Advanced clincher technology from Hutchinson yields a durable high-end tire that is constructed with three rubber compounds which optimize tread life and provide progressive grip in corners.
At the core of the tire is a supple 127 tpi casing. The way Hutchinson spins and weaves the casing yields a near perfect product with better results than competitors using 2-3 times as much tpi count casings. The casing itself offers a nice blend between being nice and stiff for cornering but soft enough to feel resilient and not too choppy.
The triple compound tread is task specific. The wide center tread is firm for fast rolling. Sandwiched on each side of it are two lower density compounds for gooey grip in when cornering. So what you get is two different durameter compounds for two different tasks. Underneath the tread lies Hutchinson's Kevlar Pro Tech strip. This Kevlar strip or belt increase the Fusion 3's resistance to perforations and punctures without affecting performance.
All-in-all, we have plenty of experience with the Fusion tires. They are a wonderful product that has low rolling resistance and really grippy cornering abilities. Until the tread is completely worn down, they will not give you issues with flatting either. The amount of mileage you will get from the Fusions 3 is respectable considering how much performance they offer.
I purchased these this spring for a second bike, not ridden much. the rear got cut in the casing in two months. Both tires had the rubber come apart at the seams. right on the top of the tire. I have never seen this. I am tempted to return them but I have had them for six months. Live and learn.
Pros: They hold air well.
Cons: they fall apart.
This tire rides well but the sidewalls are not durable and tire not suitable where roads are not free of cracks, sticks etc. I have had Michelin, Vredestein, Hutchinson Fusion 2, and Conti and these were the least durable tires I have ever owned. I went through three of these tires in one season, each with cuts on the side. The last one lasted for two rides before I got a side cut that caused a bubble. I am careful about inflation pressure and ran these at 125 and 110--I weigh 205. I also note that these tires are larger than a standard 23--in setting up a cyclocomputer, they should be treated as a 25. Personally, I liked the larger size and the tires were otherwise fine. Switched to Conti GP 4000s due to lack of durability.
Pros: Good ride, cheap when on sale
Cons: sides are prone to cuts
