If you have P245/50ZR16
Goodyear Eagle GS-C tires
or P275/4OZR17 Goodyear Eagle F1-GS tires, they
must roll in a certain direction for the best overall
performance. The direction is shown by an arrow on
the sidewall. Because these tires are directional, they
should be rotated as shown here. These tires should
only be moved from front to rear and rear to front on
the same side of the vehicle.
Don't include the compact spare tire in your
tire rotation.
