Great quiet tire!

Easy to install and set bead on rim with little dish soap. Good tread and quality made tire. Highly recommend these tires. It's worth the extra money. Super smooth ride!Buy these you won't be disappointed.

Much more quiet than knobbies

Replaced the knobbies on my ebike with these... The ride is a lot more quiet on pavement, and I feel I'm getting a few more miles out of them per charge. Still has enough grip for light trails and gravel, but I wouldn't take them out on rough trails or sand. I can't speak to the longevity of the tires, as I just installed them. Thus far I'm happy with them.

Smooth, quiet ride

Easy to install, fits well on my magicycle cruiser pro. Much quieter then the original snobby tire that came with the bike. Good tread thickness and not a heavy tire. My range has improved around 10% with the new tires. Good grip on dry pavement, have not had it on wet pavement yet but the tread design seems like it will work fine. 120 miles on new tires. Very happy.

Really good tire!

I ordered this tire for my ebike. I was needing a replacement for my rear tire. This tire is a very good replacement. It appears to be a good quality item. I like the tread pattern that works well for my road riding and the occasional ride off road. I have used other Hycline tires and they have worked well. This is a good product.

What should I consider when choosing bicycle tires?

When selecting bicycle tires, consider the size, tread, width, durability, pressure, weight, and riding style. Choose a tire that fits your bike's wheels, is appropriate for the terrain you'll be riding on, is durable and puncture-resistant, can handle the recommended tire pressure, and matches your riding style.

What size bike tire do I need for my bike?

To determine the size of tire you need for your bike, you can look at the sidewall of your current wheel, which will have the tire size printed on it. The size will typically be expressed as a combination of numbers and letters, such as "700x23c" or "26x2.0". The first number refers to the diameter of the tire, which is measured in millimeters for metric sizes (e.g. 700) or inches for imperial sizes (e.g. 26). The second number refers to the width of the tire, also measured in millimeters or inches. The letter at the end indicates the type of tire (e.g. "c" for clincher)
If you're unsure about what size tires to get or have any doubts about compatibility, you can consult your bike's owner's manual or contact the manufacturer for advice.
