The first three numbers give you the width of the tire in mm. So if you are looking at a 295/45/17 tire, this means the tire is 295 mm wide. The second set of two numbers is the “aspect ratio” that tells you how tall the sidewall is in millimeters. In the case of the 295/45 tires referenced above that means you take 295 multiple by .45 (45%) to get the sidewall height of 132.75mm. Hope this helps you out.
