Yes, 205/50-15 and 195/60-14 (winter)

And i'm always embarrassed by Europeans' fluency in English contrasted 
with my relative
incompetence in most European languages.  I can annoy the French with 
my terrible pronunciation,
btu that's about it.

Sounds like you want to get a different wheel.

If you send me your email, I'll scour my hard drive for some technical 
info on what tires fit on what width rims, etc.
