STP Tire Fix Flat Tire Sealant and Inflator, 16 oz, Instantly Seals Leaks and Inflates Pressure, Essential Item for Your Roadside Emergency Kit

I just bought two of these-- one for my wife's car and one for mine. Mine is to replace one that I used recently, and if it didn't save my life it saved me a lot of time, inconvenience and money.The pressurized sealant can that I had was a different brand, but functionally the same thing. I was 140 miles from home when I got a nail in my tire and it went dead flat. Fortunately, I wasn't driving at the time-- it lost air overnight. I had to get home, and buying new tires where I was would have been either impossible or very, very expensive (my car is all-wheel drive, so I would need four new tires). Plus, no spare in new model cars, which is crazy. So I filled the flat tire, drove immediately to a service station to fill the tire the rest of the way, and started home. I pulled over every half-hour or so to make sure that it was still holding air.Miraculously, I was able to drive all the way home and went immediately to our local reputable tire store to buy new tires. Not cheap, but trustworthy and unavoidable under the circumstances. I don't know what I would have done without the tire sealant, but I know that it would have taken much longer (possibly days of waiting) and more expensive by an order of magnitude. So this is now mandatory equipment for me. I get it that the product does not seal all flats and might not work as well (or at all) next time, but it is still cheap protection and it worked like a lifesaver the one time I needed it to work, so I am all in.

My tire had a slow leak, which was dropping less than 1 PSI per day at first, but over time became 5+ PSI per day.This solved the issue and the tire has been holding full pressure for a few weeks now. Ideally it will last another year until the car is ready to get 4 new tires - time will tell.This may cause your TPMS light to come on as the solution will get into your pressure sensor, however it states on the label that this will likely happen so it's not really a con. The residue is supposed to wash off with water only when it does come time to fully replace the tire.The product is mostly marketed to fix medium side tire punctures like nails as a short term solution, but it does seem capable of working as a long term solution for slow leaks as well.

I bought this for my motorcycle incase I get a flat way out away from any services to help me out. I checked out other reviews and felt this was the better one to purchase. I like what I see but haven’t actually used it and hope I don’t have to because it makes a mess of your rim inside on a tubeless tire.Something to consider if you didn’t know that.I can only say I trust it will work for an emergency.

Had a small leak and couldn't find it. Put half a can in and it sealed it. It's been 3 months and still no leak. Works great.

One of my run flat tires had a slow leak that would cause it to lose 2-3 psi overnight. Most people would recommend to get your tired patched but I heard really good things about this STP tire inflator so i decided to give it a try. Worst case I would need to go down to the tireshop and have the tire cleaned and patched. I started by leaking some of the air by partially connecting the sealant's hose. I used about half the can and started driving per instructions. I noticed that my car's integrated tire gauge monitor was having issues with the affected tire however it went back to normal after driving around the next day. Its been a week and my tire has not lost tire pressure overnight anymore.

I used this because I drove past some shattered glass on the highway. Few days later, one of my tires actually went really flat. Used this and my tire has actually still remained intact even after 2 months. Quite an amazing product. Always have 1 in my trunk just in case.

I assumed this would not fill my tire but to say it till safely get you off the road is circumstantial. No matter what, you should have a tire compressor in your car but don’t assume this one can will get you off the road safely. Other than that, this will work for what it’s intended for.

This is a great product---H2O soluble is wise move---seller is excellent, will repeat
