Should have bought this years ago!!!
I live at the end of 25 minutes dirt road top of red Mountain, Co. On the 3rd flat in 2 weeks I ordered this kit instead of putting a spare on and driving to town 1 hour away. and knock on wood its has held going on 3 weeks. I jacked up the car, followed the instruction and wow easier then going to Big-O. Love it and told my Kids they need to get it also.

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.
