OE = Original Equipment

What do the OE tyre markings mean?

To show that replacement tyres are engineered to original equipment standards, an OE marking is embossed into the sidewall of a tyre. These markings indicate which car manufacturer a tyre has been designed for.

For example, tyres manufactured specifically for Audi will have AO embossed on the tyre’s sidewall. For Mercedes, MO will be shown on the tyre’s sidewall. And for BMW, you will see the star symbol. For each vehicle manufacturer there is a unique sidewall marking to match.

OE tyres are developed by tyre manufacturers in conjunction with the vehicle manufacturer. Goodyear is one of the leading brands in OE with over 600 approvals from more than 30 vehicle manufacturers.
