Holts Tyreweld Puncture Sealant Emergency Tyre Repair Foam Car Puncture Repair Kit Sealant, Quick & Easy Flat Tyre Foam, Drive Up To 100 Miles, No Tools Needed Unscented, 400ml , Pack of 1

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.

Seems ok, cannot comment because not used

Works well and is easy to use

A great product for a very reasonable price compared to manufacture's supplied inflation kits. Looks very simple to use with safety being an important issue - don't have to stand at the side of the car whilst it's inflating. Came with a very long expiry date. Hope I don't need to use it, but it's there!

It looks very well made exactly what I wanted My current on is out of date and looks like it is very easy to use

It might have worked but half of it leaked from the valve on the can and onto the floor. So not great.

Bought this to inflate a completely flat wheelbarrow wheel. Achieved a successful result but did find that some of the foam escaped out of top of the can for some reason which made things rather messy. The escaped foam easily washed way with water though.

Awesome stuff 😊👍

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.
