Many have done it , but apparently, it isn't recommended by the tire manufacturers. They want at least 17X7.5 size rims, but the SEs are 17X7. Do so at your own risk, or get 225/45-17s.

Whats the diameter and width?

I've seen and heard of 235's on 7" wide rims and 7'5.... 235 would be ideal for 8" wide though.

Look at the title of the post, hes talking about the 2K SE 17" rims.
