#### 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.

#### 155 millimeters 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 155 indicates that this tire is 155 millimeters across from the widest point when mounted and measured on a specified width wheel. Because many people think of measurements in inches, the 155mm can be converted to inches by dividing the width in millimeters by 25.4 (the number of millimeters per inch).

155mm / 25.4 = 6.10"

#### 80%

###### Aspect Ratio

The ratio of the height of the tire's cross-section to it's width. 80 means that the height is equal to 80% 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 80 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 155mm and that its section height is 50% of 155mm. By converting the 155mm to inches (155 / 25.4 = 6.10") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 3.05".

#### R

###### Construction Method

Radial. The R in the P155/80R13 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 (P155/80R13), 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.

#### 13" wheel

###### Rim Size

The 13 indicates the tire and wheel diameter designed to be matched together.

Tires that have a rim diameter expressed in inches (P155/80R13, 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.

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

The 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.

###### Speed Rating

mph. 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 (P155/80R13) 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.

###### 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.

Because many people think of measurements in inches, the 175mm can be converted to inches by dividing the width in millimeters by 25.4 (the number of millimeters per inch).

175mm / 25.4 = 6.89"

#### 70%

###### Aspect Ratio

The ratio of the height of the tire's cross-section to it's width. 70 means that the height is equal to 70% 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 70 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 175mm and that its section height is 50% of 175mm. By converting the 175mm to inches (175 / 25.4 = 6.89") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 3.44".

#### R

Nissan Motor Company Ltd, usually shortened to Nissan, is a Japanese multinational automobile manufacturer headquartered in Nishi-ku, Yokohama. The company sells its cars under the Nissan, Infiniti, and Datsun brands with in-house performance tuning products labelled Nismo.

The company traces its name to the Nissan zaibatsu, now called Nissan Group.

Since 1999, Nissan has been part of the Renault–Nissan–Mitsubishi Alliance, a partnership between Nissan, Mitsubishi Motors and French automaker Renault. As of 2013, Renault holds a 43.4% voting stake in Nissan, while Nissan holds a 15% non-voting stake in Renault. From 2009 to 2017 Carlos Ghosn served as CEO of both companies. In February 2017 Ghosn announced he would step down as CEO of Nissan on 1 April 2017, while remaining chairman of the company[7]

In 2013, Nissan was the sixth largest automaker in the world, after Toyota, General Motors, Volkswagen Group, Hyundai Motor Group, and Ford.[8] Taken together, the Renault–Nissan Alliance would be the world’s fourth largest automaker, however Nissan is the leading Japanese brand in China, Russia and Mexico.[9]

Nissan is the world's largest electric vehicle (EV) manufacturer, with global sales of more than 275,000 all-electric vehicles as of mid-December 2016.[10] The top-selling vehicle of the carmaker's lineup is the Nissan Leaf, an all-electric car and the world's top-selling highway-capable plug-in electric car in history; more than 240,000 have been sold worldwide as of September 2016.[
