What The Codes Mean In Deciphering Sidewall Graffiti
Does sidewall graffiti on tires hold any secrets? Author Douglas Adamsmay very well be intrigued at the notion, but the truth is that tire codes tell consumers about the tire’s size, wear, construction and speed rating, among other things. Using the right size tires for your vehicle is an important part of getting the most from your vehicle and increasing mpg. Thanks to Edmunds, here’s your official cheat sheet for breaking down the mystery of the tire codes on your commuter or weekend joy-rider. You’ll have that sidewall graffiti figured out in no time and only have to worry about coming to Car Deal Expert the next time you’re in need of auto loans.

Sidewall graffiti and if your tires could talk
For an example, let’s use 205/55R 16 89V. Let’s see how that breaks down:
- 205 – This is the tire’s section width, which measures the millimeter distance between sidewall edges. The larger the number, the fatter the tire.
- 55 – The aspect ratio comparing section width and height. In this case, the section (or sidewall) height is 55 percent of the section width. The lower the number, the shorter the sidewall meaning improved handling.
- Third R – This is the tire’s construction, in this case radial. Radial has been the standard in the last 20 years, but some trucks still use the same old bias-play construction.
- Fourth 16 – In inches, this is the rim diameter. If you want to upgrade your wheels, you’ll need a set of tires to match the new wheel size.
- 89 – This is the load index, which is translatable via the Maximum Load-Carrying Capacity Per Tire chart. Here, “89″ equates to 1,279 pounds (580 kilograms) per tire. Results can multiplied by four to get total weight capacity.
- Sixth is V – This represents the speed rating, which tells you maximum speed a tire can go over an extended period of time. A car can safely go 149 mph for a period of time with “V”. Your tires might explode if you go over that more than a couple of minutes. For different speed codes, see the link at the bottom of the article.
Other things to consider in your sidewall graffiti
Edmunds suggests that there may be other information, such as a DOT (Department of Transportation) number that helps the DOT track production numbers in the case of a recall. A traction rating of A, B or C may also be found, with “A” being the best. You might see the word “TREADWEAR” with the numbers 180 or 120 along the side. The industry standard is 100, so a tire with a 180 is designed to maintain acceptable tread for traction 80 percent longer than the industry standard. The higher the number, the longer the tread life, although sometimes other scales are used.
