Review: 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.
Review: 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.

## Questions & Answers

**Q: hello...i want the one for streets.... not for all road....can you help me???**
A: these are good for on and off road use, I have tried street slicks but went back to these after I layed my e bike down 3 times, thats 3 more times than I have in 30 years. If you are running fat tire, stick to something with tread on it.

**Q: Are these better than stock Juiced HyperScorpion tires for some off-roading and light rain road conditions?**
A: Probably not better. They are very cheap. I run them on my ebike in the summers becuase ebikes wear the tires so quick. Its a decent option for ebikes but wouldn't recommend it for anything past light trail riding.

**Q: Where can I get tire liners for my fat tires size 20 x 4 ?**
A: I've had great luck using Mr. Tuffy tire liners (ASIN# B078FHD1ZH) in size 26" x 3.1" on my fat tire bikes with 20" x 4" tires.
All I've had to do is shorten the liner a bit for my 20" tire, which can be done simply with a pair of scissors.

**Q: Will this fit a radrover 5 for front and rear tire?**
A: yes. should fit fine.

### ⭐⭐⭐⭐⭐ Perfect, and easy to install
*by K***T on September 6, 2024*

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
*by W***E on July 16, 2023*

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.
