Rim width and tire width are two closely related sizes. Flexible tire sidewalls alow a single tire size to be mounted on a rim of various widths. There is a rim width range for every tire size, but on the other side, there is a tire width range for every single rim size.
When replacing a rim or tire with a wider one you could put a question in two different ways:
What rim widths fit to my tire? (e.g.195/65 R15)
The answer is: "Rim widths corresponding to tire 195/65 R15 are: 5.5", 6.0", 6.5" and 7.0" ". The information related to all other tire dimensions can be found in Wheel/Rim Size Calculator.
If you want to mount a wider or narrower tire on an existing rim you could ask a question in another way:
What tire widths fit to my wheel/rim?
When replacing OEM tire with a wider aftermarket tire, width of the rim should be taken into account because each rim width corresponds to only a few tire widths.
For example, appropriate tire widths for 6.0" 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. Equivalency table presented below may help you to make a rational decision about tire dimension you need for a given wheel/rim dimension.
Tire widths for a wheel/rim size chart - Equivalency table
Tire widths for a wheel/rim size chart shows what tire widths fit displayed wheel/rim sizes - shows tire width range for a given rim width: minimum, ideal and maximum tire widths (e.g. for an 7" wheel/rim, following tire widths can be fitted: 195, 205, 215 or 225).
