Quick fast repair got a puncture in my inch new tyre .side wall Used to get home , tyre still up now 3 days later . Amazing stuff

Although I have had one of these in my car for years I have never had to use one before so have always been a little wary. Then my wife got a puncture the other week and was stranded by the side of the road. The puncture she had was quite large to say the least. The tyre was completely flat and when I tried to pump it up I could hear the air coming out and see the damage so I thought the tyre would not repair. Figuring I had nothing to lose I decided to try it anyway. I emptied the whole can in and filled the tyre with air. I then drove a couple of miles very carefully in the direction of a nearby garage. By the time I got to the garage the tyre was still full of air and there was no sign of leakage. Because the tyre had been completely flat and she had needed to drive it a little way to get off of a main road the tyre was buggered and needed replacing, the garage ordered a new one which was not available until the next day she I drove it 4 more miles home. In the morning my wife drove it again (without needing to add more air) back to the garage. So this stuff really does work and it works on pretty large punctures. Definitely recommend.. ----------------------------------------------------------------------------------------------------------- I like to try and review all of the products I buy on Amazon in order to help other people out.

It’s good and easy to use

Tldr; Does the job for small, slow leaks. 3-4day = 1.5-2bar loss. I had a very small leak on a 18 inch tyre, I chose the medium as the tyre was low profile-ish, so the volume within was reduced. It was so small I couldn't identify the leak area, and the tyre held workable pressure for 3-4 days. With tyre pressure at around 1.5bar, I used the entire can as instructed, this brought the tyre to about 2.4bar. I topped it up to about 3bar, thinking I'd loose a little pressure before it sealed. However, as the can is aerosol, it cools when in use, so expands when warms. This happens when you drive as the tyre gets warm, and so I ended up with a tyre pressure the next day of above 4bar steady. It had sealed quickly and increased pressure. I vented the tyre back to normal pressure, and haven't had a problem since. It's held up for two months+. Would recommend for small leaks. I would think anything like a nail would require a plug repair. And if on tyre wall, the tyre has to be replaced. But, it may save you in a pinch for again, small, slow leaks. If your tyre looses pressure within 12hr period, I'd say this is 50/50. Above that and you've got a good chance. Below that and the leak is too fast, indicating a larger hole in the tyre. I don't often recommend must haves as everyones requirements and abilities are different. But this works well for what it was designed for, it's relatively cheap, lasts a while in storage, and is the size of a can of hairspray.

Good to keep in the car just in case

Bought this for 16 " wheels which are well within the size mentioned on the can/description. Was simple to use attach to tyre valve, and then turn on. The tyre was barely inflated to half full despite being well within the limits mentioned on the can, and also being too small for the next size up. It did fix the puncture, though had to use a foot pump to get enough pressure in the tyre to drive.

Excellent low cost product for curing slow leaks in tyres. I’ve used this in a number of cars where air was escaping past the rim of the wheel. In one instance the tyre was deflating in 24 hours. One application cured this. No nasty gloopy residue so good news for the next tyre change. Recommended

hopefully never needed. Portable and compact.

Contents went everywhere, what a mess!

Like a fire extinguisher I will use it only in emergency so cannot tell if it is going to be any good. I hope so! Will be able to report more after use.
