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.
HOW TO READ YOUR TIRE SIZEâ¦ If your tire size has two sets of numbers (6-12, 5.00-15, 11.2-24â¦) the first number (5.00-15) is the approximate width in inches; the second number (5.00-15) is the rim diameter.
