Did You Know - Tire Info

What you'll see on the tire

1. The width of the tire (in mm)
2. The sidewall height (displayed as a percentage of the width)
3. The type of tire and the wheel size

Common Misconceptions 

“A certain sidewall size is always the same”: 

• Wrong. Remember that the sidewall is a percentage of the width, so a 205/45 will have less sidewall than a 295/45.

“All tire widths are created equal”: 

• Wrong. Different manufacturers have their own biases towards actual measurements. You may find certain brands run consistently narrower or wider than others. Sidewalls should be consistent, however.
