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.
An LT designation is for a light truck. Tire width is the width of the tire measured in mm from sidewall to sidewall. This tire width is 215 mm. Rim diameter is the width in inches or cm of the wheel from one end to the other.The diameter of this wheel is 16 in. Always replace a tire on a rim with another tire of exactly the same rim diameter designation and suffix letters. Speed rating tells you the maximum service speed for a tire.A speed rating isn't, however, a recommendation to exceed speed limits, and doesn't indicate how well a tire handles or corners.n LT designation is for a light truck.
