At any load up to the maximum and speeds up to 160km/h my door placard and the owners manual show 32F/32R with 275/35-19 front and 285/30-20 rear tyres.
For speeds over 160km/h the owners manual shows 33F/38R for full load without M Driver's Package and only 39F/44R with M Driver's Package, likely to ensure tyre integrity over tyre life at 285km/h with a full load of 4 passengers and luggage.
