Terrene Yippee Ki Yay 27.5x4.3 Light - Fat Bike Tire

Thought I might be able to share a little insight: Overall this is a great tire, and a unique option in that it is the only tire of its size, it has significantly more volume than the 4”inchers, while being significantly smaller than, say, a Cake Eater 4.5, and thus a good option to maximize volume in a 177mm bike. (It fits on mine with a 65mm rim, but not an 83mm one). It rolls faster than it looks like it should, and has the traction that it looks like it should! Mounted tubeless like a charm and the tread (and perhaps more importantly the sidewalls) are wearing well despite what appears to be a softer rubber compound, even with occasional pavement use.

One thing I really don’t like about it (particularly reverent to mixed use riders) is that the stud holes all get packed with the little bits of granite prevalent on my local trails. They never clear themselves and every one of them is full. I really wish they weren’t there, as I have no use for studs.

Running as a front tire. Excellent grip, supple and rolls fast. Highly recommended!
