It's for vehicles with 21-inch wheels and tire widths from 2.75 to 3.00 inches. Check your old inner tube's size to replace it correctly
High-quality Material: Each 2.75/3.00-21 inner tube has 45% more rubber. It can stretch 4.8 times, and its sidewall is thicker, so it resists punctures. The soft inner tube absorbs vibrations well, making your ride more comfortable. The butyl rubber inner tube can hold air for up to 6 months
TR4 Straight Valve Stem: The valve stem seals well. It stops dust and sand from getting into the inner tube and tire. The rubber valve seat is strong and hard to tear. This helps the valve last longer
Installation Tips: Check if the inner tube leaks before use. If it does, leave a message and send pictures and info. We'll fix it fast. Clean the inside of the outer tire before installing to stop it from puncturing the inner tube. First, put a little air in the inner tube. Then put it in the outer tire and fill it up more. This makes it fit the tire wall better
