Which rim for which tyres?

Hello, everybody.

for my 4.2 V8 I need new summer tires. Looking for it, I've seen Goodyear bring out the Eagle F1 with emergency run properties. Sounds really interesting only - so far I had 215/60 R15 on the Audi channel cover rims. The Eagle is only available as 225/50 R16 92 W. Can I drive the one on the same rims or do I need new ones? And - is the load capacity of 92 enough on the tires? Fortunately, there is nowhere in the letter a load-bearing index for the summer tyres, only for the winter tyres. There he goes from 93 down to 91, but the usually. yes also up to max. 210 km/h approved.

Greetings
