Your own placard is the authority. You will find it on the on the driver's door jamb, on the B-pillar. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tire.
What changes on this car

The 50 profile leaves about 138 mm of sidewall on the 20in rim, and the V rating covers 240 km/h.
Michelin's UK data also lists an 18in 265/60 R18 114 for the G 580. No second source confirms it as a factory fitment, so it is not given here; check the door placard before fitting a smaller wheel.
