Igor,
What I do is go to the tirerack.com and plug in your model year. They will show you the wheel sizes available that year. (you may have to change years to find when 19" wheels were offered). When you find the 19 x 8 wheel, that will show you the standard tire size for that wheel. With some further clicking, they will show you the different tire widths recommended for that wheel width. I'm thinking that is a front tire size? I've upgraded mine from 205 to 225. I think the widest front size I've seen is 235, but don't quote me.
Enjoy those wheels!
