P

Intended Use Of Tire

Passenger Vehicle. When a tire size begins with a P, it signifies the tire is a p-metric size that was designed to be fitted on vehicles that are primarily used as passenger vehicles. This includes cars, minivans, sport utility vehicles and light duty pickup trucks (typically 1/4- and 1/2-ton load capacity). The use of p-metric sizes began in the late 1970s and they are the most frequently used type of tire size today.

205
mm wide

Tire Width

Following the letter(s) that identify the type of vehicle and/or type of service for which the tire was designed, the three-digit numeric portion identifies the tire's section width/cross section in millimeters.

The 205 indicates that this tire is 205 millimeters across from the widest point when mounted and measured on a specified width wheel. Because many people think of measurements in inches, the 205mm can be converted to inches by dividing the width in millimeters by 25.4 (the number of millimeters per inch).

205mm / 25.4 = 8.07"

65%

Aspect Ratio

The ratio of the height of the tire's cross-section to it's width. 65 means that the height is equal to 65% of the tire's width.

Typically, following the three digits identifying the tire's width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.

The 65 indicates that this tire size's sidewall height (from rim to tread) is 50% of its width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall. The lower the number, the lower the sidewall. We know that this tire size's section width is 205mm and that its section height is 50% of 205mm. By converting the 205mm to inches (205 / 25.4 = 8.07") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.04".

R

Construction Method

Radial. The R in the 205/65R15 94H size identifies that the tire has a radial construction in which the tire's plies "radiate" out from the center of the wheel. Radial tires are by far the most popular type of tire today representing over 98% of all tires sold.

If the R in the size was replaced with a D (205/65R15 94H), it would identify that the internal tire body plies crisscross on a diagonal and that the tire has a "bias ply" construction. Tires using this construction are for light truck and spare tire applications.

15" wheel

Rim Size

The 15 indicates the tire and wheel diameter designed to be matched together.

Tires that have a rim diameter expressed in inches (205/65R15 94H, as well as 8, 10, 12, 13, 14,15, 17, 18, 19, 20, 22, 23, 24, 26 and 28) are called "inch rim" sizes. These are the most common types of tire sizes and are used on most cars, minivans, vans, sport utility vehicles and light duty light trucks.

Tires and wheels with unique rim diameters should never be combined with traditional "inch rim" tires and wheels.

Load Range/Ply Rating

This tire has a ply rating of which indicates how much load the tire is designed to carry at it's specified pressure.

94

Load Index/Service Description

1898lb load. The tire assigned numerical value used to compare relative load carrying capabilities.

The 94 represents the tire's service description. A service description identifies the tire's load index and speed rating. Service descriptions are required on all speed rated (except for Z-speed rated) tires manufactured since the early 1990s.

H

Speed Rating

210mph. The maximum speed that the tire can sustain for 10 minutes.

Today, the only tires that continue to include the speed rating "in" the tire size (205/65R15 94H) are Z-speed rated tires. In this case, following the two digits used to identify the aspect ratio are the letters ZR to identify the tire's speed rating (Z) and its internal construction (R). Since 1991, all other speed ratings are identified in the tire's Service Description.

P

Intended Use Of Tire

Passenger Vehicle. When a tire size begins with a P, it signifies the tire is a p-metric size that was designed to be fitted on vehicles that are primarily used as passenger vehicles. This includes cars, minivans, sport utility vehicles and light duty pickup trucks (typically 1/4- and 1/2-ton load capacity). The use of p-metric sizes began in the late 1970s and they are the most frequently used type of tire size today.

The 225 indicates that this tire is 225 millimeters across from the widest point when mounted and measured on a specified width wheel. Because many people think of measurements in inches, the 225mm can be converted to inches by dividing the width in millimeters by 25.4 (the number of millimeters per inch).

225mm / 25.4 = 8.86"

55%

Aspect Ratio

The ratio of the height of the tire's cross-section to it's width. 55 means that the height is equal to 55% of the tire's width.

Typically, following the three digits identifying the tire's width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.

The 55 indicates that this tire size's sidewall height (from rim to tread) is 50% of its width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall. The lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43".

dodge

Dodge is an American brand of cars, minivans, sport cars, sedans, super cars, muscle cars, and sport utility vehicles manufactured by FCA US LLC (formerly known as Chrysler Group LLC), based in Auburn Hills, Michigan. Dodge vehicles currently include the lower-priced badge variants of Chrysler-badged vehicles as well as performance cars, though for much of its existence Dodge was Chrysler's mid-priced brand above Plymouth.

Founded as the Dodge Brothers Company machine shop by brothers Horace Elgin Dodge and John Francis Dodge in the early 1900s,[3] Dodge was originally a supplier of parts and assemblies for Detroit-based automakers and began building complete automobiles under the "Dodge Brothers" brand in 1914, predating the founding of Chrysler Corporation. The factory was located in Hamtramck, Michigan and was called the Dodge Main factory from 1910 until its closing in January 1980. The Dodge brothers both died in 1920, and the company was sold by their families to Dillon, Read & Co. in 1925 before being sold to Chrysler in 1928. Dodge vehicles mainly consisted of trucks and full-sized passenger cars through the 1970s, though it made memorable compact cars (such as the 1963-76 Dart) and midsize cars (such as the "B-Body" Coronet and Charger from 1962-79).

The 1973 oil crisis and its subsequent impact on the American automobile industry led Chrysler to develop the K platform of compact to midsize cars for the 1981 model year. The K platform and its derivatives are credited with reviving Chrysler's business in the 1980s; one such derivative became the Dodge Caravan.

The Dodge brand has withstood the multiple ownership changes at Chrysler from 1998 to 2009, including its short-lived merger with Daimler-Benz AG from 1998 to 2007, its subsequent sale to Cerberus Capital Management, its 2009 bailout by the United States government, and its subsequent Chapter 11 bankruptcy and acquisition by Fiat.

In 2011, Dodge, Ram, and Dodge's Viper were separated. Dodge said that the Dodge Viper would be an SRT product and Ram will be a manufacturer. In 2014, SRT was merged back into Dodge. Later that year, Chrysler Group was renamed FCA US LLC, corresponding with the merger of Fiat S.p.A. and Chrysler Group into the single corporate structure of Fiat Chrysler Automobiles.
