Tires Big Smoothy 26 x 4.0 Black Fold/60 - T090203

Its a great tire. the tread looks minimal in pictures, and it is. But in practice its perfect for gluing the front wheel to the ground in cornering on city streets. Also the tread is not enough to cause any noticeable vibration. It truly is a Big Smoothy.So much for the good news. The bad news is this tire was manufactured to poor quality standards. I have put many thousands of miles on Arisun tires as well as their parent company: Chaoyang (Arisun is the EU/North American brand for Chaoyang, who is a huge tire mfr on the Chinese mainland).I have always found Arisun tires to be a step up from the parent Chaoyang brand, and assumed it was because of higher expectations for quality in these markets. But the other reviewers who have complained about the tire being out of balance have nailed the problem exactly. Its *horrible*.I have seen the Origin8 Supercell (which is a rebranded Chaoyang Sandstorm) have a nasty jig to the side which causes the bike to shimmy. I've seen the same thing with a Chaoyang Big Daddy (also sold as the Arisun Big Fatty). But those are rare. Since so many others point it out I am assuming there is a larger problem here. The tire does not jig to one side or the othner... it is heavy in one spot only, centered, and as such the wheel 'hops' quite badly.It would have been enough for me to immediately return the tire as the hop was patently unsafe, but I have double-wall, 80mm rims and I was able to throw on a pair of motorcycle wheel weights (purchased from Amazon) to render the wheel somewhjat acceptable. We'll see as I think its right on the edge of crossing over from annoying to unsafe.

I put these on my fat eBike to replace the noisy off-road tires I had on it. I think these will work out well. A brief (3 mile) test ride felt a little strange as these have a ton of road grip to them (especially in corners). The handling will take a little getting use to, but I think they will work out well. They are nice and quiet when rolling on pavement which was the main reason for the purchase.I'll update this review after a few hundred miles and let you know if I still like them.Update after 3 months of commuting: I still really like these tires. I have the benefits of a fat bike with a smooth running tire. I have about 600 miles on these with no issues / no flats. Tread still looks like new.

They have a defect of circumference, there is a lump of 10 mm on the tread, that creates ossilation while rolling, it is a little unpleasant and I separate myself from this fact, it is a pity because the concept is good, the inflation is at 1.4 bar, probably at 0.8 bar the problem is not noticeable.

For starters the weight is 3.1 lbs. rather then 1.8 lbs. After that the quality is poor at best. If your bike has tight tolerances do not buy these tires. They are not round.

Not sure but I took a chance on these to replace heavy slow moongoose tires on my cheap fat build. I ride mostly on road and packed trails so I think the minimum tread will he ok. I'm hoping the wiegjt and lower rolling resistance will add some zip to my two wheeled tank.
