One of the best promo ads involving the S550 Mustang that we have seen to date, this Nitto Tires video featuring the 2015 Mustang fitted with Nitto 555 Gen 2 tires also gives us a look at the 2015 Mustang RTR sans livery.
Although seen drifting and power sliding around a track in the video, the Nitto NT555 G2 features aggressive directional tread pattern akin to its predecessor while providing enhanced performance in dry/wet handling, braking, and acceleration.
Check out the video in the forums.
