Cadillac will be offering a 19-inch all-season tire and wheel package on the 2011 CTS sedan and sport wagon. The 19’ Goodyear Eagle RS-A2 tires use carbon fiber in the tire’s sidewall to keep more rubber on the road, thus delivering better handling. An asymmetric tread design enhances traction and cornering that makes for a quieter ride. The package is available on the 3.6 liter V6 performance and premium models and will cost $850.
