Tire size specifies a tire's type, width, aspect ratio, construction, rim diameter, load index, and speed rating.
A letter that corresponds with the maximum service speed for a tire. A speed rating isn't, however, a recommendation to exceed speed limits, and doesn't indicate how well a tire handles or corners.

A 3-part U.S. DOT labeling requirement. Treadwear is relative; a rating of 200 has treadwear of 2 times longer than a rating of 100. Traction is a measurement of straight-ahead wet braking; AA is the highest, followed by A, B, and C. Temperature resistance specifies the maximum temperature the tire can withstand; A is the highest, followed by B and C.

MAX LOAD (lbs)
The most weight a tire is designed to carry.

The highest cold inflation pressure a tire can maintain in pounds per square inch.

The range of widths a tire size can fit on.

The width the tire must be mounted on to ensure it meets its dimensional requirements.

The measurement between the widest point of the outside sidewall to the widest point of the inner sidewall.

TREAD DEPTH (in 32nds)
The distance between the outer edge to the grooves in a tire.

The measurement around the center of the outer tread.

The number of times a tire rotates fully over the course of 1 mile.

How To Read A Sidewall

There is a lot of useful information molded into the sidewall of every tire. Included are manufacturer and tire name; section width; aspect ratio; construction; rim diameter; speed rating; load range; treadwear, temperature and traction labeling and other required designations.

All tires sold in the United States must meet the size standards for bead shape, width, diameter and other parameters established by a recognized standardizing organization. World leaders among such organizations are the European Tire and Rim Technical Organization (ETRTO) and the U. S. Tire and Rim Association (T&RA). Both use a partially metric-based system. Virtually all passenger tires on the market today use the rim and tire sizing, load and inflation system established by these bodies. All U. S. highway tires must also meet U. S. D.O.T. standards as indicated by the letters 'D.O.T.' on the sidewall.

The several tire size designations in use today depend on when a vehicle was manufactured and whether it was domestically produced or imported. All tire-sizing systems used today provide information about a tire's dimensions. Among the most important for proper fitment is height, width and load carrying capacity. P-Metric: This is the United States version of a metric sizing system established in 1976. P-Metric passenger car tire sizes begin with "P," which simply means "Passenger."

Metric: This European tire sizing system is similar to P-Metric but does not use the "P" designator.
Alphanumeric: This system was established in 1968 and is based on the tire's load carrying capacity, correlated to its overall size. The tire's capacity and size are indicated by letter designations from "A" (smallest tire, lowest capacity) to "N" (largest tire, highest capacity). An example of an Alphanumeric tire size is BR78-13. "B" shows size/load, "R" indicates radial construction, "78" is the aspect ratio, and "13" is the wheel size in inches.
Numeric: This is the oldest standardized tire sizing system for passenger car tires. When this system was adopted, tire aspect ratios were either 92 or 82. For example, a 7.00-14 tire has a section width of 7 inches, a rim diameter of 14 inches and an aspect ratio of 92. The low profile equivalent size tire with an aspect ratio of 82 would be 7.35-14.
Example: P215/65R15 89H

This indicates a passenger car tire. If the first character in the size designation is a "P," the tire is a "P-Metric" tire and is engineered to standards set by the T&RA. If there is no "P", the tire is engineered to ETRTO standards and is a metric tire. The standards set by T&RA and ETRTO have evolved together and are virtually interchangeable.

These numerals indicate the tire section width in millimeters. This is the dimension from sidewall to sidewall. A tire's section width will vary depending on the rim to which it is fitted. The section width will be larger on a wide rim and smaller on a narrow rim. Therefore, each tire is measured to specific rim width. (To convert millimeters into inches, divide by 25.4.)

This two-digit number indicates the tire's aspect ratio. It compares the tire's inflated section height, which is the distance from the bead to the tread, to its section width (maximum). An aspect ratio of 65 means that the tire's section height is 65% of the tire's section width. For clarity, the section width in millimeters is separated from the aspect ratio by a slash (/).

This letter indicates the type of ply construction in the tire's casing or carcass. "R" means radial. "D" means diagonal, referring to bias ply tires. "B" means belted for belted-bias ply tires. Never mix radial tires with any other construction on a car.

The "15" indicates the rim diameter in inches. It is the diameter of the tire bead seat ledge in the rim. Most tires are built to inch standards for rim diameters. However, some tires are built to millimetric rim dimensions. Always match the tire's rim diameter to the wheel rim diameter. This is important for safety. NOTE: A millimetric rim has a different shape than an inch rim; they are not interchangeable.

The service description is an alphanumeric combination, consisting of two parts, a number and a letter. In this example, "89" is the load index, which represents the load carrying capacity. (All passenger car tires in the U.S. are also marked with their actual load limit in pounds.) The letter part is the speed symbol, 'H,' in this example. This is the maximum speed for which the tire is rated at the load specified by the load index. In this example, 'H' means speeds up to 130 mph. Dunlop does not recommend the use of any of its products in excess of legal speed limits. Speed Ratings do not necessarily imply that the performance (handling and grip) of the tire meet the performance standards implied by the ratings. Tire speed ratings must exceed the maximum speed capability of the vehicle to which they are fitted. Not all tires sold in the U.S. are speed rated, although many modern performance and luxury cars are equipped with speed rated Original Equipment tires. It is important to remember this when replacing the tires on your vehicle. Replace tires with equivalent or higher speed rated tires. Do not downgrade speed ratings from Original Equipment ratings.
NOTE: Speed Ratings - where applied are indicative of high performance characteristics based on European ECE 30 Indoor Wheel testing as performed by Dunlop and are not valid for damaged, altered, repaired, under-inflated, overloaded, excessively worn, or re-treaded tires. Dunlop does not recommend the use of any of its products in excess of legal speed limits.

Some tires carry additional markings related to service. An M&S or M+S designation means the tire is rated suitable by the manufacturer for mud and snow use. The guidelines are set by the Rubber Manufacturers Association (RMA) in the United States.

This is a marking which means that the tire meets M&S/M+S requirements without the drawbacks of noise and rolling resistance associated with the traditional deep-lug winter tires. The M&S/M+S designation means that the tire is suitable for normal all-weather driving applications. Tires that meet the requirements of the M& S designation have better winter traction compared to those without the M&S symbol.
North American tire manufacturers and the RMA have established a voluntary, industry-wide definition for passenger and light truck tires intended for use in SEVERE SNOW CONDITIONS. Tires must meet a performance-based criteria featuring tread pattern, construction elements and materials which generally provide snow performance superior to that of tires bearing the RMA current M&S Rating. Such tires will display a mountain/snowflake symbol.

The 10 digit D.O.T. code number molded into the sidewall designates the manufacturer and plant where the tire was produced, the tire line and size, and the week and year the tire was manufactured.

All passenger tires are marked on the sidewalls to indicate maximum load capacity and maximum inflation pressure. Truck tires will indicate recommended pressure for maximum loads for both dual and single application.

Red dots on Dunlop high performance tires for match mounting purposes. These dots mark the 'high spot' of the tire, which is then matched with the 'low spot' on the rim to cancel out harmonic vibration.
