Excellent Tire for road and trails
Excellent tire for road and trail. This is my 3rd set of tires on my e-bike and I will re-purchase when needed. This is a real tire. It comes in a tire shaped box, not folded because it actually has a rim bead. It fits on rim better and hooks into the rim for a firm fit. Tire pressure rating 5 to 30 psi. I have mine at 20 PSI and it rolls so smoothly. It grips the ground on straights and turns. It feels very stable. Huge improvement to riding. And very quiet. Which is not what you get from the factory knobbies

Well made, high quality, good ride
Recently I ordered an e bike on Amazon. But the one I ordered came with knobbies and since I commute mostly on pavement, I wanted a smoother ride. So I did some research and found people having very good experiences with Ultraverse tires ( one gentleman claimed to have 14,000 miles on a set!!). The tread looked like a good road design that could also be used in grass and gravel if I need to go around cars and other pedestrians. So I bought a set. My new ebike arrived and I pulled it out of the box and immediately replaced the stock knobbies with the Ultraverse tires. I also added FlatOut to the tubes to help seal any punctures. Though one of the selling points of the Ultraverse tires is that the tread is thick and the sidewalls are stiff. I don't expect many flats with these tires. I have to say, I absolutely LOVE the ride and handling of the bike with these tires! They're stable, smooth rolling, and quiet. They seem to be a really good combination of hardness for longevity and rubberiness for grip. And I like the looks, they look like motorcycle tires. if I ever need to replace them, I will definitely look for another set of Ultraverse tires. Edited to add: After hitting 350 miles today, these tires are amazing! It's almost comical how well they transition from pavement to grass to gravel to loose leaves... the bike just feels completely stable under all conditions, even rain. Can't say enough good things about them. In fact I just bought a set of 20x4's for my other e-bike. Keep up the great work Ultraverse!

Tough, Grippy, and Perfect for E-Bike Adventures
I recently upgraded my e-bike with the ULTRAVERSE 20x4 Fat Tires, and I couldn’t be more pleased. These tires are built like tanks—perfect for both urban rides and off-road trails. Build Quality & Design: The construction is seriously durable. The high-density rubber compound and thick sidewalls give me confidence on rough terrain. These tires feel solid and well-made right out of the box—no signs of flimsy materials or weak points. Performance: I’ve tested them on pavement, gravel, loose dirt, and even some snow. The directional tread provides excellent grip and control without feeling sluggish on the street. They roll smoothly on asphalt and still handle rough patches like champs. The wide 20x4" size gives that cushioned, stable ride I love, especially at higher e-bike speeds. Installation: Swapping out the old tires was straightforward. They seated well on my rims without any issues, and I had both installed and ready to ride in under an hour. Street & Trail Versatility: These really shine in versatility. Whether I’m commuting through the city or exploring forest paths, they handle it all without compromise. They also seem more puncture-resistant than my previous set, which is a big plus for longer rides. Value for Money: Getting 2 tires at this quality level is a great deal. It’s clear ULTRAVERSE put some serious thought into performance and durability. Final Thoughts: If you’re looking for a rugged, all-terrain fat tire set that performs well on both trails and city streets, the ULTRAVERSE 20x4 tires are a fantastic choice. Highly recommended for e-bike and MTB riders who want grip, comfort, and reliability.

Extra mile bike tire.
This is a top tier tire, for what is commonly available. This tire is heavy duty. More stable than others and very good road grip. I feel it will provide excellent puncture resistance, and has for a month now. I travel some 14 miles a day through industrial areas for long straight aways. No punctures. I still use slime, just in case to help me get home. Just for extra peace of mind.

Rides nice. Good quality
Shipped in full size box. Side walls are nice and hard but the logo are only on 1 side. The treads are thick and does pretty good going up loose dirt road. They weigh 4 lbs 4oz each. Rides quieter than stock 20x4 knobbies. Recommend inflation up to 30 psi but they are smooth at 25 psi. Comes with tire pry tools. Install was straight forward.

Good investment
Great tires. Big upgrade from the stock ones on my Engwe E26. I had gotten 3 flats in a month and had had it. I love the tread pattern and they were honestly easy to mount. Had to stretch them a bit but they do come unfolded. Great look. Only complaint is they seem noisy. Everyone says they are quiet...idk about that. Either way, good grip, better than stock tires on bumpy roads. Would definitely recommend. Look for deal with tubes. Save a few bucks

Best one I've purchased!
I recently purchased this tire for my e-bike, and I have to say, I’m extremely impressed with the overall quality. The material used feels very durable and premium, and the rubber has a really solid texture to it. One of the first things I noticed was the excellent grip—it gives a strong sense of control and stability while riding, even on slightly uneven or wet surfaces. The design is also appealing. The logo on the side adds a stylish touch, which makes the tire look even better once it’s mounted. After switching to this tire, I noticed a huge improvement in the comfort of my rides. The bumps and small vibrations I used to feel are now significantly reduced, and I feel a lot more confident while cruising around. It handles corners smoothly, and the traction is just perfect for city streets as well as light trails. Honestly, out of all the tires I’ve used before, this one stands out as the best. The build quality is simply superb, and I feel like it will last a long time. If you’re looking to upgrade your e-bike tires, I would definitely recommend giving this one a try. Totally worth the price!

Stiff tire
Why did you pick this product vs others?: Absolutely love these tires. Exactly what i was looking for. These are not some floppy thin foldable tires. These are nice thick tires. The tread is meaty and seems like they will be excatly what i need for my drift trike. The tread is directional so make sure to put them on the right direction. I used a 26x3.5 tube in mine so they wouldn't balloon out when filled up to max psi. And its working out better then expected. My rim is 83mm wide. The tire will definitely fit a 100 mm rim if needed. I just installed them will use them a while and if durability or any issues arrive ill update the review. As of now im very happy with this purchase Fit: is perfect for my rim. Its about 83-85mm which this tire could do wider if needed. Weight: Tire has nice weight to it definitely heavy tires compared to foldable flimsy tires. Value for money: For the price i cant complain to much their are worse tires for way more money Traction: tread is deeper then the pics in listing lead them to look. Id say almost half inch deep treads. At max pressure they do have a more rounded top which is nice on flat smothe ground allows it to roll better. Then droping the psi to a lower pressure allows them to flatten out a bit for more traction. My use is the front tire on my drift trike so ill never see any trail riding to comment on. Performance: Like i said mine are my DTG drift trike front tire. With the stock rim. Ill be going out and putting them to a real hard test ride today. Will update if they perform crapy. They seem like their going to be a great tire.
