Wheel sizes of GMC

Minimum tire size for the entire range of GMC models is: 205/75R15.

Limit parameters for all models:

  • Tire size: from 205/75R15 to 265/75R15;
  • Disk size: from 15x6.5 to 17x8.0.

Structurally, the vehicle wheel combines a wheel disk and a tire.

Tire marking:

Standard European vehicle tire marking is a symbol code that may look, for example, like this - 175/65R15, where:

  • 175 is width of the work face of the tire;
  • 65 is percentage of profile height of tire width;
  • R15 is type of construction (R - radial) and inner diameter (in inches).

Disc specifications:

Wheel disc is characterized by the following key parameters:

  • Width of rim B (distance between shelves);
  • Disc diameter D (distance is measured by the level of shelves);
  • Wheel offset ET (distance from the axis of symmetry of the disk to the plane of abutment to the hub).
  • Diameter of circumference of the location of mounting holes PCD .

Important: vehicle wheel offset is determined by the formula: ET = A - B/2, where A is distance between the inner plane of the disk and the part in contact with the hub, B is disk width.
