little, glues up the nail a little and then just pokes it back in.....<br />
A tire should never be repaired like this!! Tire repairs should only be done in the crown of the tire, about an inch inside the shoulder. In this case, the nail may have caused unseen damage to the inside of the tire. You may only see the nail head from the out side but the nail may have been rubbing the sidewall from the inside, causing a very dangerous situation" a possible blowout ". A tire that is being repaired, should be removed from the rim, inspected for further damage and repaired with a patch plug...it might cost a bit more but for an extra 20 dollars, it might just save your life!!!!
Tricky spot to plug, it'll probably be OK but plugs aren't a great option, they tend to be used as a stop gap because they can come out etc. Country dependant they can be illegal for road use. In this case it's not a bad idea considering a patch wouldn't take in the corner. Check your air pressure once in a while, sometimes they can still be slow punctures, as long as you keep on top of it it's rarely an issue, usually just a few PSI down over a month. Overall when applicable patching is preferable and pretty simple, just like your bike tyre, the main difference being that a coral rock bit used as a buffer is the norm, it can be roughed and cleaned other ways like liquid buffer, a normal car tyre like a 185-65-15 or something similar can be changed by hand, it's just not as easy without a machine. Once you get to 18" rims and over it tends to be nigh on impossible for most people, 4X4 tyres aren't too bad but Van and MPV tyres tend to reinforced sidewalls which cause difficulty. I may do an 'ible sometime, I've been entertaining the thought...
So it's really against the law in some places to fix your own tires? Considering how well my plugs have worked, this seems more than a little wierd.
Tyre plugs themselves can be unreliable, they're a temporary measure so some places are strict on them being legal, I suspect that you'd be fine using them to get to a place for a repair, patches are inherently more reliable, also if you know how to take the tyre off the rim they're dead easy to fit, just like a bike but with more sanding,...
I keep a schrader valve tool in the car for when this happens (in addition to the plug kit and air pump). They cost about a buck. I unscrew & remove the valve core from the valve so the air is gone in seconds, rather than standing there holding the valve open. The core then goes back in and continue as you indicated. I've never had a plug like this fail, and some of mine have over 50,000 miles on them
Be careful about using plugs on the side of a tire. There are different loads on the side (more flex) which can cause steel separation inside the tire and a blowout.
