Alternate Tire Sizes

Use the tire figurer to populate a listing of alternate tire sizes.

Click on each size to see bachelor tires in that size.

Use our tire size calculator to calculate the diameter, width, sidewall, circumference, and revolutions per mile of whatsoever tire. Just type in a metric or standard size tire and click calculate.

Inch measurement tires are fairly piece of cake to understand however metric tires use a more difficult organisation to read. The first number on a metric tire is the width in millimeters. Divide this number by 25.4 to get the inch equivalent as there is 25.4 mm in i inch. The tertiary number more often than not preceded by an "R" is the wheel bore. The sidewall or aspect ratio are used in metric tire sizes to determine the overall height of a tire. The 2nd number on a metric tire is to calculate the side wall measurement. The sidewall elevation is a pct of the width of the tire. This 2d number is that percent. The sidewall peak or "attribute ratio" of a 285/75/R16 tire is 75% of 285mm.

To calculate the diameter of a metric tire in inches: (#ane ten #2 / 2540 x 2) + (#3)

Case: 285/75R16 (285 X 75 / 2540 x ii) + sixteen = 32.8 inches tall.

Our tire calculator makes this happen for you. Just blazon in any tire size and click calculate. Information technology as well solves the problem of deciding what tire you would like to run if yous have inch tire measurement in mind just can't detect a company that manufactures that inch tire size. Merely fill in the inch measurements you are looking for and it will populate suggested tire sizes that are with in i inch bigger and smaller of the entered inch tire size. There are more possibilities and choices in metric tires and then the use of a tire size figurer can be very useful.

The tire size comparison calculator takes the measurements of two tires and compares the diameter, width, sidewall, circumference, and revolutions per mile. Then as a bonus it shows examples of your speedometer reading with the showtime tire, and the actual speed y'all're traveling if you were to install the second tire. A very useful tire calculator when searching for tires that are a different size than stock.

Some other tire size computer we have is our speedometer correction figurer. This is valuable if y'all plan to or are already running bigger tires than stock, and want to know the speed yous are actually traveling compared to you lot're speedometer reading. A bigger tire has a larger circumference, thus traveling a further distance for each revolution. A speedometer reads the amount of revolutions your tires are making, not how far y'all are traveling. Therefore you lot are actually traveling faster than your speedometer says when you lot have larger tires than stock, and slower than you're speedometer says if you have smaller tires.

Our like shooting fish in a barrel to use tire diameter calculators volition always be useful at ane time or another. A tire size conversion calculator or tire bore calculator is the best style to get the answers y'all are looking for when it comes to tire sizes. What sets united states of america apart is our tire proposition guide. For each tire size y'all input our tire calculator suggests multiple tire sizes that are with in one inch bigger and smaller of the entered tire size. Select each link to see a list of tires that are manufactured in that size.
