Grand PitStop Replacement Mushroom Plugs for tubeless Tire Puncture Repair kit - for Cars, Motorcycles- Spare Plugs (15 Plugs)

Every vehicle should have these! Easy to use. Works amazingly. Very durable and the design makes it simple for anyone to use. Stores neatly in carrying case and smaller size fits under your seat. I have used these on motorcycles, trucks and trailers with zero issues! I keep one in my work truck and just bought 6 for Christmas gifts!

I used this kit yesterday on my 2018 Toyota Tundra after discovering a nail in the front left tire, right near the transition to the sidewall. I followed the instructions, pulled the nail, and used the mushroom plug gun to seal the puncture. The process was straightforward and the kit worked exactly as advertised. After refilling the tire to 36 psi, I checked the pressure the next morning and was happy to find no leaks at all. The repair held up perfectly. I’ve seen other users mention needing to lubricate the plugs, but mine came pre-lubricated, which made the job even easier. Another great feature is the vinyl pouch it comes in—it’s compact and keeps all the tools organized. Perfect for storing in your vehicle so it’s ready when you need it. Highly recommend this tool for anyone looking for a quick and effective way to fix tubeless tire punctures. Great value and peace of mind!

Works great! Notice small leaks initially around plug, but quit after properly seated.

Used on my truck 2 days ago. No leaks. I’ll update if there are issues. So far, 100% satisfied. It took less than 5 minutes to fix.

I have been playing with this. so far it works very well... I only wish they had bigger plugs. I have been plugging a 10 ply tire

Used on a set of dual tires for my semi.. works perfectly.. I was skeptical at first but its holding up perfectly.. no air leaks. Easy to use.. I recommend it

Bought these with hopes of finding an easier way to repair a flat. I really liked the simplicity of the plug injector. Just used them today, removed the nail, inserted the plug, filled with air to spec., everything went smooth until I got back in my car 2 hours later. My low tire pressure light was on again. It seems the smoothness of the plugs do not completely seal the puncture, thus it leaks just as if the nail were still there-you’re replacing one object for another which both serve to deflate your tire. Luckily I still had my original tire patch kit and replaced it and it’s good to go. Try your luck with something else, I use Boulder repair kit for all my vehicles, works great. If they revisit the plugging system I may reconsider buying, as for now, I can’t see a reason for buying it.

Update: After a week, the plug is leaking significantly. This is probably due to the angle of the puncture and the plug head not being able to maintain a seal since it's not parallel to the tire's inside surface (as described below). Looks like this situation will require string plug since these plugs cant be glued in place. :( I felt the tool quality was very good. Gun is made of heavier gauge steel parts and rasp seemed like tool grade steel that did a great job of rounding the puncture path. The problem was the mushroom shaped plugs are really designed to work with a puncture which is straight down through the tread, not angled. Objects often puncture a tire at an angle. When the plug head is pulled up at an angle, its harder for it's flat head to seal against the tire's inner surface. When I tried to fix my angled puncture, the plug was leaking after I pulled it up to seat it against the inside of the tire and I was ready to send this back. On my second try, I pushed the plug in, removed the tool and saw it was still leaking before pulling it up to seat the head. The plug's stem seems fairly ineffective at stopping leaks since it doesn't have any glue on it. Next, I slowly pulled the plug stem up until the plug head sealed up against the inside surface and stopped the leak. The directions tell you to pull up on the plug stem to seat it, but the plugs are heavily lubricated and will pull all the way out again without too much effort. If you pull the stem too hard, the plug head will start to deform like a blown-out umbrella as it gets pulled into the hole again. This is what I believe caused the first plug to leak. I'm keeping the tool because it's well made, and for punctures that are fairly perpendicular, I like this better than string plugs. My suggestion for maximizing the chances of a good seal is to spray some Windex or other soapy cleaner on the plug stem after removing the tool and pull the plug up until the leak stops. This way you don't risk pulling to too far out and causing it to leak again.
