I put this tire on a Cadillac CTS-V 2012 coupe [yes a 345 30 19 will fit on the coupe], used an 11 inch rim with 50 mm offset]. I had been using M/T drag radials, 305 40 19, they did not get the grip that these tires do. The Nitto's balanced with almost no added weight also. Great tire IMO. The Caddy runs 118 mph @11.8 ET, grip is important!
