Zorluk: KolayWheels and Tires

A passenger vehicle is fitted with tires marked with the sidewall designation P215/65R15. Match each component of the tire specification code to its correct physical measurement or construction feature.

  • 215Cross-section width of the tire measured in millimeters
  • 65Aspect ratio representing sidewall height as a percentage of cross-section width
  • RInternal carcass ply construction type indicating radial design
  • 15Wheel rim diameter measured in inches

Cevap

215 matches Cross-section width of the tire measured in millimeters; 65 matches Aspect ratio representing sidewall height as a percentage of cross-section width; R matches Internal carcass ply construction type indicating radial design; 15 matches Wheel rim diameter measured in inches.
In standardized automotive tire markings, the format P[Width]/[Aspect Ratio][Construction][Rim Diameter] is used. For P215/65R15, 215 is the tire width in millimeters, 65 is the aspect ratio percentage, R indicates radial construction plies, and 15 is the rim diameter in inches.

Adım Adım Çözüm

1
Decode the initial 3-digit number after the service indicator prefix
215 represents the section width of the tire in millimeters.
Standard metric passenger tire codes list the width across the widest point of the tire in millimeters first.
2
Decode the 2-digit number following the slash
65 represents the aspect ratio percentage.
The aspect ratio expresses the sidewall profile height as a proportion of total cross-sectional width.
3
Identify the internal construction letter
R denotes radial construction.
The letter code directly specifies the orientation of the internal body plies.
4
Decode the final numeric value
15 represents the wheel rim diameter in inches.
The last number in the sizing sequence designates the rim size required for mounting.
