    • Rolling confidence...great tires.
Size: 20x4.0 Style: 2 Unit Pack
The 2-pack of these tires arrived quickly in a box 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 ones but didn't need them. Still, the included rim protectors are a nice touch. Overall, great tires, great purchase experience, I'll buy again when these wear down. ... show more

    • Awesome tires
Size: 20x4.0 Style: 2 Unit Pack
Fantastic tires, smooth ride, and very quiet. So much better than the stock tires that came with my e-bike. Hugh upgrade, can feel the difference right away. I ride mostly, pavement, these are for the road. And they are nailing it!!! Little finicky getting them on. Trick, watch the marks, and a spray bottle with a little soapy water. I also, installed heavy duty tubes, and flatout! So hopefully no more flat tires! ... show more

    • Premium tires just a little too stiff and hard to balance.
Size: 20x4.0 Style: 2 Unit Pack
These are good tires and feel that you get the value you pay for it is they are just too hard to balance and get wobble out of. I kept the front one on but had to replace the back tires as it was causing issues. They are also hard to install, relatively.

    • Silent, Fast, Safe, Durable, and Stylish!!!
Size: 20x4.0 Style: 2 Unit Pack
Couldn't ask for a more solid design. My ebike runs 50mph and I needed tires I could trust and went through the cheaper brands before I found these. I'll be a lifelong customer now!!! Side walls are solid, tread is silent and sticks to the road like they should, water isn't an issue, and I'm getting more top speed and battery life with these. Well worth the money, don't waste time trying other brands like HEB and Allscape and that's coming from an avid everyday rider!!! You get what you pay for and these tires are worth every penny!!! If you're looking for safety, silence, grip, durability, less resistance, more battery life, and more top speed on your Ebike you found it in these tires!!! ... show more

The package came crushed and the tire didn't seat. took it to a bike repair shop and they said there was an issue with the tire itself, and that they couldn't do anything about it.
