4.0 out of 5 stars Better Than Expected - UPDATE
Reviewed in the United States 🇺🇸 on July 16, 2021
UPDATE: Have over 300 miles on this tire now. No problems at all. Seems to wear very well. ORIGINAL REVIEW: Purchased this 20X4 Mongoose Fat Tire to replace the Kenda Krusade that was stock on my Rad Mini 2019 (non step through). Krusade was starting to wear out pretty bad at about 1200-1300 miles, but Rad has not had any Krusades in stock for a long time with no answer from Rad when they would be available, other than the "soon" rhetoric. Not their fault because the China supply chain is terrible and very unreliable, and maybe even intentional. Anyway - when the Mongoose arrived I was displeased that it is not a Mongoose, as many reviewers had noted, and it is much thinner than the Krusade. But, I needed something and went for this Mongoose (Nongoose). Tread seemed to be fine for my use, so I went ahead and ordered it. I mounted the Mongoose on the rear with the Rad Mini at 1700 miles, with little trouble other than you have to be sure to bead the tire on both sides so tire is symmetrical and bead is on wheel properly. OK - went for test ride. Felt fine and after about a 10 mile test I was impressed with the ride, a lot. It is quieter than the Krusade, and grip and road-feel is excellent. All and all I am very pleased with it now. I only have about 25 miles on it so far, but it feels good. Don't know about how well it will wear or how long it will last, but it is definitely a decent replacement for the Krusade on a Rad Mini. One of the things I like about the Krusade from Rad is that it has a reflective strip on both sides of the tire for high visibility at night. The Nongoose does not. The Mongoose is a good tire for the price.

4.0 out of 5 stars Choa Yang Mongols tire, not Mongoose Mongoose tire
Reviewed in the United States 🇺🇸 on November 10, 2021
Been biking over 50 yrs now, my first 4" wide bike tires, but it took almost a half hour per tire to mount. The bead was so warped I had to inflate/deflate/massage/repeat over 10x/tire. My short test ride went well enough, after 1200 miles i took another pic of the tred. These say Chao Yang on them but they are designed for Mongoose bikes. I don't think Mongoose makes tires, they make bikes & spec the tires that go on their bikes. I wore my Juggernauts bald in ~1000 miles; I ride hard & am not afraid to leave my blood on the trail. These Chao Yangs ran 1200 similar miles & still have some tred left so IMO Chao Yang is more durable than Juggernauts. These Chao Yangs w/1200 miles on them are starting to get unstable in turns on loose dirt so I'm replacing them...with another set of Chao Yangs. The last ones I got, I was concerned they were Chao Yang, not Mongoose, but 1200 rough rock hopping & power sliding miles later I'm reordering Chao Yangs.

4 stars bc I don't like Chao Yang claiming they are Mongoose. Otherwise I'd give 5 stars. Great tire overall.

3.0 out of 5 stars Tire does not match thread pattern as advertised
Reviewed in Canada 🇨🇦 on July 6, 2019
Thread pattern is not as advertised. It's aggressive and seems to grip well off road...not very smooth on pavement. I think it will work well for mud and snow. Only have it 3 starts because of false advertising.
