One of the most important features of a tuning vehicle has always been the rims. But that by no means everything can be built in here, that pleases us, we recently published our article "Looking for new rims for the vehicle? That is allowed!“Only shown. And today we would like to dive a little deeper into the matter and deal with the Offset employ. When switching to wider wheels you are allowed to Offset Do not neglect the rims. If the ET does not fit, it endangers driving safety and can even result in the loss of the approval of the vehicle.
What is the offset?
With offset is the distance between the center of the rim longitudinal and the Contact point of the inside of the rim, the so-called flange (Wheel hub), meant. The ET determines how deep there is a wheel in the wheel arch. The dimensions are given as follows:
Example: 8,5 J x 19 H2 ET 40 LK 5 × 112
In our example, ET 40 means that the offset is at 40 millimeters lies. At a Offset = 0 lies the flange exactly in the middle in the wheel. One negative offset is through a Minus sign (e.g. ET -15). In such a case the wheel stands still further outwardsthan inside. At a too high value is accurate the contrary the case. Depending on the manufacturer of the rims, the offset may sometimes be in English is specified. But that is not a problem. Instead of ET it is then with IS or Offset specified. But the value must not be converted.
A wrong offset is fatal!
An wrong offset is prohibited according to STVZO. Each vehicle has individually prescribed values for the offset. It therefore makes sense to use the specified offset be sure must be observed, as driving safety can also be impaired. However, there are a couple of things you can do alternativ at the vehicle make can.
Insufficient offset:
- At one too small offset the wheel faces outwards. Perhaps that allows the tire, on the outside of the wheel arch to grind. The solution: Pull / widen the fenders or maybe it is enough to bead the edges.
- In addition, the track width increases. Solution: On the front and rear axles should the same gauge be driven. Otherwise oversteering or understeering can occur.
Too high offset:
- At one too high offset grinds the wheel from the inside am wheelhouse and in the worst case, the braking system can function impair. Solution: spacers obstruct. They are available in different combinations for almost every type of vehicle.
If you select spacers begins, but you either have to longer screws use for the wheel, or a system that separately on the hub is screwed. The length of the screws must be proportional to the thickness of the spacer enlarged will. in the normally, the right wheel bolts will always be included.
What is the offset of my rims?
Im Partial report or in the general operating permit find the details of Offset. You should have one of the documents ready for acceptance. They are the basis for registration. In case of ABE however, it is sufficient to always have them with you in the vehicle and to comply with an inspection to show. More information on the topic? Is there ... here!
Of course that had not been the case.
