I was having trouble with flats on the small tubeless front tires of a Club Cadet Lt-1 riding mower. I found this product easy to use following the below procedure. 1. Jack the vehicle off the ground so the tire rotates freely and raising it off the ground also prevents the tire from compressing in on itself after you let the air out. 2. Let the air out of the tire and then remove the valve using a metal valve removing tool. 3. Add the fluid by rotating the tire so the valve stem is at the top (always keep the valve at the top during this procedure) then place the fill tube over the valve stem and gradually squeeze the bottle till it becomes difficult to add more… then rotate the fill bottle downwards till more air enters the bottle— then raise the bottle to be above the valve and squeeze in more liquid. Keep lowing the bottle till it fills with air then raise it and keep squeezing in fluid till the bottle is half empty for the small tires and a full bottle for large tires. You can see the level of the fluid in the bottle by viewing it in the clear plastic side area. Then remove the fill tube and replace the tire valve and fill the tire with air. (always keeping the valve stem at the top so that no fluid leaks out) Now with the tire still off the ground, if possible –rotate the tire with your hands at highest speed possible for 4 or 5 mins to distribute the fluid. First CW and then CCW till all the fluid is dispersed equally inside the tire.. You should feel it rotate more evenly after all the fluid is fully dispersed inside the tire. Then remove the jack and drive the vehicle as a double check to be sure the fluid is fully dispersed. Using this procedure it totally solved the flat tire problem I had been having. Never under any condition use the plastic valve removing tool that comes in the cap of the bottle. Use a proper metal valve removal tool. The valves can take a great deal of pressure to remove and the plastic tool will immediately break.

Had a really small hole near the sidewall of my rear tire on my riding lawnmower. Came across this product… and I’m so glad i did. I will give you some pointers though – which some other reviewers mention, and some don’t.1) Let all the air out of the tire.2) Extend the hose on the bottle.3) Make sure the valve is at its highest point of the tire4) Fit the hose over the valve.IMPORTANT. Before step 4, unscrew the black top of the hose on the bottle. Use that to remove the piece inside the valve of the tire BEFORE proceeding. The bottle itself vaguely mentions this, but I totally missed it and skipped this. You need to do this obviously.5) Once the hose is over the valve and the inside of the valve is removed, squeeze the contents of the bottle in (amount depending on your use… my lawnmower tire was suggested the entire bottle, which I did).So here’s where it gets interesting. After step 5, reinstall the inside part of the tire valve and fill the tire with air. Once full of air, the bottle says that the escaping air draws the contents of the bottle to that opening and patches it. While that did seem to be happening, I went one step further, at the direction of some other reviewers.I took it for a leisurely drive, driving in figure eights… so that the contents of the bottle could get distributed. Being that my patch was near the sidewall, I was very concerned that it would be hard to patch this way. I have the luxury of having a bit of an incline across my backyard… so i just parked it across the inline and let gravity do the work.Left it for about 30 minutes. Drove it back into the shed and let it be. Checked the next night and the following night, and sure enough it’s completely patched. Checked the tire pressure and got it where it’s supposed to be and it’s good as new.For the price, this product is handsdown the solution you should choose. It worked, and I will definitely use again if I ever have the misfortune of another flat.

Tires on our 12 year old lawn tractor tires would not hold air due to dry rot. Would fill with air to mow lawn and the next week would have to fill the tires before mowing again. Replacement set would be over $300 which is hard to swallow when there is so much tread on the old tires.Saw this when looking for a product I had some success with on our bicycle tires and was impressed with the demo video and decided to give it a try. It has now been a month since filling the tires as indicated on the label and driving the mower on inclines and in tight circles to make sure it covered as much of the inside as possible. I have not had to refill the tires since!!! It is still holding pressure with no additional air needed. I am very impressed and happy on saving over $250.

Tried several times on a leaking tube tire. Would not hold pressure. This product works great on tubeless tires.

I use this stuff in all of my outdoor equipment (side by side, mower, tractor, trailers, etc.). I have not experienced a single leak in several years.
