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?
To convert the tire size 275/65R18 into inches, you can break it down: the first number (275) represents the width of the tire in millimeters, the second number (65) is the aspect ratio (the height of the sidewall as a percentage of the width), and the last number (18) is the diameter of the wheel in inches. The sidewall height can be calculated as 65% of 275 mm, which is approximately 178.75 mm, or about 7.03 inches. Adding the sidewall height twice (for both sides) to the wheel diameter gives you the overall diameter of the tire, which is approximately 31.03 inches.
The APT (anterior-posterior to transverse) diameter ratio of the thoracic cage is measured by comparing the anteroposterior (AP) diameter to the transverse (width) diameter of the chest. This is typically done using imaging techniques like chest X-rays or CT scans, where the AP diameter is measured from the sternum to the spine, and the transverse diameter is measured at the widest part of the thorax. The ratio is then calculated by dividing the AP diameter by the transverse diameter to assess the shape and potential abnormalities of the thoracic cage.
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.
The diameter of a P225/75R15 tire can be calculated using the formula: Diameter = (Aspect Ratio × Section Width × 2) / 100 + Wheel Diameter. For a P225/75R15 tire, the section width is 225 mm, the aspect ratio is 75, and the wheel diameter is 15 inches. This results in a total diameter of approximately 27.0 inches (or about 685 mm).
A 265/70R17 tire has an overall diameter of approximately 31.6 inches. This measurement is derived from the tire's width (265 mm), aspect ratio (70%), and wheel diameter (17 inches). To convert the dimensions, you can use the formula: Diameter = (Tire Width * Aspect Ratio * 2 / 25.4) + Wheel Diameter.
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
The tire size 245-45-17 indicates the tire's width, aspect ratio, and diameter. The first number, 245, represents the tire's width in millimeters. The second number, 45, is the aspect ratio, which shows that the height of the tire's sidewall is 45% of the width. The final number, 17, indicates the diameter of the wheel rim in inches that the tire is designed to fit.
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..
