When it comes to parts of a car, there are few more important to vehicle stability, maneuverability, and safety than a car’s tires. Tires are responsible for carrying the weight of the vehicle, and require routine maintenance and replacement to guarantee that they’re performing at their best. Tire markings, however, remain a mystery to most consumers. Read on to learn what many of these tire markings mean.
Information on a Tire
Your tires’ sidewalls contain a lot of information. On a typical tire, you will find the following information.
- size designation.
- service description (load and speed ratings).
- temperature grade.
- maximum inflation pressure.
- traction and tread wear grade.
- maximum load rating.
- U.S. Department of Transportation tire ID number.
- nominal width of the tire.
- aspect ratio.
- ply composition and materials used.
- and, the rim diameter code.
Generally, most consumers needn’t concern themselves with most of this information. For those checking on their tires at home, the most important things are inflation levels and the size of tires.
All tires are manufactured with inflation information on their sidewalls. While the exact location might be slightly different depending upon the brand of tire, typically, inflation information can be located by looking for words similar to “Maximum load 300 at 44 PSI.” PSI stands for pounds per square inch, and refers to the inflation amount for your tire.
Checking your tire pressure regularly is important, and can be done using an air pressure gauge. Make sure that the air pressure in your tires is within the PSI limits for your tire but also be sure you inflate to the proper PSI per vehicle manufacturer instructions.
Over- or underinflated tires can lead to a blow out or other accident. The National Highway Traffic Safety Administration recommended carrying a tire pressure gauge within your vehicle and checking your vehicle’s tires once per month.

Tire Size Information
The other most important thing a car owner needs to know is the size of his or her tires. Usually, tires are sized using the metric system. Size markings can be confusing, and usually read, for example, “205/60R16.” However, once you know how to decode these markings, they’re very straightforward.
The first three digits always refer to a tire’s width. In the case above, the tire’s width is 205 millimeters. The second part of the number refers to a tire’s aspect ratio, or the height of the bottom of the sidewall to the top of the tire where the tread is. This number is presented in a percentage, so the aspect ratio is 60 percent of 205 millimeters, or 123 millimeters.
Finally, the third number, “R16,” refers to the rim diameter. Strangely, this number is usually displayed in inches, although sometimes it will be shown in millimeters. Knowing your tires’ size information is important when it comes time to replace your tires, or if you’re replacing your tires’ rims.
