How can I read the tire size of the car?

215: The total width of the tire when the tire is raised, relative to the surface that touches the floor.
45 : The height of the tyre. Subtract the diameter of the inner rim from the diameter of the outer circle of the tire and divide by 1/2.
R: Redial construction.
17 : The diameter of the rim (Rim, the inner diameter part of the tire equal to the size of the wheel).
