The second number the 90 represents how tall a motorcycle tire is in relationship to its width. In simple terms this means the larger this number is the taller the tyre will be.
The series number in a tire-numbering system refers to the aspect ratio of the tires sidewall height to its width.
What does the aspect ratio of a tire mean. A tires aspect ratio determines the height of the sidewall which ultimately determines the overall diameter of the tire. The aspect ratio is a percentage of the section width. The aspect ratio is not easily identifiable but its there - literally it is a ratio that compares the width of a tire to the sidewall height.
Learn more about tire aspect ratio and other important tire information. Aspect Ratio Is the ratio of the height of the tires cross-section to its width. The two-digit number after the slash mark in a tire size is the aspect ratio.
Tyre aspect ratio explained The side wall code lets you know the tyre specs such as width load index diameter speed rating and profile of a particular tyre. In the example below the aspect ratio of the tire is 70 percent so the section height of tire will be 1295mm. The higher the aspect ratio the taller the tire sidewall.
Its the height of the sidewall measured from wheel rim to top of the tread expressed as a percentage of tire width. In other words its sidewall height divided by tire width. Calculating Approximate Tire Dimensions Tire Rack pair of numbers 225 45R17 is the tires aspect ratio or profile.
This percentage represents the ratio of the sidewalls section height to the tires section width. Aspect Ratio This is the ratio of the height of the tires cross-section to its width. 21745R17 246 overall diameter 773 circumference.
21765R17 280 overall diameter 879 circumference. The aspect ratio is a tires section height as compared to its section width. The aspect ratio is often referred to as the tires series With that in mind a 50-series tire has a section height that is 50-percent of the section width.
The tire size shown above is P18560R14. The 185 represents its section width. The number 60 indicates the tires aspect ratio.
The last number 14 indicates wheel diameter. Tire Section Width The tire numbers in the above example tell us that the tire is 185 millimeters wide. The first number in this series refers to the tires section.
The aspect ratio is the tires profile. For instance a tire with a 60 aspect ratio means that the tires hight from tread to rim is 60 of the tires nominal width. The lower the aspect ratio the.
Aspect Ratio You use the aspect ratio to indicate a tires cross-sectional profile. A smaller number means a lower profile and the height-to-width ratio is shown as a percent. For example if the aspect ratio is 90 that means that your tires cross-sectional height is 90 of its width.
Calculating Approximate Tire Dimensions Tire Rack pair of numbers 225 45R17 is the tires aspect ratio or profile. This percentage represents the ratio of the sidewalls section height to the tires section width. The series number in a tire-numbering system refers to the aspect ratio of the tires sidewall height to its width.
A series 65 tires height is 65 percent of its width a series 70 tires height is 70 percent of its width and so on. These differences in height affect both performance and safety issues while driving. R is for radial and 225 is the wheel diameter measured in inches.
The aspect ratio by default is about 90 which means that the tire sidewall width is 90 the width of the tread. In low profile sizes such as the 29575R225 295 is the tread width measured in mms and 75 is the aspect ratio. The second number the 90 represents how tall a motorcycle tire is in relationship to its width.
This is the aspect ratio between the tires width and its height indicated as a percentage. In simple terms this means the larger this number is the taller the tyre will be.
