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.

Shipping, packing, everything you need is included and packaged very well to avoid warping. QR with full instructions if needed. Easiest and cheapest way to change the way your vehicle rides, and worth every penny. Quality of construction is very evident right out of the box, and the provided tools are useful keepers for sure. These are not some thinwall flat prone bouncy tire, these are serious about their job.

Ultraverse tires shipped in a box to accommodate the full size of the tires. The tires are about 2 pounds heavier than my stock tires. Quality construction with very durable side walls. I paired the tires with a set of Ultraverse inner tubes. The installation was straightforward, with no issues. Once mounted, the tires were free of balance problems or warping.

Useless tire. They advertise this would not puncture from hard sharp items yet a small little piece of broken glass ripped into my tire the first five minutes riding with these tire. They are heavy and waste more battery power on my e-bike. They were extremely difficult to put on and take off. The fact that they easily went flat really bothers me. It’s advertised to be better than my standard tires but I can last longer than what these tires did. I tried to return the tire but got too busy and missed the return date. So I’m out of a lot of money and stuck with no good tires.

Great tire. Just as good as the Kendra on my other bike. Great sidewall strength. Thick tread area to help prevent small punctures. Built more like a car tire.

Badass. These tires should outlast the coming apocalypse. Big improvement over OE (small, heavy ebike). Noticeably quieter, nicer ride.
