Wheel to the suspension. For example imagine your tire says P27555R20.
Youre tire will actually give the diameter of the rim.
How to determine tire size for rims. The sidewall height or aspect ratio of a 28575R16 tire is 75 of 285mm. To calculate the diameter of a metric tire in inches. 1 x 2 2540 x 2 3 Example.
28575R16 285 X 75 2540 x 2 16 328 inches tall. Our tire calculator makes this happen for you. Just type in any tire size and click calculate.

While many people refer to wheels as rims this is technically incorrect. Wheels come in all different styles sizes bolt patterns and offsets. For example appropriate tire widths for 60 rim are.
175 mm 185 mm 195 mm and 205 mm. The minimum tire width 175 mm designates the safe tire width 185mm and 195 mm are ideal tire widths and 205 mm is the maximum tire width. The maximum tire width is not ideal because the tire tread is wider than the inside rim bead.
Subtract the center of the rim from the backspacing to find your offset. For example lets say you have a rim with a 9 in 23 cm width. The center of the rim must be 45 inches 11 cm.
Offset and backspacing will help you determine brake clearance on a rim. Measure a brake disc from edge to. To compare tire sizes first select your vehicle stock tire size.
Immediately available tire sizes that are with in plus or minus 3 variance will be displayed. Select the tire sizes to compare to your stock size and click Compare Selected Sizes. Into the form below select the tyre size and click on the button Find Rim Size.
The table containing the recommended wheelrim sizes for the selected tyre dimension will be presented below the calculator. We strive to help you get the information you need about PCD offset rims and all other wheel and tire data that you need for your vehicle. This guide is accurate and is updated on a daily basis.
Youre tire will actually give the diameter of the rim. For example imagine your tire says P27555R20. That R20 at the end actually indicates that this tire is for a 20 diameter wheel.
The section height is then determined by multiplying 886 inches by 040 forty percent. 886 x 040 354 inches. Find the series of numbers on the sidewall.

Tire section width is used to most accurately determine the size designation of a tire. Also commonly referred to as casing width section width is expressed as the first two digits in the ETRTO size designation XX XXX marked on the sidewall of every WTB tire. WHAT IS YOUR RIM SIZE.
ETRTO RIM SIZE DESIGNATION. Rims are measured in diameter and width according to the tires they fit. Tires are measured by section width section height or profile rim diameter and tread width.
Tread width merely notes the spread of a tires tread as it meets the road and doesnt factor into rim size. The last thing on the form is a current wheel and tire size. To find the backspacing of our current rims we clamped two squares together and then used a third to measure our backspacing.
The tire size determines the range of rim widths that are safe to use. For example a tire size 24545R-20 has a rim width range of 75 to 95. This means that this tire size would fit a rim size of.
