The purpose of this video is entirely to demonstrate the road noise of Cooper ST Maxx tires after approximately 16000 miles.
Tires are inflated to 40psi. Tire size is 255/80R17 mounted on 17x8" wheels and on a 2015 Ram 1500 RCSB 4X4 w/ 5.7L engine . Tires are balanced conventionally and with Centramatics, high speed ride is very smooth (no vibrations) - just the "mud tire" howl.
