Rim and tire widths are an important element when installing new tires on the aluminum or steel wheels for the car.
Most normal people may find it difficult to see how the width of a tire or rim is read, as well as how to choose the correct tire width for one's rim.
The width of the tire is read on the tire side and is always followed by the profile. The width of the tire is written in millimeters and is thus written on the outside width / profile / radius of the tire
Example of tire width written on tire side: 185/55-R15
In the above example, the tire width is 185 mm, the profile is 55% of the 185mm and the radius of the tire fits a 15" rim.
On the rim, the width is read around the back, they are written in inches followed by a j. An example of a 6.5" wide rim will be written as 6.5j around the back of the rim.
Once you have read your rim width you can now select the width of your new tire. Here in the table you can see the minimum tire width, the recommended tire width and maximum tire width.

If you want to measure the rim width yourself:
If you want to measure the width of your rim yourself, measure from outer to inner edge of the rim. Here, measure in centimeters and divide the goal by 2.54 to get the goal in inches.
