A fibroblast is a type of cell that synthesizes the extracellular matrix and collagen,[1] the structural framework (stroma) for animal tissues, and plays a critical role in wound healing. Fibroblasts are the most common cells of connective tissue in animals.
For example, a 700 x 20 C road tire would be a 20-622; a 700 x 38 hybrid tire would be a 38-622. The width difference between these sizes would make them less-than ideal replacements for one another, but any rim that could fit one of them would work after a fashion with the other.
Find the numbers that represent the size of your ATV tire on the side of the tire. You should see three numbers, separated by X's dashes or a combination of both. Read the first number. That number represents the diameter of your tire. For example, if the numbers say, 26X10-12, the diameter of the tire is 26 inches. Another way to think of this measurement is the height or how tall a tire measures.
