GRAND PITSTOP 20 Pcs Tubeless Tire Puncture Repair Kit with Mushroom Plug for Tyre Punctures and Flats on Cars, Motorcycles, ATV, Trucks & Tractors (15 Mushroom Plugs)

I got this kit several months ago for my Indian Chieftain, and today was the first time I had to use the product. I've had motorcycles for almost 40 years and had a puncture only once in the all that time -- needing to use one of those old plug kits with glue and CO2 canisters. I bought this kit because it looked durable, the concept (mushroom plug) looked promising and of course... the positive reviews. So today... I was in this little town 70 miles from home for a rest stop and when I left, I was immediately notified by the bike computer that the pressure was less than 19 psi :( I rode back to the gas station, checked the rear tire and sure enough -- there was a small hole but no nail or screw. I got the kit out and the first thing I noticed is the instructions have these very small pictures that accompany the text, crammed into one page -- which are way too small to see what is being discussed. The text is fine but you need good pictures to properly understand the process of the repair. This was one big mistake I made -- I should have reviewed the instructions (and the video) to understand how to use the kit before I actually needed (instead of buying and tossing into the side bag). It's also a mistake the vendor needs to correct -- put larger pictures in the instructions and it will be a lot easier to implement the repair. After 10 mins of fiddling, I finally figured out what to do and the kit worked exactly as I hoped and expected. There were no issues using the silicone plugs and they worked like a champ! I pumped the tire up to 41 psi and watched to ensure it didn't slowly leak (it didn't), then rode home -- the 70+ miles and monitoring the tire pressure screen on the bike -- the tire pressure didn't drop below the 41 psi I put into the tire -- awesome! I think the kit is great, the tools are good quality and the process was easy (once you figure it out). They just need to correct the instructions. And if you do purchase it, make sure you know how to use it before you need it.

Working great so far. Used it to repair a hole from a cotter pin in my ebike tire (antic E-Bike by one wheel) I'll update my review if there are any issues. I'm happy with the kit though. 20psi

I think it is a quality product, but it did not work for me. I ended up buying two new tires for my ATV. Air still leaked around the plug. I had the same issue with the old style plugs, and I was hoping this would work. I did keep the product for future use, as I think it is a good design.

This is the 4th or 5th time I've used this thing. First time was an old trailer tire. Do not run the reamer all the way through. It's stepped and you only need the smaller bit to go into the air chamber. Have put thousands of miles on multiple tires with these in them now. There's no glue, so it's not a "permanent repair". You can pull them apart if you pull too hard. And like I said leave the hole as small as possible. But it definitely works, easily.

Comes as described. So much easier than the traditional plugs. No glue needed. Will be buying more. Takes all the work out of putting a plug in a tire

Back in the mid 1960s I worked in service station for several years when attending college. The proprietor had a device that was similar to this one in that there was an inserting tool and the plugs had a serious circular arrow head on the end of the rubber shaft. He would clean the hole well, put the plug in the insertion device with some sort of liquid on it that acted as a lubricant and ultimately a sealant. The end of the insertion tool was positioned over the hole in the tire and with arm and hand muscle only was manually inserted in the tire by pressing on the handle of the insertion device which drove the plug into the tire. When he withdrew the insertion tool the rubber plug stayed in the tire. He then pulled on the plug to be sure the inside of the head of the plug was tight with the inside surface of the tire. He then cut off the stem of the rubber plug so it was perfectly flush with the outer surface of the tire. The tire was fixed. Didn’t have to remove the wheel from the car and IT DIDN’T LEAK. The whole process took less than five minutes. So, having seen the Gran Pitstop product I thought it would be similar. NOT SO. THe plugs are small and greasy. The insertion method doesn’t work. And in the video I watched, the person using the Gran Pitstop product was happy because the plug he installed only lost 1 pound of air per hour after he was done. Apparently this is not a final tire leak solution. When I tried it, I could not get the rubber plug to push through the insertion device and they usually ripped as well. This is a fairly complex system to accomplish nothing. It doesn’t work. DON’T WASTE YOUR MONEY AS I DID.

Had a small piece of wire in a tire on a Mercedes R class, this uses run-flat tires, as there is no room for a spare, thought I would try this kit, then have it along with me just in case. Kit seeps well enough made for the price point, unlike others, with the kit in hand, the instructions made perfect sense, Pulled the wire, probed and reamed the hole, installed a plug in the gun, put the tip on the probe,seemed like a good idea to use the probe to start the tip into the tire. While I could get the probe through the tread, I was unable to force the tip into the tread. Although I'm nudging 70, I'm not that small of a guy, was a diesel mechanic for years, still active, and can still throw cement bags around.. I tried with air in the tire, tried lubricants, tried to beat it through with a dead blow hammer - this was off of the car, so was able to position to my best advantage. No joy, I gave up, and took it over to Discount tire - in my area, they repair for free. Couple of things - would probably work great on a motorcycle tire. I know the run-flat tires have more structure in the sidewalls, not sure in the tread area, but when reaming the hole, I was feeling a lot of steel in the tread. Also, I reamed only to the first step on the reamer, about 3/16", could not really see reaming a small hole any further - why make a small hole bigger, just to fill it up - the plugs are only about 5/16", and are of pretty soft rubber. This may work for you, just did not for the application I purchased it for, I will return.

I’ve used rope style for over 40 years but this time a3/8” bolt the rope didn’t seal yet one of these did the trick
