Decent I guess. Time will tell if it works.

One of our cars has suffered from rim leaks and was driving me nuts. Constantly being asked by my wife to top off the tires on her car. When I replaced a damaged rim I asked the tire shop to look for the source of the leaks. They said the "alloy" rims had started to corrode and did their best to get them to seal but warned me they would likely leak again. This spring when I removed her snow tires I found 3 of her 4 tires had gone completely flat in storage. The fourth was the new rim which was fine. I considered buying new rims that won't have this problem but wanted to wait until her times need to be replaced. The batteries in the TPMS sensors are getting very low so likely these will need to be replaced as well. I thought to try some sort of sealant. Most of the products I saw were not rated for automotive systems and offered warnings about risk to the TMPS sensors. This seemed to be the only product rated for my application and claimed it would not harm our car's sensors. So I gave it a shot. I ordered the SUV package that came with an injector and two 8-oz bottles. I put 4 oz in each tire per the instructions. Overall the process was easy except the valve core extractor broken on one of the tires. I had to pick up a replacement at a local auto parts store. Also, injecting the sealant creates a small amount of pressure in the tire that, if one doesn't release by drawing out the plunger, will burp a small amount of sealant onto the rims. Fairly easy to clean up with WARM water and easier to avoid after the first experience. Drove the car around at a variety of speeds for 10-15 minutes (had errands to run) and waited to see what happened. Great results. Weeks later and the tires still have the correct pressure. I am not sure how long this will last but hopefully for the remaining life of the tires at least. I took one star off for easy of use / easy to install because the valve core extractor is made of extremely cheap aluminum and I am sure others will have a poor experience with it. Be forewarned and consider buying one before you start jacking up your car and letting the air out of the tires only to find you break the tool on a sticky valve core and are unable to complete the job without a trip to the auto parts store. I'll update this review in about a year to report on the long-term outlook for this product.

I have to admit, I was skeptical about whether this product would work. Just over three years ago, I bought new tires for my Ford Escape. I don't drive it much, but I use it for road trips, and I wanted to make sure it had good tires on it. I bought Michelins and paid dearly for them, but like shoes, I feel tires are an important investment. That said, I immediately began having problems with one tire losing air fast. It would be down by 10 psi in a week. I went back to the tire shop, and they ended up charging me $20 for a new valve stem.

Well, that didn't fix the problem.

I did some digging online and found out that the aluminum alloy wheels are the culprit, and that there's not much I could do to fix the problem. The rims lose their seal at the bead, and the only real way to fix the problem would be to purchase new - expensive - rims. I could have the tire shop take the tires off the rims and apply bead sealer, but they don't like to do that, as it makes for a mess the next time they put tires on. Plus, I had already paid a lot for the tires and a little more for their "fix" that didn't work.

After a while, another tire started losing air quickly. I ended up putting air in the tires weekly - fortunately I have my own compressor at home.

Finally - years later - I was doing some digging online and found this product and many folks gave it rave reviews. So, I decided to give it a try.

I followed the directions explicitly. Both rear tires were the problem, so I jacked up the rear of the car until both wheels were off the ground and let the air out. I removed the valve stem cores with the tool provided. I attached the included syringe to the valve of the first tire and carefully measured out the amount until I put 6 ounces of material into the tire. I then replaced the valve stem, aired up the tires, and began spinning it. I wasn't sure how long to spin it, so I pun it for a good 5 minutes before working on the other tire. NOTE: I spun the tire in both directions, just to make sure the product was as evenly distributed as possible. After filling the second tire, I spun it in both directions (which also spun the first one). After lowering the car off the jack, I drove slowly through my village to continue the distribution action. After about 15 minutes of in-town driving, I took the car on the highway for about 15 minutes.

Then, I waited. About a week later, I checked the tire pressures. I made sure the temperature was the same as the day I filled them last, as that will affect tire pressure. I was pleased that one of the tires was still at pressure, while the other was 2 lbs light. Another week later, I checked and the first tire was good, while the second tire was a few pounds light. I filled the light one and took the car for a 45 minute drive, spent some time there, then back home. 10 days later, I checked the tire pressure and much to my surprise BOTH TIRES WERE AT PRESSURE!

I am pleased as can be that this product worked. I recommend giving the product some time to do its job, as I experienced one tire taking longer to seal than the other. I was actually considering - as per instructions - adding another ounce of product to the still-leaking tire. I'm glad I waited, because now I know it can take a while for the sealer to seal the leak.

I highly recommend TireJect Automotive Tire Sealant & Bead Sealer. Follow the instructions, give it a couple weeks or more to completely seal, and I think you'll be as happy with the results as I am.

Fix A Flat reinflates tires. This product needs an air compressor and tires removed.
It makes leaking tires go away and doesn't make the rims need to be thrown away after use ðŸ‘

Got a big nail in the center of my EV tire. Removed valve core, added Tireject, replaced valve core, re-inflated tire, drove on freeway for 2 miles, leak was sealed. On the way to the tire-repair store, nail fell out, but Tireject sealed the hole. Highly recommend as long as you have a way to re-inflate the tire in a timely manner.
