It depends on what you mean by width. If you view the wheel as a disk and consider its width as the side-to-side measure, then they two are the same so the ratio is 1.
If you view the wheel head-on and consider its width as the profile, then there is no relation.
These are not similar rectangles so there is no obvious candidate for the ratio. Is it ratio of lengths (sides, perimeter, diameter), or ratio of area?
This is a measure of a car tyre. It is a combination of units and ratios that is enough to drive most people nuts! 175 refers to the width of the tyre (in millimetres) from sidewall to sidewall. 15 refers to the diameter of the wheel rim (in inches). 75 is the ratio (in percent) of the profile to the width. The profile is the length from the wheel rim to the edge of the tyre. I suspect the r means a radial tread but I am not sure about that.
Diameter is the width of a circular or spherical figure or object. Something 180 inches in diameter is also 180 inches in width or thickness.
ratio of circumference to diameter of a circle is 3.14159265:1
Oh, dude, it's like super simple. So, the diameter of a circle is just the distance across it, right? And the width is just the distance from one side to the other. So, to convert diameter into width, you just divide the diameter by pi. Easy peasy!
velocity ratio= 2D/(d1 - d2) , where D = diameter of effort wheel,d1&d2= diameter of the axles.
Wheel size is composed of 2 dimensions, the wheel width and wheel diameter. For example, a 22×9.0 wheel has a diameter of 22" and a width of 9". You can also check the wheel size by looking at the vehicle owner's manual or by looking at your tire TIN number.
G - Load/Size R - Radial Design 78 - Hieght/width ratio 15 - Rim/Wheel Diameter in Inches
Width x Aspect Ratio = Section HeightSection Height x 2 = Combined Section HeightCombined Section Height + Wheel Diameter = Tire DiameterExample: 185/60R14 85H or 185/60HR14185mm x .60=111mm111mm x 2=222mm222mm + 355.6mm(14")= 577.6mm or 22.74"The first number is the width of the tire in millimeters, measured from sidewall to sidewall. To convert to inches, divide by 25.4 In the example above, the width is 185mm or 7.28".The second number is the aspect ratio. This is a ratio of sidewall height to width. In the example above, the tire is 7.28" wide, multiply that by the aspect ratio to find the height of one sidewall. In this case, 185x0.60=111mm or 7.28"x0.60=4.36".The last number is the diameter of the wheel in inches.To figure the outside diameter of a tire, take the sidewall height and multiply by 2,(remember that the diameter is made up of 2 sidewalls, the one above the wheel, and the one below the wheel) and add the diameter of the wheel to get your answer.255/25.4=10.03937 that's up to you now..
The recommended tire size for a bike with a 26-inch wheel diameter and a width of 2.125 inches is typically 26 x 2.1.
The recommended tire size for a bicycle with a wheel diameter of 29x2.25 inches is typically 29 inches in diameter and 2.25 inches in width.

The recommended tire size for a bike with a 26-inch wheel diameter and 3.5-inch width is typically 26 x 3.0 inches.
A 700c wheel typically has a diameter of about 622 millimeters and a width of around 23-28 millimeters.
265 = Width of tire in Millimetres 40 = Ratio of height to width (aspect ratio) Z = Speed rating for over 150Mph (240Kph) R = Radial - the construction of the tire 18 = Diameter in inches of the wheel the tire is designed to fit. In summary, this tire is for a sports car with 18 inch wheels.
20 inches measured where on the wheel? Radius? Diameter? Circumference? Width?
The recommended tire size for a bicycle with a 27-inch wheel diameter and 1.25-inch width is typically 27 x 1 1/4 inches.
