Hi Carol. Acura has gone to
Hi Carol. Acura has gone to great lengths to engineer the TLX in all trim levels to reach or exceed optimal performance. The car looks great in person. Example: Acura reformulated the tires to reduce road friction, and... removed 11 lbs of dead-weight from the disc brake assembly.( reduces wheel bounce and vibration sound transfer.) By changing the rim size, you generally off-set the increase in rim diameter by decreasing the height of the tire side-wall. This looks great, but generally stiffens the cars ride and increases road vibration transference to the interior of the car. Proceed with caution. Take the car out for an hour test drive, I think you'll like it, please let us know how it goes. Thanks...
