HOW TO CHOOSE CORRECT WHITE WALL TRIM PORT-A-WALL SIZE?

Tire sidewall height must be taken into account while choosing the Portawall size

Calculate sidewall height of your tires using the ratios seen in below image

You can find the correct size by subtracting 46,75mm (1 27/32") from sidewall height

Example; sidewall of a 205/55/16 tire is 112,75 mm or 4 7/16 inch (205mmx0,55)

112,75 mm (4 7/16") - 46,75mm (1 27/32") = 66 mm (2 19/32).

A sidewall which will not exceed 66 mm (2 19/32) can be used for this tire.
