Tire width of 285/50r20

The first figure, 285, in our tire code represents the width of the tire. Now, in a world that’s gone largely metric (America, I’m looking at you), this 285 is in millimeters.

Tire height of 285/50r20

Next up, we have the tire’s height, which is not directly given in the tire size but can be computed from the other measurements. Remember that ’50’ we talked about earlier? That’s a percentage – a 50% aspect ratio. It means the tire’s height is half the width, about 142.5mm, or 5.61 inches. That’s roughly as tall as a grande Starbucks cup. Talk about a ‘grande’ tire!

The sidewall height, also known as the tire profile or aspect ratio, is represented by the number ’50’ in our tire code. It is a percentage of the tire’s width. So, for our specimen, it’s 50% of 285mm, which works out to be 142.5mm. In inch-terms, that’s 5.61 inches. You could stack about nine golf balls to match this height. Makes you appreciate those ‘small’ sidewalls a bit more, doesn’t it?

Rim diameter for 285/50r20

The ’20’ at the end of our tire code is for the rim diameter. Yes, folks, you’ve guessed it, this one is in inches.
