How to Properly Calculate Tire Sizes

Often it it is cost efficient to exchange your original tires for a different size.
For lots of drivers changing sizes can be confusing because they do not know how sizes compare.

We will set straight how switching sizes relate to other sizes.

Tire Numbers:
The first numbers of a tire's size illustrates the tire's section width. This is the space between what you see from the outside side wall to the inner side wall (the opposite side of the tire you can not see under the car).

The second group of digits illustrates the aspect ratio. This is the percent of the sidewall's height in comparison to the section width. Simply the length of the tire's length from the wheel compared to the inside width. One may consider it similar to a container with different height, depth and width distances to think about it easier.
The 3rd set of digits show the size of the rims in inches.

Tire Sizing Comparisons
Right away it is crucial|vital|critical} that we mention that the size of the tires should be within 3 percent of each other as a rule.
The most common way to compare and contrast sizes is to obtain the complete diameter of the tire and compare it with the replacement tire.
To get the diameter of both tires we must obtain the sidewall height. To get this multiply the section width by the aspect ratio or profile percent and double it. For example: 195*.45*2= 175.5.

Subsequently convert the rim size from inches (multiply by 25.4) to get millimeters and sum it with the previous equation.

After that just divide the replacement values by the current tire numbers - then all you needs to do is minus one from it - and multiply by one-hundred. This will let somebody see the percentage size change between the new tire and initial tire.

Bear in mind that the standard potential tire needs to be within three percent bigger or smaller and you should always verify the possible replacement tire with the potential manufacturer for errors.
