Chevrolet offers revised 16- and 17-inch aluminum wheels, and 17-inch all-season tires are now optional on LT models. Other new features include a tire-pressure monitor and Hydroboost brakes that provide more reserve stopping power and decreased pedal effort, according to Chevrolet. A traction assist feature is available on two-wheel-drive Tahoes equipped with a locking rear differential. The trailering package includes a 7-to-4 pin brake wiring adapter. Finally, for added safety, there is now a front-passenger seatbelt reminder.
