Rim tape needs to the correct type and size to fit the rim snugly so it doesn’t slip when replacing a tube or mounting a tire.
Do bike tubes expire?
Heat and UV light are very bad for latex, so where the tubes were stored could be a big factor. Latex tubes deteriorate only if outside and exposed to light, sun, UV and extreme temperatures. There are tubulars that are 20 years old and still run great, so the tube has a long life when protected.

What is bike tire bead?
Tire bead is the term for the edge of a tire that sits on the wheel. Wheels for automobiles, bicycles, etc. are made with a small slot or groove into which the tire bead sits. When the tire is properly inflated, the air pressure within the tire keeps the bead in this groove.
Do all bikes have inner tubes?
Most bicycles today have tires with tubes inside. The tube is made of rubber, has a valve in it for inflation, and is just the right size and shape to fit inside the tire. When you inflate most tires, you are actually pumping air into the tube inside the tire, which fills the tire.

For example, one of our most popular tubes is the 26 x 1.75-2.125” which means it fits a 26-inch diameter tire with a width in the range of 1.75 to 2.125 inches.
