What 225/45R18 means

225/45R18 means a 225 mm section width, a sidewall 45% as tall as it is wide (about 101 mm), on a 18-inch wheel. The overall diameter works out to about 26.0 inches, which is what a replacement size has to match closely.

225/45R18 is the typical original-equipment size on the BMW 3 Series and Mercedes-Benz C-Class. Trims and option packages differ, so check the sticker inside your driver's door or the sidewall of the tire on the car before ordering.

The two letters after the size on a tire (for example 102T) are its load index and speed rating. A replacement should meet or exceed the ones on your door sticker; our load and speed check reads them for you, and how to read a tire size explains the rest of the sidewall.
