20x4
Good tire. Mine were stamped "Mongoose" like the first photo, not "Chao Yang", but they're the same tires either way. My old ones that came with the bike (heybike mars 1.0) were Chao Yangs and the tread and everything is identical. I got over 1k miles out of my first rear tire, with a lot of very rocky trails and off road riding. When I finally got a flat I just decided to get new ones since the tread was almost gone anyway, and my sidewall was coming apart. I'm hoping to get another year and 1k or so miles out of the new tire. The front seems to last longer, it still has a ton of tread.

Perfect, and easy to install
Got this as a replacement for my ebike and let me tell you, this tire is better than the tires that come with the bike! It it easy to install and the size fits perfectly. In addition, the tire rides smooth AND it is quiet while riding.

Excellent replacement for OEM Kendas
Solid bead, good tread, lighter and seemingly more durable than the original Kenda tires that came with my Aventon Adventura. These are good tires These Mongoose tires fit perfectly and as depicted in my photos, match the OEM tires perfectly. After test driving I noted they were well balanced and had great traction with minimal road noise. I definitely recommend these tires for fat tire bikes.

great value...seats great...rides great...easy install
300 miles on these tires! I really like these tires! 300 miles..easy to install....they ride smooth and terrific!!! Perhaps a fraction smaller than original tires, because I am unable to hit the top speed on my Lectric XPeak. Side walls a little on the thin side as well..hence 4 stars. Maybe hard core bikers may look at other options, but I am extremely happy with this tire!!!

Quieter than OEM tires
I needed to replace the factory Kendra tire on my bike. I really like the tread pattern on this tire versus the factory Kendra. It seems to ride a bit smoother and quieter. Appears well made with quality material. I liked the fact that it didn't come packaged rolled up like some do.

Mongoose 20"x4" bicycle tire a possible replacement tire for Schwinn/Stingray chopper (20"x4-1/4")
After many hours of searching every possible web site & all local bike shops, we couldn't find a replacement tire for the Schwinn Stingray chopper we are refurbishing. Most websites with tires that would fit charged as much for shipping as for the tire itself. When we saw Amazon's Mongoose 20"x4" bicycle tire, we thought it could be a possible replacement tire for a Schwinn/Stingray chopper bicycle , which has a rear tire size of 20"x4-1/4". The Mongoose 4" tire fit and seated perfectly on the 4 1/4" rim, but it had too a high profile to put onto the bike without major remodeling (remove the fender, cut or grind off the fender mounting bracket, change rear brakes to accommodate the Mongoose height, change the way the chain rides so it wouldn't constantly rub on the tire's side, etc.) We finally found an exact, factory-recommended Ivonna 20"x4-1/4" tire, with Stingray on the tire side in raised letters, at a reasonable price on another site. But the Mongoose tire was easy to install onto the rim, easy to remove, and Amazon made it easy to return for a refund. Thank you, Amazon!

IT IS NOT A MONGOOSE made by a Chinese mega producer
It is a good tire 4 stars is do to the misleading description. And it is just good not great. The range of air pressure is small so it is a little bit stiffer then I like.

Lasted 3000+ miles on roads
The picture is of the 26x4 tire after 3000+ miles on pavement! It lasted a long time! I got these to replace the tires that came on my mongoose dolomite. The original ones lasted over 3000 miles on pavement which is really good. I tried some Kenda Juggernauts and they only lasted about 1000 miles, So these are a great value. There are Some other reviews saying they are counterfeit because they say CHAO YANG and not mongoose; but that Both the original tires on my mongoose dolomite and the ones i got on Amazon say CHAO YANG on them. They don’t look special but heck they lasted 3x as long as a Kenda Juggernaut, and they are actually in stock and available during the Coroneys plague, so hey I’ll take it.

Das Profil des gelieferten Reifen unterscheidet sich sehr von dem auf der Abbildung auf Amazon! So ein Profil gibts billiger!

Value for money
I have a Costco fat bike that bought for $500, the problem is that the tires were for summer, and I wanted them for winter. So I didn't want to spend lots of money on tires and found these ones. These tires were the perfect solution. Even when not designed for studs, I was able to put studs on them that are of the screw in type sold in Amazon as well. Tires have a nice thread and do a good job in the snow. Very happy with my purchase.

Es tremenda
Llevo 3 meses que no he inflado la bicicleta, y vaya que aún se siente muy inflada. Aunque es obvio que no va a aguantar pasar por cosas extremadamente punsantes, definitivamente si no quieres gastar mucho, esta muy bien.
