How to Read Your Tire’s Sidewall

The sidewall of your tire is covered in numbers and letters that can look like a secret code, but they actually contain a lot of useful information. Learning to read a few of them helps Franklin drivers make smarter decisions about their tires and understand what they are actually buying.

The most prominent marking is the tire size, something like a series of numbers and letters that describe the tire’s width, the height of the sidewall relative to that width, and the wheel diameter it fits. When you replace tires, matching this size to what your vehicle calls for is important for safety and performance. You will also find a load index and speed rating that indicate how much weight the tire can carry and how fast it is rated to travel.

One of the most overlooked markings is the date code, which tells you when the tire was manufactured. Tires age even when they are barely used, and the rubber can harden and crack over the years, so an old tire with plenty of tread can still be unsafe. There is also treadwear and traction information that can help you compare tires. Knowing how to find this information helps you avoid buying old stock or the wrong size.
