The rim mounting depth, also known as the offset, is the distance between the mounting surface of the wheel and the centerline of the wheel. This measurement is typically expressed in millimeters and is marked with the letters "ET" (which stands for "Einpresstiefe" in German, meaning "insertion depth").

When the rim mounting depth is specified in the range from ET 30 to ET 45, it means that the wheel is designed to fit cars with a certain range of mounting depths. In this case, the wheel can be mounted on a car with a mounting depth between ET 30 and ET 45.

If the rims have the marking ET50, they cannot be mounted within the range of ET30 to ET45, as they have a larger mounting depth. ET50 means that the mounting surface of the wheel is 50mm from the centerline of the wheel. So, if the car requires a wheel with a mounting depth between ET30 and ET45, a wheel with an ET50 marking would not be compatible.

This means that it is allowable to place the rim 30-45 mm deeper in the car's wheel arch relative to the mounting plane of the rim. The larger the ET, the deeper the rim goes into the wheel arch. The width of the rim is also important here, in order to avoid rubbing the tire against the wheel arch on one side and going beyond the outline of the wheel arch - which is illegal - on the other.

In the context of car rims, the "mounting depth" refers to the distance between the hub mounting surface of the rim and the rim's outer edge. The rim's offset is expressed in millimeters and is usually stamped on the rim along with the letters "ET," which stands for "Einpresstiefe" in German, meaning "insertion depth" in English. A positive offset means that the hub mounting surface is towards the outside of the rim, and a negative offset means that it is towards the inside.

When the rim mounting depth is specified in the range from ET30 to ET45, it means that the rim can be mounted on a car hub with an offset within that range. A rim with a higher ET value has a shallower mounting depth, meaning that the hub mounting surface is closer to the outer edge of the rim, while a lower ET value means that the hub mounting surface is closer to the inside of the rim.

Regarding your second question, if the rims have a marking of ET50, it means that the hub mounting surface of the rim is farther towards the inside compared to a rim with an ET value of 30 to 45. Therefore, the rim with ET50 cannot be mounted within the range of ET30 to ET45. It is important to note that installing a rim with an offset outside the recommended range can cause handling problems, damage to the suspension or steering system, and tire wear issues. It is best to consult with a professional mechanic or a wheel expert to determine the appropriate rim offset for your vehicle.

The designation "ET" refers to the so-called "offset", i.e. the shift of the wheel relative to the assembly axis (wheel). The depth of the rim mounting is numerically indicated in millimeters as the ET value (numbering WM = Einpresstiefe) and defines where in inches of the rim the mounting point away from the wheel axis will be installed. The range from ET30 to ET45 means that rims in this range allow you to set the wheel at different distances from the mounting axis. If the rims are marked ET50, it means that the mounting depth is greater than ET45, and therefore they are outside the range specified by the manufacturer.

This means that body rims can be mounted at a depth of 30 mm to 45 mm from the surface of the ET label (i.e. the distance from the wheel axis to the rim mounting surface), which allows for adjustment to the required driving conditions and tire size.
