The upcoming 2022 Cadillac Blackwing ultra-high-performance luxury sedans will be fitted as standard with tires specially designed for them. More specifically, the 2022 Cadillac CT4-V Blackwing and 2022 Cadillac CT5-V Blackwing will both ride on Michelin Pilot Sport 4S tires.
The high-performance summer tire features a multi-compound tread composition. In fact, each tire features three rubber compounds. The predominant one is known as “R compound”, and is a high-performance material covering the majority of the tread.
Mirza Grebovic, Cadillac Performance Variant Manager, provided further details during a recent interview with GM Authority executive editor Alex Luft.
“They are TPC [Tire Performance Criteria] spec, which means they are uniquely built for our V-Series Blackwing cars,” Grebovic explained. “So when you go buy them on Tire Rack or anywhere else, it will say TPC, which means they were made for our cars.
What the TPC spec impacts is “the stiffness of the tire and the characteristics of the rubber.” Grevobic explains that “the team went through various submissions of tires to make sure that the steering, the wet performance, and the dry performance was all to our liking, and we picked a specific spec just for us.”
The Cadillac Blackwing models are of different sizes and weights, and have different power outputs. They are also rear-wheel-drive only, since Cadillac decided not to offer them with all-wheel-drive. The resulting variety of performance requirements means that each axle of each vehicle has its own unique tire size.
The Cadillac CT5-V Blackwing will be the most powerful model Cadillac has ever put into production, since its supercharged 6.2L V8 LT4 engine produces 668 horsepower and 659 pound-feet of torque. Its tire requirements are clearly different from those of the CT4-V Blackwing, so it will wear 275/35ZR19 rubber at the front and 305/30ZR19 at the rear.
As of this writing, both Cadillac Blackwing models will go into production at the GM Lansing Grand River plant in Michigan on July 5th. Starting prices are $59,950 for the CT4-V Blackwing and $84,990 for the CT5-V Blackwing.
