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.

225 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 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"

75%

Aspect Ratio

The ratio of the height of the tire's cross-section to it's width. 75 means that the height is equal to 75% 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 75 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".

R

Construction Method

Radial. The R in the P225/75R15 102S 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 (P225/75R15 102S), 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 (P225/75R15 102S, 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.

102

Load Index/Service Description

2060lb load. The tire assigned numerical value used to compare relative load carrying capabilities.

The 102 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.

S

Speed Rating

180mph. 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 (P225/75R15 102S) 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.

265 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 265 indicates that this tire is 265 millimeters across from the widest point when mounted and measured on a specified width wheel.

70%

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.

By converting the 265mm to inches (265 / 25.4 = 10.43") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 5.21".

Toyota Motor Corporation is a Japanese multinational automotive manufacturer headquartered in Toyota, Aichi, Japan. In March 2014, Toyota's corporate structure consisted of 338,875 employees worldwide[4] and, as of October 2016, was the ninth-largest company in the world by revenue. As of 2016, Toyota is the world's largest automotive manufacturer. Toyota was the world's first automobile manufacturer to produce more than 10 million vehicles per year which it has done since 2012, when it also reported the production of its 200-millionth vehicle.[6] As of July 2014, Toyota was the largest listed company in Japan by market capitalization (worth more than twice as much as #2-ranked SoftBank) and by revenue.[8][9]

Toyota is the world's market leader in sales of hybrid electric vehicles, and one of the largest companies to encourage the mass-market adoption of hybrid vehicles across the globe. Cumulative global sales of Toyota and Lexus hybrid passenger car models achieved the 10 million milestone in January 2017. Its Prius family is the world's top selling hybrid nameplate with over 6 million units sold worldwide as of January 2017.

The company was founded by Kiichiro Toyoda in 1937, as a spinoff from his father's company Toyota Industries to create automobiles. Three years earlier, in 1934, while still a department of Toyota Industries, it created its first product, the Type A engine, and its first passenger car in 1936, the Toyota AA. Toyota Motor Corporation produces vehicles under five brands, including the Toyota brand, Hino, Lexus, Ranz, and Daihatsu. It also holds a 16.66% stake in Subaru Corporation, a 5.9% stake in Isuzu, as well as joint-ventures with two in China (GAC Toyota and Sichuan FAW Toyota Motor), one in India (Toyota Kirloskar), one in the Czech Republic (TPCA), along with several "nonautomotive" companies.[11] TMC is part of the Toyota Group, one of the largest conglomerates in the world.
