P20555R16

P20555R16 refers to a specific tire size designation. The first number, 205, indicates the tire's width in millimeters across its sidewalls. The second number, 55, represents the aspect ratio, which is the height of the tire's sidewall as a percentage of its width. In this case, the sidewall height is 55% of 205 millimeters. The letter R signifies that the tire is of radial construction, meaning its internal structure has cords running radially across the tire. Finally, the number 16 denotes the diameter of the wheel rim in inches that the tire is designed to fit. This tire size is commonly found on a variety of passenger vehicles, including sedans and coupes. When selecting replacement tires, it is crucial to match the original tire size specification to ensure proper fitment and optimal performance of the vehicle. This information is typically found on the tire's sidewall itself, as well as in the vehicle's owner's manual or on a sticker located on the driver's side doorjamb.
