Tires change from 205/55R16 to larger

[Din]

Hi peeps, I drive a corolla 2011 with original tires 205/55R16.
I would like to keep 16 inch, not modify any but go on a larger tire. No low profile tire.
What size would you suggest ?
I know there will be a speedometer variance though.
Thanks in advance for your assistance.

Don't use a larger diameter but this will be the correct diameter with a wider contact patch. If you insist on going to a larger diameter just go up one size to a 215/55R16.
