So let me get this right
If the width of the tire is written as 9.00 or 9 then the height of the tire is also the same as the width?, ie a 100% aspect ratio.
While if its written as 12.5, 14.5 etc then the height of the tire is 80% of its width thus the 80% aspect ratio?
And sorry if I am asking a lot, I'm just trying to understand that off way of figuring out tiresizes
Just found this, please let me know if its is actual correct or not:
3 or 4 digit number: The section width (cross section) of the tire in inches. If the tire diameter is not given, section widths ending in zero (e.g., 7.00 or 10.50) indicate the aspect ratio is 92%, while section widths not ending in zero (e.g., 7.05 or 10.55) indicate the aspect ratio is 82%.
As an example, if a tire size has two sets of numbers (6-12, 5.00-15, 11.2-24) the first number (5.00-15) is the approximate width in inches; the second number (5.00-15) is the rim diameter in inches.
If a tire size has three sets of numbers (15x6.00-6, 26x12.00-12, 31x15.50-15) the first number (26x12.00-12) is the approximate height in inches, the second number (26x12.00-12) is the approximate width in inches, and the third number (26x12.00-12) is the rim diameter in inches
Thanks in advance and thanks for the help
