Fix-A-Flat S60430 Aerosol Emergency Flat Tire Repair and Inflator, for Large Tires, Eco-Friendly Formula, Universal Fit for All Cars and Small Trucks/SUVs, 20 oz. (Pack of 1)

There was no pressure in the can. It would not even inflate a bicycle tire. Be careful there is no amazon refund or return with this item!

I have a 2024 Model Y Performance and was always a little concerned about it never having a spare tire. As a result, I decided to pick up one of these fix a flats last week to keep in my trunk. I'm glad I did because literally a few days later I go out to my car in the morning and see a huge sheet metal screw sticking out of the tire and the car telling me that it's dangerously low tire pressure. After removing the screw I can see (and hear) that this tire is not going to hold any pressure and will need replacement. I needed my car back in action in a hurry and a tow was going to be crazy expensive and slow to arrive... I didn't know if the fix a flat would be able to work on a puncture of this size but I figured I would give it a shot. After following instructions I slowly drove it around for the 2 miles it said to and looked at the damage....still leaking...so after 15 minutes of coming to terms with my whole day being lost, I checked it again...no leak!...I topped it off with my portable inflator and waiting 10 more minutes....it was holding 38 psi without issue...so I proceeded to drive it to the Tesla service center 10 miles away and got a replacement tire within an hour and was able to go about my day...so this basically saved the day. A+

Pumping a very sticky white substance into your tire is going to be clumsy and messy. Expect a little leakage from the tube, make sure that the can is securely connected to the tire nozzle, be sure to shake the can numerous times. When finished it’s critical you take the car for at least a 5 mile drive to move the liquid around the inside of the tire. Very good for emergency use, or if you have a really slow leak that cannot be fixed normal ways. It can securely clog the leak for a long time if used properly. Be sure to pump air into the tire when finished to the recommended inflation.

It is as advertised. It just works.

Has worked in the past but thankfully haven't needed to use this one yet.
