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.

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!

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.

These tires are absolutely horrible do not waste your money. I spent $140 on two tires. I could have bought 8 of the cheap Chinese whatever ones that would have lasted 10 times longer for the same price . One of the tires the belts in the bead literally came out and popped the tube within 10 Mi of installation however it had taken me a while to actually put them on my bike so I was past the return date by the time this happened. Now I'm out $69.99 plus shipping for nothing. And to top all of that off the tires are extremely heavy which caused my bike to slow down significantly and I'm running dual motors with a 52 volt battery 3000 watt front hub motor and 1500 watt rear

These are the most durable tires ive got so far. I've been through around 5 sets of tires for my 72v 5000w ebike commuting 20+ miles a day to and from work. In the rain/shine/heat/ice and these are AWESOME in any weather so far. Also most fat tire ebike tires are not the best puncture resistance as i would have a flat around every two weeks at the lease. I've had these for 4 months and not a single flat whatsoever. I will ONLY be getting these and I still have around 95% left on these bad boys. They look great. Only bad thing is the white letters turned a shade of tan now.

Nice quality tire. Much better than the cheap thin stock one. Lots of meat on it.

These are the most god awful tires to install and seat, I couldn't even rotate them from the front to the back because it is physically impossible to install this tire without breaking your fingers. Couldn't even get them on with soapy water or a tire lever. Everything else about them doesn't even justify buying them. Don't buy these unless you want to piss you or your bike shop off. EDIT: I got with support and they gave me a different set of tires, along with plastic rim protectors to help the tire levers from chipping the rim's paint. When you put the whole rim and wheel in your lap, it is a lot easier to install the tire, but with these, it is still on the difficult side. If you deal with Ultraverse's support, they are very helpful when it comes to solving any problems. They are great road tires when you get them on.
