Installed the premium all season 265/60/17 tires. Rides smooth as glass and very quiet.. The Falken 265/70/17 ATW3 were somewhat noisy and the ride was not smooth.
The height drop is noticeable makes the entry and exit much easier. 2-3 mph actual speed difference ( 60 mph on the speedometer is actually 57-58 ) and the GX has better acceleration due to the tire diameter in effect lowering the rear differential gear ratio.
