Is 195/65 R15 a standard tire size?
The tire size 195/65R15 is a common size used on many trucks, SUVs, and other larger vehicles. Imagine the rim as a well. The rim diameter is the width of that well, measured from bead seat to bead seat—the spots where your tires grip the rim. This measurement is critical and must correspond exactly to the diameter of the tire being mounted. For example, a 16-inch tire must be paired with a 16-inch rim.What do rim size numbers mean? This number represents the distance between the two bead seat areas where the tire is sealed onto the wheel. The wheel size also includes its width and offset. The width is the distance from each bead seat (from inside to the outside).Look at the numbering on the tires. Example, 275 /65/ 18 means 18 rims. It’s the last numbers in that set. You can look on the inner door on the driver’s side, and there should be a sticker saying what size tires you should have on.
What does 195 65R15 mean on tires?
P195/65R15 The first number tells the tread width, in millimeters. It usually ranges from 155 to 245. The second number indicates the height of the sidewall; it is a percentage of the tread width. Mostly between 80 and 45. The letter R means that the tire is a radial. These numbers show the aspect ratio, which is the tire sidewall height in percentage to width of the tire. The width of Sidewall is directly proportional to the aspect ratio, a 70 aspect ratio means the sidewall height is 70% of 265mm while 65 aspect ratio means it is 65% of 265mm.This is also known as the aspect ratio. The lower the number, the more ‘low-profile’ the tyre.In this case, the aspect ratio is 80, meaning that the height of the sidewall is 80% of the tire’s width. Tyre type and wheel diameter R13: The R stands for Radial, indicating that the tire has a radial construction.
What does d or r mean on tires?
After the aspect ratio, there will generally be a letter – either R, D, or B. This refers to the internal construction of the tire. R stands for radial, the industry standard for most passenger vehicles today. D means diagonal construction, while B signifies belted bias construction. These numbers show the aspect ratio, which is the tire sidewall height in percentage to width of the tire. The width of Sidewall is directly proportional to the aspect ratio, a 70 aspect ratio means the sidewall height is 70% of 265mm while 65 aspect ratio means it is 65% of 265mm.
