Wheels parameters:

For an example of size: 7,5x17 ET40 PCD 5*114,3 Dia 70.1 , consider the notation for these parameters. - width - 7,5 or 7,5J means the width of the disk shelves in inches
- diameter - 17 or R17 is the installation of the wheel size in inches
- Between the bolt distance (PCD) and number of holes - 5*114,3 means 5 holes with a distance of 114,3.
- Et (ET) -40 or ET40 is the distance from the geometric center of the disk shelf to the fitting point to the hub in millimeters. The smaller the flyout, the more the drive is out
- Dia -70.1 the size of the hub in millimeters. Sometimes indicated without a fractional part
- Bolt -12*1,5 diameter and thread pitch of the bolt / nut in millimeters

Tyres sizes:

Using the wheel size example 215/45 R17 , consider what these options mean. - Width -215 - tire width in millimeters
- Height -45 - this value is specified in percent. The height of the wheel profile in millimeters is calculated as a percentage of the width, for our case this will be215 *45 & # 37; = mm
- Diameter -17 or R17 - tire setting diameter
