How to Measure the Rim Width of Dunlop Tires

Having the correct width for a vehicle equipped with Dunlop tires helps with tire sidewall flex room. This give a tire great performance. The wrong width may wear tires out faster then they should. Tire safety is also of the utmost importance as well. The correct way to measure tire rim width is taught with a few specific tips.

READABLE TIRES

1. Find the letters and numbers that are on the sidewall of the tires. Take a white crayon over the stamped numbers and letters. This will allow you to view the numbers better.


2. Write down the set of numbers and letters from the tire. An example will be “P245/70R17.”


3. Start with the series of numbers and letters before the forward slash mark. This example would be “P245.” The P stands for passenger vehicle. An LT would stand for light truck. The number 245 represents the tire rim width.

UNREADABLE TIRES

1. Put the vehicle in the park position. Put the emergency brake on firmly. Then put a jack underneath the car. Do this by using the vehicle manual instructions because all vehicles will be different. Use a wrench to remove hubcap and loosen lug nuts. Use to jack to lift vehicle off the ground and then remove the lug nuts.  Remove the tire from the car.


2. Stand tire up and measure across the top of the tire with a tape measure. Do this in millimeters. Tire widths are always represented in millimeters and not inches. For example if a tire is 213 mm, the tire rim is almost at the standard width of 215.


3. Use the Internet to find the Victory Library Tire Size & Width Chart website. Find the website by doing a search with your preferred search engine. Use the chart to find the size closest to the measurement from your tire. An example is a 211 tire would then be the next size higher. Therefore, the correct rim size would actually be 215.
