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.
For example, appropriate tire widths for 6.0 rim are: 175 mm, 185 mm, 195 mm and 205 mm. The minimum tire width 175 mm designates the safe tire width, 185mm and 195 mm are ideal tire widths and 205 mm is the maximum tire width.ire widths for a wheel/rim size chart shows what tire widths fit displayed wheel/rim sizes-shows tire width range for a given rim width: minimum, ideal and maximum tire widths (e.g. for an 7 wheel/rim, following tire widths can be fitted: 195, 205, 215 or 225).
