Great E-Bike Tires, Easy Tool-Free Install
The 4 tires came folded into 1/4th size with zip ties and when unfolded were puckered (see photos). I placed them near a space heater with clothes pins pulling the beads together then rotating them ever 15 minutes for 2 hours. I then placed them in a cool work room (received in winter) and let them sit for a day. The puckers came out nicely. The tires were easy to install tools free and remove on electric quad cycle. I placed the inside flexible bead over the rim with bare hands (correctly positioned the rotation arrow and the name aligned with the valve stem) then inserted the softly filled inner tube into the tire, then pressed the outside flexible bead into the rim channel. The tire was centered then inflated to 16 pounds of pressure. The tires fit well without rubbing on the fenders. See photos of the install and tread comparison with the removed tires. The tires have been ridden through 4 inches of wet snow, gravel roads, gravel & dirt bike trails (80% of my riding) with great traction. Riding on pavement (20% of my riding) they roll smoothly with great traction but are noisy much like snow tires on pavement. My prior tires I would get 1 year out of riding. I will follow-up in a year to let you know how they do. So far no punctures with almost daily riding. I am very pleased with them.

Still good after total rim failure.
Installed on my little brothers z8 ebike. Definitely quality as he jumped a curb and broke 10 spokes. He's also heavier too so these are rated.

Great product
Very nice tire and tube for an ebike. It's well built and hopefully will last for a long time. By the way it looks great on my bike.

Great product.
I have bought several of these. The first one I put on my back wheel lasted 8 months before running over a nail. The one I put on the front tire is still lasting.

⭐️⭐️⭐️⭐️⭐️ Excellent Traction and Durability!
I put these fat bike tires on my mountain bike, and they’ve completely transformed my rides. The grip is incredible — they handle snow, sand, and loose gravel without slipping. The tread is deep and aggressive but still rolls smoothly on pavement. Installation was easy, and they’ve held air really well so far. After several long rides, there’s barely any visible wear. Definitely worth the price for the quality and performance. Perfect for anyone who loves off-road adventures or just wants extra stability on rough terrain!

Bad inner tube
While I am sure that the tire itself is good, I've only had the inner tube for a month or less and the inside ripped right near the valve. I am not happy with that at all. I will not be purchasing from this brand again.

Better than expected
Was getting too many flats & needed a tire that was heavy duty. After I ordered I found a site with lots of neg reviews and told Amazon to cancel my order..TOO LATE! When tires came decided to do a comparison my old factory tires as long as both were here. New HD tires weight 5.4Lbs ea. old tires 3.35lbs, they are just about 100% thicker, with no flats to date. They were easy to install and seem to have good traction my riding is off road with about 5% on gravel where they do sound different (hollow sound) I have noted about 10% reduction in mileage could be just my riding is past 60 miles. Have you noticed that most of the Made in China tires look like the have same tread style?..these look the same but they also have the extra belts giving more protection from flats. Happy with purchase

This tire is thicker than the last one and appears to be good quality

It's not as anti puncture as it holds firmly on the ground. The anti puncture feature unfortunately didn't work well for me twice, but what I really like in this tires is the Way it was built. That thing holds you on the curve like a pro racing, many times better than the original tires that came on my bike.
