Speed Rating Chart
The tire speed rating chart is a special code chart that matches letters to speeds:
- Each letter (A through Z) means a different maximum speed
- The chart shows you exactly how fast (in miles per hour or kilometers per hour) you can go with each letter
Here's an example: Look at your tire and find the marking similar to "245/55 R 19 103 H". The letter "H" at the end is your Speed Rating. When you look up "H" on the chart, it means your tire is safe to drive up to 130 miles per hour. (But remember, always follow the speed limits on the road!)
