Tyre and wheel designations (BMW 5 Series E39)

Example of tire designation:

• 225 - tire width in mm
• 60 - height to width ratio (the height of the tire cross-section is 60% of the width). Unless otherwise specified, the ratio of the transverse dimensions (for example, 195 R 14), then we are talking about the normal ratio of height and width, which for radial tires is 82%.
• R - radial design (radial tire).
• 15 - rim diameter in inches.
• 96 - permissible load characteristic.

Please note: If there is an M + S designation between the numbers 15 and 96, then this is a tire with a winter tread pattern.

• V - letter designation of the permissible maximum speed. The speed designation letter is located at the end of the tire size designation. Speed designation symbols are valid for both summer and winter tires.

Letter designation of speed

Date of tire manufacture

The date of manufacture of the tire is indicated in the manufacturer's code.

Example: DOT CUL2 UMB 3000 TUBELESS

• DOT - Departament of Transportation (uS Department of Transportation)
• CU - manufacturer's abbreviation
• L2 - tire size or tire design
• 3000 - date of manufacture. 30th week of 2000

Note: If instead of a 4-digit number a 3-digit number is specified, followed by a symbol <|, then this means that the tire was manufactured in the last decade. Designation 509 <| for example, it should be read like this: 50th week of 1999.

• TUBELESS - tubeless tire (TUBETYPE - tube tire)

Please note: Since 10/98 new tyres must additionally bear the ECE test number on the sidewall (Economic Commission for Europe). This number indicates that the tires comply with the ECE standard. Tires manufactured from 10/98 without an ECE number do not have permission to operate.

Example of disc wheel designation: 7J x 15 H2

• 7 - rim width in inches
• J - letter designation of the height and outline of the rim flange (B - lower rim height)
• x - letter designation of a solid deep rim
• 15 - rim seat diameter in inches
• H2 - the rim profile has a hump on the outer and inner sides
