Located on the inside of the wheel, wheel markings are a series of numbers and letters that provide coded information about the wheel such as its diameter, width or offset. However, you need to know how to read them - and once you do, you will see there is much important information left for you.
What You Need To Know Before Purchasing
The sequence of numbers and letters help to identify not only the appropriate car wheels, but also other attributes and features. Have you ever wondered what the mysterious letter “J” means (the one placed after the number indicating the rim width, in inches)?
Wheel markings explained
To better illustrate the meaning of the markings, let's take a look at the following example: "7.5Jx16H2 ET35.” In this case:
7.5 is the wheel size, meaning it is 7.5 inches wide (1 inch = 25.4mm)
16 is the wheel diameter, also expressed in inches
ET35 is the offset - the distance of the hub mounting surface to the wheel’s symmetry axle expressed in millimetres.
The letters J and H2 in the letter and number combination
The letter “J” means a tyre bead profile. This is the marking used to define the wheel collar profile you should never ignore. Wheel collars and tyres must be compatible. There are various types of wheel edges listed as follows:
The edges of these different types may sometimes differ from one another. It's important to remember that some types of cars and wheels can come under more than one profile.
