I've seen the Kia Stinger sitting on Continental tires as well as Michellin tires and haven't found a direct specification as to which tires will be on there, but I did manage to find the tire sizes that will be available.
The V6 Stinger will receive:
[F] 225/40/R19
[R] 255/35/R19
(vented Brembo brakes will be standard. Four piston front calipers and two piston rear calipers)
The 4-cylinder Stinger will receive:
225/45/R18 square setup
