What is the difference between 265 50R20 and 265 60R20?
Your standard tire, 265/50R20 is approx. R20 is approx. This percentage compares the tire’s section height with the tire’s section width. For example, this aspect ratio of 60 means that the tire’s section height is 60% of the tire’s section width. R indicates the construction used within the tires casing.Typically, low profile tyres have an aspect ratio of 50 or lower. This means that the height of the tyre’s sidewall is only half or less than the width of the tyre.Taking the example of 275/30 R20 97Y, the number 275 indicates the tyre width in millimeters; 30 is the aspect ratio, the height-to-width ratio expressed as a percentage (30%); R stands for radial and specifies the construction of the carcass; and 20 is the rim diameter in inches.
