Review: great performance and peace of mind! - I've been using Muc-Off Tire Sealant for a few months now and it's exceeded my expectations. Installation was quick and mess-free thanks to its smooth consistency, and the UV detection feature is a clever touch for spotting any issues early. What really impressed me was how quickly it sealed punctures—I hit a thorny section on a trail ride and barely noticed the leak before it sealed up within seconds. No pressure loss, no stopping, just confidence to keep going. It’s lightweight, eco-friendly, and doesn’t clump like some other brands I’ve tried. Highly recommend it to anyone who wants a reliable sealant that just works when you need it most!
Review: Easy to use and seems to work - I have waited to post this review until I have actually had a puncture. I went tubeless at the start of the year, and after some research decided to use this sealant in my specialised pathfinder pro tyres. The sealant comes with a tube attachment, that can directly fitted to your wheel valves. There are markings on the bottle so it is easy enough to guestimate the amount of gunk you have put in. When you do get a puncture the gunk is easy to spot. After about 1200 miles, I had a puncture that was a lot bigger than I realised. I thought it was just a small hole and I was able to ride my bike for about 150 miles (inflating every other ride) before deciding to do proper fix. The fix entailed pushing one of the large tyre fixing strips into the hole using a puncture repair tool. Overall this was a lot less hassle than punctures I have had with innertubes where it has sometimes been too cold to change the tyre, too muddy to see the tyre or I have missed glass embedded in the tyre and ended up puncturing the replacement tool. So far so good.

## Questions & Answers

**Q: is this C02 compatible**
A: Most likely.... Alot of bike shops or enthusiast's use compressors to inflate tyres after applying tubeless sealant to seat the tyre etc and I've seen riders carry c02 cartridges out on the trails to re-inflate tyres.

**Q: Does this 1 litre bottle come with a tube to pour into valve?**
A: Yes, came with a clear rubber tube that goes over the valve

**Q: Can this be added to tyres that have another brand of tyre sealant already in the tyre**
A: There's no way of us answering this without knowing what the other sealant is.  Best option is to wipe out the old sealant, properly clean anything off the bead, seal and top up again.  If you're going tubeless then you'll be wanting to check sealant levels and re-seat the tyres every 6 months or so so best to start again with a single mixture.

**Q: How many wheels does 1 litre do?**
A: Depends on wheel and tyre size, but approx 10 for a 27.5 wheel mtb. There is a guide on the back of the bottle

### ⭐⭐⭐⭐⭐ Expensive compared to others but great all the same.
*by J***, on 11 July 2022*

First time converting tubeless ready to tubeless. I had read a number of different ways of doing this and decided that after fitting the valves I would seat the tyre to the rims using a co2 canister as I have no access to a compressor and a track pump sounded like hard work! I didn't want to risk spilling fluid everywhere trying to seat the tyre after pouting it into an unseated tyre. I had tubeless ready rims and decided to go with the already installed spoke band that was on the wheel (aparrantly you shouldn't do this!). After inflating without this product, I had a fair size leak from one spoke... Decided to go for it based on the previous reviews and removed the valve core and used the tube on the bottle to put the fluid in through the valve. No mess at all, and the fluid stopped the leaky spoke after about 5-8 minutes of doing the tyre shuffle, bit by bit it went from a worrying liss to inaudible. I only used the recommended amount and am running 29rs X 2.25. I needed to inflate the tyre a couple of times as pressure dropped initially. Thought I had messed up the whole process and would need to remover the tyre and start again! How wrong was I? Have checked the pressures every couple of days since and have lost nothing! There is also a handy window on the bottle with a guage to show you how much you have added to the tyre and there is probably still enough for when I need to service them at least twice more again! Yes, a little expensive compared to other options but I think muc off have "Nailed It"... 😏
