⸻I recently installed the Ultraverse Tire Protector on my 26x4.0 fat bike, and I’m truly impressed.

I’ve ridden over gravel, glass shards, and rough trails without a single puncture. Installation was straightforward, and it doesn’t add noticeable weight or affect performance. If you’re serious about preventing tire damage and want peace of mind on your rides, this product is a must-have for 20, 24, or 26-inch fat tires.

These Ultraverse tire liners are a game-changer for fat tire bikes. I ride a lot on rough terrain and was tired of dealing with flats. After installing these on my 26x4.0 tires, I’ve had zero issues. The liners are thick, durable, and easy to install with a little patience. They fit perfectly and don’t add noticeable weight. Great peace of mind on trails and gravel. Highly recommended for anyone riding fat tires!

It's much harder to install than they say. I tried several method. This is what worked for me. I used two sided woodworkers tape to hold the liner in place. The ends were too curly to flatten out so I started about a foot in. Once I got it held in place with several inches of tape about a foot in I was able to stuff in the tube to hold in the rest of it in as shown in the instructions. The problem is getting it started. It wants to curl and twist and like wrestling with a snake. The two sided tape, essentially masking tape with glue on both sides, I was able to tame the snake. The last part is the curly ends. By the time you get to the ends you are in control. The product seems tough and likely will do the job. The challenge is installation.

This tire protector is awesome! Super easy to install and it really works. I’ve been riding over rough roads and some sharp stuff, and no flats so far. My bike still feels smooth, and I don’t even notice it’s there. Totally worth it if you’re tired of dealing with punctures.

This tire protector is great! It's very soft and durable. Easy to install and it actually works.

I love riding my bike. I got 2 flats in 1 week. I won’t be doing that again with this tube protector. It is now in both my tires. It is long enough and wide enough to fit any fat tire bike. So glad it came in a two pack. Thickness:Shouldn’t have any issues, it is pretty thickFit:It goes in easiest if you flip it over and put it in against the roll. You will fight with it more if you don’t.
