Tire Patch Kits

Was this a patch kit, or a plug kit.

Plug kits are handy and I carry one in our Prius as well. I’m the commuter and if I run into an issue, I have that and a compressor at the ready.

A great tool for a car to have in it.

 

A patch is something you apply to the inside of the tire for a repair.

So it’s a plug kit. But excellent reason to have and use one.

 

If you have a spare you should use it. Plugging a tire will make it fail prematurely because you compromise the belts holding the tire together. So use your spare and get the tire patched.

No it wont happen every time, but why chance destroying a good tire.

 

The PIP didn’t come with a spare.

 

A tire plug should only plug up a hole that's already there, can't compromise anything more. It doesn't make a new hole

 

I always plug my own tires and never had one fail. You should never plug near the sidewall.

 

Or to the outside of an innertube, which is why most of us bicyclers carry a patch kit.

 

I did one plug repair on a stock tire, and another on a snow tire. Each at least 5 years back, with no further problems.

 

I watched a guy at a service station plug a tire for me many years ago. Seemed so simple and he charged me about $5. I've plugged a tire myself 3 times since and all have lasted the life of the tire. They were all near the middle of the treads. The plugs are so good that you can't see them after driving a few miles.

One caution...the really cheap plug kits can break. Small nail holes need to be enlarged in order to get the doubled plug in with the awl-like needle.

I've used two different kinds of plugs, the black rubber ones are a bit thicker and harder to work with than the more common sticky brown, strips that are slightly fuzzy. Either way, once you puncture the little tube of glue, don't expect it to be still be any good next time you reach for it. It's essentially the same rubber glue you can find at any office supply store, if you want to keep some on hand. It does a nice job of lubricating the plug for an easier insertion, but strictly speaking, the glue is not necessary for a permanent repair with the brown strips.

 

I like my blackjack kit in that regard: it has regular and thinner plugs, the tools are heavy duty, and an extra needle is included.

Another thought regarding plug repair:

Both my punctures were quite close to the tread edge. With the first I brought the wheel into the dealership and asked if they could do a proper outside/inside patch repair. They refused, saying it was too close to the edge. They're probably right: the large diameter patch on the inside would have trouble sealing, running into the curve at the corner.

But a plug repair is more compact. I finally replaced that set of tires this fall (when they were off the car, snow tires in use), but that was 5~6 years use out of a tire that "couldn't" be fixed.

There was still plenty of tread on that set, but they were starting to crack a fair bit, nearly 10 years since manufacture date.

 

Done 2 plug repairs. 1st ever was on a vacation and 30 miles from a decent sized town. There was a car repair shop but it was Sunday and no one working. The attached convenience store guy sold be the plug kit and opened the bay door for me to have access to the compressed air. It was kinda scary but it worked and is still going 2 years later.
For my new cars without spares I intend to never use that SLIME stuff unless I intend to discard the tire. They have plug kits and a compressor.

 

A full sized bicycle pump can pressure up a flat automobile tire too. It's a bit of a workout, maybe 5~10 minutes. They're cheap and uncomplicated.

 

Patching the TREAD on the edge IS doable, but, they won't do it because of the liability.
I have patched 3 or 4 of my tired on the tread portion, NOT the side wall. Even though that is
doable with a GOOD patch, it's too risky.
I haven't seen any in a few decades, but we use to have some with a sticky plug attached to a patch.
We'd ream out the hole in the tire, push out tool through, after cleaning up the area inside the tire to patch,
apply the glue and let it dry, then pull the plug through. We'd seat the patch then cut off the excess plug.
The patch with melt into the tire because of the glue, it would become part of the tire.

 

I keep a flat Lock and Lock container with a tire repair kit with me all the time. Started using plugs back in 1977 when I had a Blazer with off road tires. Those tires seem to always be picking up nails and screws. I am not afraid of using plugs and will continue to use them. With the PIP there is not much of a choice. There are now Fix-a-Flat type options that are friendly to TPMS sensors, make sure it is labeled on the can.

 

I remember back before radial tires when plugging a tire was considered OK. Then along came the radial tire and someone said that the plug would not hold up because the steel belts in radial tires would compromise their integrity and all of a sudden a patch on the inside was considered the correct way to make the repair. Everything is about liability anymore.

 

Never had a plug fail on me, or a tire fail because of a plug, Though I have had issues when I cant get the nail out... Have a local gas station that introduced me to fixing the tires with a plug several decades ago... After seeing how easy it was, bought a kit and did them myself. Had gotten several kits over years.

On my Prius, free repair and rotation included with the new tires I bought (was part of special with a rebate).

My wife's car has had plenty of plugs installed the last two years.
