no problems so far

July: (Have now had the new one on for over 2 months now and are still doing good. Am getting reviewing.

So far so good!

Purchased to replace my CST BFT on my Kepler. Mounted with no issues and ride is soft and smooth. Only 50 miles on it so I can't attest to the long term durability. I like that it's 30 TPI and has solid black sidewalls. Decent overall fat tire for $40 price range.

Love the new pattern

My electric bike have fat tires and if they need to be replaced this is what I use. This is the same size as the tires my bikes came with and it’s not difficult to install it. It functions as expected and I haven’t had any issues using it.

Excellent tires for both street and trails...

Perfect riding tires on the street and dirt trails or grass... Replaced my Hycline 20” fat tires and tubes. I did it myself and I’m no mechanic! I’ve put about 100 miles on them. No problems!

Good budget tire

For under 40 dollars it is worth it. The original front tire on my 0ver 3 year old ecotric is still on the bike so even they last longer. So after reshaping the tire by bending the kinks out of the bead and wrapping a rope around the circumference and inserting a screwdriver and twisting to compress it overnight it installed without a problem. I had no issue with the bead popping but I only inflate to 20 PSI . After the tire settles in after a couple weeks I install my home made tire liner cut from the worn flat center 3 rows of the old tire. If you cut it to 90.5 inches and tape seam with gorilla tape it works great no issues.

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.

Can I buy just one tire? Or match my bike with different size/tread tires?

Yes! it is able to buy just one tire for your bike. However, it's generally recommended to replace both tires at the same time to keep consistent performance and riding experience. 
Regarding matching your bike with different size or grain tires, it is important to ensure that the new tire is compatible with your bike's rim size and frame clearance. You should also consider the impact on the handling and performance of your bike, as different tire sizes and tread patterns can affect the way your bike handles, especially when cornering and braking.
