A Must-Have Emergency Kit for Every Vehicle, Especially ATVs!
I recently bought this 54PCS Flat Tire Repair Kit with Air Compressor, and I’m seriously impressed. It’s one of those products you hope you won’t need—but are SO glad to have when the time comes. I used it on my ATV after catching a sharp rock on the trail, and it saved the day. The plug worked perfectly, and the air compressor had my tire reinflated in just a few minutes.
What I really love is how complete the kit is. From cars and motorcycles to trucks and tractors, it’s got everything you need to handle a flat. The tools are solid and durable, and the case keeps everything neatly organized. It’s compact enough to toss in the back of my truck or ATV storage box without taking up too much space.
If you ride ATVs in remote areas like I do, this kit is a no-brainer. It gives you peace of mind and saves you from having to hike back to civilization. Highly recommended!

Kept it in my trunk for months — used it once and it saved me
I’ve had this AUTOWN tire repair kit sitting in the trunk for several months as a “just in case” thing. I have only had to use it once, but the tools and compressor held up and it actually helped me get out of a bad spot where I didn’t have a spare tire available.
Just to be clear, I wouldn’t call this a permanent fix. It’s more of an emergency repair to get you back on the road. In my case it did exactly that. Afterward, I went to a nearby tire shop and had the tire repaired the right way.
Overall, I’m really glad I had it in the car. Just using it once has already paid for itself.

This product work so well it will surpass your expectations it did mine
Size: 1-Pack (32 oz)
This product is well worth the price. I had a small branch puncture a hole through the sidewall of a tire on my 4 wheeler. The hole was at least 3/8” and was done by a tree limb so the edges were jagged. I followed instructions on the product yet the whole time I thought I was wasting my time and the product most likely. I was pleasantly surprised and wrong. It sealed as soon as re inflated the tire and hasn’t leaked down in over 6 months now. I was so impressed I put 2 packs in everything I drive on road and off road.

Best fix for flats that I've ever used
I have a large zero turn mower that is 10 years old and had a slow leak in the front tire. I tried fix a flat but even a full can would barely get any of the product into the tire and would end up oozing around the valve. After a long search, I found FlatOut. I was reluctant at first because it required removing the valve core, which I had never done. (I'm a 60+ year old female.) But the ratings were so high and the fact it was made with Kevlar, changed my mind. And I am so glad!! The instructions were so simple, core valve came right out (and the tool and new core valve is included), the tube that you pull from the bottle, fit snuggly on the valve stem yet was not difficult to put on. I elevated the bottle, added the amount I thought it needed, removed the tube, pushed it back in the bottle, replaced the cap, and then put the new valve stem back in. It only took a few minutes. And no mess! I had put on rubber gloves, expecting some to spill but it's a thick liquid and does not seep out anywhere it's not supposed to! I filled the tire with air and checked it each day for a week to make sure there was no leak before I used it. I then mowed some rough ground that is hilly and rocky and when I was done, the tire was perfect. I was so pleased I did the same thing to the other tire that never lost any air because I didn't want to wait for a leak.
BUY THIS PRODUCT if you are tired of messing with slow leaks or flat tires! I will never use anything else. I purchased a package of core valves and taped them on the bottle so I'll have them when needed! I would give this product 10 stars if I could. It states on the bottle this product was used in the military, so it really has been tested. Thank you FlatOut for a product that actually does what it says!
