These technical specifications are important details that can determine whether or not that version is compatible with your vehicle and the way you drive.
If several versions are compatible with your vehicle, we recommend that you choose the version with the same specifications as your original equipment tyres, including the correct OE marking.
The OE marking concerns tyres developed in cooperation with car manufacturers that meet more specific requirements, proper to each car brand. For example, the "MO" marking means that the tyre is approved by Mercedes for its vehicles.
However, the OE marking is not a requirement as long as the size, speed, and load indexes are respected.
You can also safely select a version with higher speed rating or load index; however, higher speed or load capability can negatively impact tread life and ride comfort.
