Generally, very good fast durable tires
Best tires I’ve ever had. They are hard to get on and then instruction videos, kind of crap compared to the way I got them on which was a little easier. Just one part at a time with the tube already inside of it works better. They’re streamline and a lot lighter than my ones before and very puncture resistant. I’m 510 150 pounds on a 26 inch bike and I have no death wobbles. My brother who however is over 200 pounds did have some so I just want to put that out there. I think we had a big weight difference. But for me, it eliminated all death wobbles. I run them at 40psi which I feel isn peak performance for them. Definitely worth the buy, for me. ... show more

Ultraverse 20X4 Tires - First E-Bike Upgrade - Fantastic
Size: 20x4.0 Set name: Set of 2 UNITS
Amazing tires. Great value for the money. Swapped out the offroad knobby tires that came with my e-bike for these and the difference in vibration and sound levels is night and day. These babies really grip the road, very sure footed on pavement and tight dirt roads. They came with the tire irons and the Ultraverse Rim Protectors - a very nice touch! They provided really detailed installation and troubleshooting videos. I didn't need to use tire irons to mount them and the side wall markings showing the correct rim insertion depth made them go on the first time - no wobbles or hops. Highly recommend! ... show more

The 2-pack of these tires arrived quickly in a box (not folded) with the tires strapped together with bright yellow velcro straps with the Ultraverse logo. Not tie wrapped together, velcro straps. Included were two large metal tire irons and a couple yellow rim protectors (looks like they read the comments). These tire are sturdy; important on an electric moped. A bit heavier and more expensive than some others but everything about these tires inspires confidence. The build quality, steel beads, puncture resistance, strong sidewalls, smooth center strip with heavier side tread for softer surfaces all make me comfortable riding with the tires inflated to the max 30psi rating. The included metal tire irons seem like overkill for these tires, I got the tires on just by pushing on the sidewalls. I would have used some old reliable Specialized plastic tire tools but didn't need them. Still, the included rim protectors are a nice touch and responsive to user comments. I've been riding on these for several months and still very satisfied with the purchase. Lots of miles and (KOW) no issues. Tires are sturdy, roll well, hold air pressure, look great and consistently get positive comments from other riders. Overall, great tires, great purchase experience, worth every penny. I'll buy again when these wear down. ... show more

Quality that matters
Love the tires! Read previous reviews and I'm not sure where some of these riders were riding but I have experienced no issues. One of the things i enjoy most about the arrival conditions was the size of the box to protect the product, the tires are quality and to see a company take an interest in protecting the tires was a plus for me. Pros: More robust, quieter, ride smooth and grip tight. Cons: Getting the tire fit on the rim was a challenge, and slowly having to apply air to the tire is a bit of an art to make sure the seam of the tire are inside the rim. The cons is nothing against the quality of the product, its more the installer of the tire. I would recommend this product and purchase against when needed. ... show more

Impossible to install yourself. Requires $100 bike shop visit.
Size: 20x3.0 Set name: Set of 2 UNITS

Horrible sizing, cannot get the tires onto the wheels. Popped two tubes trying to manhandle these things onto my sons e-bike wheels. The tires are exactly the same size as the last ones he had on there but I cannot for the life of me get these mounted on the wheels. I have tried warming them with a heat gun, lubing them with petroleum jelly, and leaving them in the sun to warm up. But they still appear to be more than an inch too small in diameter and every time I try to use the include tire levers and tim protectors, it catches on the inner tube and pops it. I've destroyed two tubes trying to install one tire. I'm going to have to give up and try to take it to a bike shop now. I've been repairing my bike and my kids' bikes and replacing tires for over 25 years and I've never had this much trouble before ever. While the quality of the tire is excellent, the thickness hinders the ability to install these yourself. I would not recommend these in the 20x3.0 size. ... show more

you won't be disappointed
I put these on a 2026 Wired Freedom. Great improvement to my ebike as now it handles like it's on rails, has an even better ride, brakes better and 10 times quieter than the knobbies that it came with! You'll love the way your bike rides with these babies!!!
