OE = Original Equipment

How does the OE process work?

Original Equipment (OE) refers to the parts that your vehicle was fitted with at the factory. It can include various parts of the car, from key components under the bonnet to the tyres the vehicle is fitted with.

The OE process itself can take several years to complete and includes hundreds of tests on the road and in lab conditions. For tyres specifically, automotive engineers and tyre designers work together early in the design process to create a tyre that is specifically engineered for a vehicle.

During this cycle, the tyre manufacturer will look at various aspects of the tyre’s performance and how it affects the intended vehicle. These performance qualities include dry braking, wet braking, dry handling, wet handling, NVH (noise vibration and harshness), rolling resistance and treadwear.

Through the OE process, prototype tyres can clock up hundreds of thousands of miles in diverse weather conditions to ensure they will provide optimal performance.

Goodyear is one of the leading brands in OE with over 600 approvals from more than 30 vehicle manufacturers.

Replacing OE Tyres

When it comes to replacing tyres, it’s always a good idea to consider what tyres your vehicle was originally fitted with. This is especially relevant for new vehicles, where you can simply replace your tyres like for like.

You can do this by finding the specific vehicle mark fitment on your tyres. These marks identify which vehicles the tyres were manufactured for. Audi tyres will be marked with “AO”, Mercedes tyres will be marked with “MO” and BMW tyres will be marked with a star. For a complete list of vehicle mark fitments, see our guide on what OE markings mean.

If you can’t find the vehicle mark fitment, your tyre retailer will be able to help.
