GRAND PITSTOP 36 Pcs Tubeless Tire Puncture Repair Kit with Mushroom Plug for Tyre Punctures and Flats on Cars, Motorcycles, ATV, Trucks & Tractors (30 Mushroom Plugs)

Worked very well to repair a screw puncture. Because it was close to the sidewall(see picture after repair but before trimming) my tyre shop was not confident about patching. Seems to be holding pressure after 2 weeks, I hope it lasts a few months.I needed two attempts. On the first try I did not advance the mushroom top completely into the tyre and also did not unscrew the handle a little before pulling (I.e did not follow instructions)

Easy to use, even for a novice. I have never plugged a tire in my life and was able to fix a flat in under 5 minutes with this. The instructions could have been better if they did more illustrations but they include a scan code that links to their website with a thorough video tutorial. The kit comes with lots of plugs that are pre-lubed (note, dont wipe it off...the lube makes it easy for the plug to slide in thru the tube) and a nice case for everything to be stored in. Keep one of these and a portable air compressor (hand held battery operated work great) in your cars emergency kit and you'll be good.

this is better than to old style they made years ago, the only thing they need to change is the plugs , they need a longer stem on them so the push rod does not bottom out so quick, I found myself having to push it as far as it goes then pulling it out of the tire to help pull the plug out of the tip to seat inside the tire. they need to add another inch to the plug to make it better.

This is an awesome product, only way it would be better, if it came with vulcanizing rubber cement. I have used successfully on big truck and tractor tires., definitely recommend it

This should be the standard plug kit. It took me 60 seconds to plug my first time. I plugged 3 holes in a single tire and they all held.

I purchased the Grand Pitstop Tubeless Tire Puncture Repair kit several months ago. I was planning a cross country trip on my motorcycle. As many of the reviews noted when I was shopping, the instructions suck! Even the video skips the critical step. You insert the plug into the tool as instructions indicate. The plug must be pushed in until it is completely inside the tool. The mushroom end of the plug will look like an umbrella that was caught in the wind. I wasted 3 plugs just trying to figure out what they were talking about in that step. Maybe I am slow. So I figured it out and was on my trip and ended up with a screw in my rear tire out in the middle of nowhere. I followed the instructions and my notes from before. The plugs are greased up with a very slimy grease to allow them to be pressed through the insertion tool into the tire. I got it in and aired up with four 25 gram co2 cartridges. About 24 hours later on my trip my tire pressure monitor came on again. Found that air was leaking around the plug. Installed another one. Then I thought maybe I did something wrong. I stopped where I could get the tire aired up to install yet another plug just to be safe. The next morning the tire was flat. Each time the plug pushed into the tire very easily. It is impossible to pull it out of the tire because of the mushroomed inside the tire, But it does not stay in place with all the grease on it. A little force on it and can be pushed into the tire and start leaking. After three flats because of the at the same punchuer. I used the cord type plug and have not lost a pound of pressure since. I used a 1/2 can of brake clean first to make sure I got all the slimy grease out of the opening prior to installing the cord plug with supplied rubber cement. The mushroom plug does not stay flush with the tire tread, it moves in. I left 1 mm out the tire without pulling on it when I trimmed it. It did not matter. It appears if you run over a small rock it can push the plug into the tire a small amount causing a small leak.

After 60yrs of driving I have found this tire patch kit the easiest ever. Umberella plugs are the only safe quick patches that work. I have lost track of where but there is a source for self vulcanizing pluges that are permanant.

Works well, hasn't leaked so far.
